Editing Simple Styles: ComboBox Background

Tue, 24 Nov 2009 23:42:06 Z

Hi, I am using the SimpleStyle ComboBox from WPF SimpleStyles VS 2008 project I downloaded from MSDN, and I would just like to change the background of the control using the Background property on the control. What I've tried to do isn't quite working. I think the answer lies in properly setting a Binding on the Background Property of PART_EditableTextBox.

Thank you up front for any assistance.

How to setup a Binding Style

Fri, 20 Nov 2009 17:16:08 Z

I have like 15 Textboxes in a Control, each textbox inherits a style that sets several properties. Howerver, each textbox currently has its text binding but I have a lot or redudance in the bindings. I want to be able to build a style for the binding and have the textbox add the path and mode to the exisiting binding. for instance each textbox has

<Binding NotifyOnValidationError="True"
                             NotifyOnTargetUpdated="True"
                             NotifyOnSourceUpdated="True"
                             ValidatesOnExceptions="True"
                             UpdateSourceTrigger="LostFocus" />

in addition to the Path and Mode.

But I dont want to type this over and over again for every textbox i add. is there a way to place half of the binding properties in a style and the other half set them in the textbox?

Thanks

How do I call a function (with parameters) from xaml?

Wed, 25 Nov 2009 01:22:02 Z

Hi, I want to insert a calculated value (QuotePrice) to a record's field in a datagrid.
The calculation uses one field from the current record (ItemType, which is used to determine CostPrice and MarkUp) and two fields from the parent record (NumberOfItems and SubsidyType). I.e. I want to pass three parameters to the formula.

How do I call a formula with three parameters from xaml?
Is there an alternative way to do this?

I want to call function getQuotePrice in the window's code:

Partial Public Class fdlgQuote

    ' Lots of omitted code
    '...

    Public Function getQuotePrice(Byval CostPrice As Double, NumberOfItems As Integer, SubsidyType As Integer) As Double
        '...
        ' 20+ lines of code and function calls to determine QuotePrice
        '...

        Return QuotePrice
    End Function

End Class

This is the abbreviated layout of my window:

<WpfToolkit:DataGrid x:Name="dgQuoteItem"
                                 ItemsSource="{Binding Source={StaticResource DetailQuoteItemView}}">
        <WpfToolkit:DataGrid.Columns>
            <WpfToolkit:DataGridComboBoxColumn Header="Product"
                                               x:Name="cboFkProduct"
                                               SelectedValueBinding="{Binding fkProduct}" SelectedValuePath="uidProduct" DisplayMemberPath="Product"
                                               ItemsSource="{Binding Source={StaticResource cvsProduct}}" />
            <WpfToolkit:DataGridTextColumn Header="Quote Price" Binding="{Binding QuotePrice}" /> 
        </WpfToolkit:DataGrid.Columns>
    </WpfToolkit:DataGrid>
</Grid>
</Window>

Binding to XML in WPF

Fri, 13 Nov 2009 03:24:42 Z

I have an XML column in a table in a SQL Server database. I want to read this column, then two-way databind its fields into WPF controls or a WPF DataGrid. What is the best .NET object to use for this and what would be the proper syntax? I'm using VS 2010 Beta 2.

Can't get a DataGrid to update

Wed, 25 Nov 2009 04:33:08 Z

I have a WPF Toolkit DataGrid bound to an ObservableCollection<Car> in my view model. Car has a PropertyChanged event and the setters of each of its two string properties fire the event. I also have the grid's SelectedItem property of the grid bound to a property in the view model of type Car, also called SelectedItem.

On the same window as the grid, I have buttons for add, modify and delete. Add and modify open a dialog window with two textboxes, one for each Car property. Delete just shows a confirm dialog then does the delete.

For add and delete, I add or delete an item from the ObservableCollection and the grid updates itself as expected. However, for modify it does not. At first, my Car did not use PropertyChanged and after some searching I found that it needed to for the grid to update when an individual item's properties changed. But now that I am using PropertyChanged, the grid still doesn't update.

I've tried changing the values of the SelectedItem in my view model as well as directly changing the item on the collection.

What am I doing wrong?

searching and listing WPF resource dictionaries in a folder

Fri, 20 Nov 2009 01:25:57 Z

I'm making a WPF application that is going to have multiple skins branded in by our build system. Ideally we would like the application to list off the skins available as builds will have one to many skins.

At runtime is there a way to enumerate all the Resource Dictionaries in a specific folder? Or at the very least produce a list of the XAML which I can parse for specific names?

I want to avoid hard coding the XAML filenames in my C# as this is a changing situation.

Selective Binding for Collections

Mon, 23 Nov 2009 13:14:19 Z

Hello, I have a 4-level TreeView that is bound to custom classes that have generic base collections.

In order to display the data, I am using the following hierarchical data template:

<HierarchicalDataTemplate ItemsSource="{Binding Level2}">



                                    <TextBlock Tag="lvl1" Text="{Binding Name}" />



                                    <HierarchicalDataTemplate.ItemTemplate>

                                        <HierarchicalDataTemplate ItemsSource="{Binding Level3}">



                                            <TextBlock Tag="lvl2" Text="{Binding Name}"></TextBlock>



                                            <HierarchicalDataTemplate.ItemTemplate>

                                                <HierarchicalDataTemplate ItemsSource="{Binding Level4}">

                                                    

                                                    <TextBlock Tag="lvl3" Text="{Binding Name}"></TextBlock>

                                                    

                                                    <HierarchicalDataTemplate.ItemTemplate>

                                                        <HierarchicalDataTemplate>

                                                            <TextBlock Tag="lvl4" Text="{Binding Name}"></TextBlock>

                                                        </HierarchicalDataTemplate>

                                                    </HierarchicalDataTemplate.ItemTemplate>

                                                    

                                                </HierarchicalDataTemplate>

                                            </HierarchicalDataTemplate.ItemTemplate>



                                        </HierarchicalDataTemplate>

                                    </HierarchicalDataTemplate.ItemTemplate>



                                </HierarchicalDataTemplate>

I am setting the tree view's ItemsSource (Level1) in the code-behind class.

Now this works fine and the data is being displayed correctly. However, I don't want to display level 3 items unless they have children (the level 4 collection has items). Is it possible to do that using xaml (i.e. modifying the above piece of code)?

TreeView - can you override how the keyboard navigation works?

Mon, 09 Nov 2009 22:10:40 Z

In a TreeView control, the items are navigated via the keyboard with the arrow keys. I'm wondering if it's possible to override this behavior so that the nodes are navigable via the TAB key instead?

I want to do this because I actually have a control I'm creating that's derived from TreeView and TreeviewItem ... but of course the default keyboard navigation still exists, i just want to change it.

selection change in wpf

Wed, 05 Sep 2007 10:20:21 Z

I’m trying to convert some code written in .net 2.0 to WPF

Is there something equaling in WPF to the .net 2.0 combo box selectionChangeCommitted event ?

Meaning that I want the event to be fired only after a user change the item in the combo and not when it’s done by code

Thanks

"Global" pick-lists with change-notification (EntityFramework)

Mon, 23 Nov 2009 15:45:31 Z

Hi folks,

in my WPF-app (tabbed MDI / MVVM), there can be numerous open windows. In these windows/tabs, there may be ComboBoxes that serve as pick-lists. For instance, for a Contact-entity, there could be a combo that shows the available person-titles; each Contact would have to be associated with one of those titles.

Ultimately, I would like any open window/tab containing such a title-lookup to automatically update its list of titles (i.e. the combobox) whenever there is a change, such as a new title or one that has been updated.
Also, since these pick-lists only change on rare occasions, their content is being made available by means of a static class that itself holds a reference to the "cache"-class which holds an ObservableCollection(Of Title) .
The problem is that WPF (or the EntityFramework?) doesn't seem to like this approach - as long as my cached data is an ObservableCollection, I can't seem to successfully bind a ComboBox'es SelectedItem to the underlying entity (i.e., the ComboBox'es SelectedItem-prop will equal Nothing).
If I instead use a List(Of Title) , the binding will work just fine, but then I won't have any change-notification.

Any ideas of how to doing this right ..?

Cheers,
Olaf

Notifying subscribers of a cached set of data

Wed, 18 Nov 2009 13:03:05 Z

Hi folks,

I have a collection of records that is being used throughout an application for i.e. pick-lists. For the sake of an example, let's assume that there is many different windows in which the user administers contacts and can pick an (academic) title from a combobox, with the combo bound to the collection I mentioned before.
Since there's only rare occasions at which the collection of titles changes, that collection is being loaded when it's first needed and kept in a "cache" (i.e. a shared/static class/collection). At runtime, there can be a number of open windows in which a title-combo is part of the window. Now, the user opens a window in which (s)he i.e. adds a new title to the collection (or changes an existing one).

What approach would I have to take in order to automatically have all open windows with a title-combo be notified of the change? I seem to be running in circles around this ...

Cheers,
Olaf

Multiple object selection by rubber band with Rotate Resize and Move in WPF

Wed, 25 Nov 2009 04:44:31 Z

Hi
I am trying to develop a graphical application which allows users to drop objects on a canvas. I have created button for each shape which when clicked, add a shape on the canvas. The shape is surronded by a contentcontrol. This contentcontrol is attached to a style with the microsoft rotate, resize and move classes. Thus, the shape can be rotated, resized and moved. Now I am planning to create a select-deselect tool. The user may select (using rubberband) more than one object and perform rotate, resize and move on them together. Then, on clicking outside the selection, the objects rests on the canvas again retaining the changes.
I don't have any designer canvas or designer item (shapes for adding) concept in my app. So, on rubberband selection, I get the objects as per the rubberband's coordinates, width and height. After getting the objects, I detach them from the main canvas and add them to another canvas bounded by the same contentcontrol. The selection is perfect but I cannot perform resize as the objects insode the new canvas and contentcontrol are - Contentcontrol containing a shape. As this contentcontrol have fixed size, it doesnot allow me.
So I tried another way, on selection I remove the styled contentcontrol from the objects and took the shpes only and added it to a new canvas bounded by a styled contentcontrol. Now The shapes looses the size and they also loose their position on screen.
It would be great if someone helps me telling me the way how to achieve this functionality (keeping in mind that I don't have designer canvas ot item architecture).
NB: The code is quite big so I was unable to post it. But I think the exaplanation was quite vivid.

Setting focus on the ListView

Wed, 25 Nov 2009 04:15:31 Z

Hi all,

i want to select the listview while form load event. In my application i have created the list view through xaml as follows

<ListView  Name="lvDetail" Grid.Row="1" Grid.Column="0" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Grid.ColumnSpan="6" ItemsSource="{Binding}" SelectionChanged="lvDetail_SelectionChanged" Focusable="True">
        </ListView>

data population is done through code behind as follows

        GridView grdView = new GridView();
            lvDetail.View = grdView;
            GridViewColumn grdViewCol;
            foreach (string str in disList)
            {
                char[] seperator = { ',' };
                string[] strProperty = str.Split(seperator);
                grdViewCol = new GridViewColumn();
                grdViewCol.Header = strProperty[(int)PropertyType.HeaderCol];
                grdViewCol.DisplayMemberBinding = new System.Windows.Data.Binding(strProperty[(int)PropertyType.BinderCol]);
                grdView.Columns.Add(grdViewCol);
            }

the content of the list view is the list of my businesslayer object. Everthing is working well except to focus my grid programatically while form load. i used different code from different web sites..

Looking forward to hear from you..

Thanks in advance

Making a Grid the content of a RowDetailsTemplate DataTemplate in a WPF DataGrid

Mon, 23 Nov 2009 22:44:13 Z

I have built a Grid of content dynamically in code and I want this Grid to be used as the DataTemplate in the RowDetailsTemplate of a WPF DataGrid. The DataGrid looks like this:

<DataGrid Name="dataGridHouseholdMembers" Grid.Row="0" Grid.Column="0"
                            ItemsSource="{Binding HouseholdMembers}" AutoGenerateColumns="False"
                            Style="{StaticResource dataGridStyle}"
                            RowDetailsVisibilityMode="VisibleWhenSelected">
                            <DataGrid.Columns>

                                            <sys:String>X</sys:String>
                                        </col:ArrayList>

                                </DataGridComboBoxColumn>
                            </DataGrid.Columns>
                            <DataGrid.RowDetailsTemplate>
                                <DataTemplate>
                                    <GroupBox Name="groupBoxPersonDemographics"></GroupBox>
                                </DataTemplate>
                            </DataGrid.RowDetailsTemplate>
                        </DataGrid>

I want to do something like:

groupBoxPersonDemographics.Content = _gridPersonDemographics;

but when I try to do so I get the message that groupBoxpersonDemographics is not in context.

What is the proper syntax to load the grid as the content of the DataTemplate? Can I do it prior to loading any data into the DataGrid (I only want the row details to be visible for the SelectedItem) or must I do it when the RowDetailsVisibilityChanged event fires for the DataGrid?

How can I get the session from the session ID

Tue, 24 Nov 2009 16:21:21 Z

My WPF application is in partial trust so I can't use SaveFileDialog for downloads. Instead, I create links that call an asmx webservice. I need to somehow pass the session over since clicking on a hyperlink doesn't pass the session. I need the currentuser from the session to determine what version of the download I should give them. I thought that I could encrpyt the session ID and then pass it as a query string parameter. I got the session ID over but I can't figure out how to actually get the session from the session ID.

Does anyone have any ideas? Or maybe a better way to do this?

Here's the code on the asmx side.

[WebMethod(EnableSession = true
)]
        [ScriptMethod(UseHttpGet = true
)]
        public
 void
 Download(string
 label, string
 key, string
 redirect)
        {
            try

            {
                string
 sharedCookie = Security.DecryptValue(redirect);
                string
[] sharedArgs = Strings.Chop(sharedCookie, ";"
);
                string
 sessionID = Strings.Chop(sharedArgs[0], "="
)[1];                
                //Rest of code...

            }
            catch
 (Exception ex)
            {
                HandleDownloadException(ex, Context.Response);
                return
;
            }
        }

concurrency violation the deletecommand affected 0 of the expected 1 records.for C# using WPF dataset to sql

Tue, 24 Nov 2009 00:10:23 Z

Hello,

sorry for the long Title, but as said i am getting error message: concurrency violation the deletecommand affected 0 of the expected 1 records., this happens when i go and add a new/ or insert new to sql database using Dataset/dataadaptor, I am using WPF as for the Gui interface and using C# for the backend programming, here is the code right now i got that error's out on sqlda.Update(sqlds, "Workers"); and i seen there are ways of fixing this but i only seen it fixed for VB and sadly i dont know VB to well. so if anyone can let me know how to fix in C# that would be awesome, here is the code below of the delete event:

 private void btn_delete_Click(object sender, RoutedEventArgs e)
        {

                    MessageBox.Show("Record Deleted Successfully");
                    
                    //sqlds.AcceptChanges();
                    
                    sqlda.Update(sqlds, "Workers");
                }
            }
            else
                MessageBox.Show("Please select then click on delete button");
        }

Thank you

Black Line at top of all WPF applications in Windows 7 Aero

Wed, 25 Nov 2009 01:04:34 Z

I've been noticing that my WPF application acts strangely. But the more I've been looking the more I see the same peculiarity and realize it's more than just my application, but WPF apps in general.

I'm running Win7 with VB2010 and .NET 4.0 installed. I have noticed that when using the Aero Peek function of the Win7 interface, a black line appears between the title bar and the client area. When the window is displayed for real the black line disappears and the entire window contents shift upward about 3-4 pixels.

It is happening for all WPF applications I am currently running, including VS2010's IDE, my own applications, and even programs like XamlPadX.

I'm running Win7 Pro, Dell Precision 390, 4GB, Core 2 Duo, NVIDIA Quaddro FX3500.

Is anyone else seeing this behavior? I only have this computer so I can't check another Win7 machine.

Cannot catch client exception at all

Wed, 25 Nov 2009 00:50:57 Z

Hi all,
I am using wsHttpbinding for an internet application using WCF service and WPF. I am running into a bug when I make more than 40 consecutive calls. If make make about 30 calls then it doesn't crash and after that I can make more than 60 calls. Then after a certain point it would crash again. I am trying to catch this error and I cannot seem to catch it at all. The error I am getting is An unhandle exception of type 'System.Reflection.TargetInvocationException' occurred in Unknown module. Additional information: Exception has been thrown by the target of invocation.

I have tried all these catches and none of them are catching the exception. Even in the WCF Service I have added the try/catch exceptions to but cannot catch it either. It looks like the call never made it to the WCF service. Am I doing something wrong?

Here are my catch blocks

            catch (FaultException er)
            {
                MessageBox.Show(er.Message);
            }
            catch (CommunicationException er)
            {
                MessageBox.Show(er.Message);
            }
            catch (TimeoutException er)
            {
                MessageBox.Show(er.Message);
            }
            catch (System.Reflection.TargetInvocationException er)
            {
                MessageBox.Show(string.Format("Inner: {0}\n\n Message: {1}", er.InnerException.Message, er.Message));
            }
            catch (Exception er)
            {
                MessageBox.Show(er.Message);
            }

Popup with AllowsTransparency="True" is allowing click events to pass through?

Tue, 24 Nov 2009 18:44:44 Z

I have a Popup with the AllowsTransparency property set to true, and I'm defining a custom border (rounded edges) for it. I have a ListBox on the popup ... the problem is that when I click on an item in the listbox, the mouse click goes through the popup and ends up putting focus or clicking on a control that happens to be underneath the popup.

Is there a way around this? I tried adding another Grid layer below the ListBox that had IsHitTestVisible="False", but that didn't work.

Style and Menu. Who invented this?!

Mon, 23 Nov 2009 00:04:15 Z

Hello,

I have the following MenuItem style:

      Style style = new Style { TargetType = typeof(MenuItem) };     
      Trigger over = new Trigger { Property = MenuItem.IsMouseOverProperty, Value = true };      
      over.Setters.Add(new Setter(Control.BackgroundProperty, new SolidColorBrush((Color)ColorConverter.ConvertFromString("#FFCC00"))));      
      over.Setters.Add(new Setter(Control.ForegroundProperty, new SolidColorBrush((Color)ColorConverter.ConvertFromString("#202020"))));
      over.Setters.Add(new Setter(Control.BorderBrushProperty, Brushes.Red));
      style.Triggers.Add(over);

And I am applying to all menu items as follows:

      Menu menu = new Menu { ItemContainerStyle = style };

The problems I have is:

1. When the mouse is over a Menu Item I don't get a red border. I get a gray one. This is really strange.
However, if click it, it becomes red. This makes no sense. What am I doing wrong?

2. The styles are not applied to the Menu Items that have a submenu. Have no idea why.

3. I am not able to style the buttons on the submenus.

Could someone, please, help me out with this?

I am starting with WPF and styling is driving me crazy.

Thanks,
Miguel

Binding ItemsControl in MVVM

Tue, 24 Nov 2009 21:17:29 Z

Hi,

One thing I'd love to solve before the long weekend...

I have a MVVM app.

The ViewModel is defined partially as:

public partial class MyViewModel
{
        // Initialized elsewhere, etc.
        private Story mMyStory;

        public static readonly DependencyProperty StoryProperty = DependencyProperty.Register(
            "Story", typeof(Story), typeof(MyViewModel));

        public Story MyStory
        {
            get { return mMyStory; }
            set { SetProperty("Story", ref mMyStory, value); } 
        }
}

public partial class Story : ObservableItem  // implements INPC
{
        // Assume mChapters is initialized and implements INPC
        private ObservableCollection<Chapter> mChapters;

        public static readonly DependencyProperty ChaptersProperty = DependencyProperty.Register(
            "Chapters", typeof(ObservableCollection<Chapters>), typeof(Story));

        public ObservableCollection<Chapter> Chapters
        {
            get { return mChapters; }
            set
            {
                SetProperty("Chapters", ref mChapters, value);
            }
        }
}

My View code-behind sets up the ViewModel and sets the DataContext of the View to the ViewModel.

m_viewModel = new MyViewModel(this.FullName);

this.DataContext = m_viewModel;

What I am having trouble with is getting the "Chapters" to show up properly in a ItemsControl in the View. I want the ItemTemplate to contain a user control, with the user control's DataContext set to be a Chapter (this control works when creating one directly).

This is what I have so far:

<ItemsControl x:Name="chaptersPresentation" 
              HorizontalAlignment="Stretch"
              Padding="5"
              ItemsSource="{Binding Story.Chapters}">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Horizontal" 
                               HorizontalAlignment="Stretch"/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <Border Background="Yellow" Margin="2">
                <StackPanel>
                     <local:MyCustomControl x:Name="imageControl"
                                                         Style="{StaticResource ChapterStyle}" />
                </StackPanel>
            </Border>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

But I get an InvalidCastException: Unable to cast object of type '...MyViewModel' to type 'System.Windows.DependencyObject'

Thanks,
WtS

Master Page in WPF

Thu, 19 Nov 2009 22:53:01 Z

Hello,

I have created a WPF window with a Dock Panel and a menu on docked to top.

Is it possible to use this as a "master page" and dock other xaml files to the middle section of the Dock Panel?

Is this possible in WPF?

Removing AdornerLayer from ScrollContentPresenter

Tue, 24 Nov 2009 23:19:13 Z

Is there a way to remove the automatically generated AdornerLayer in the ScrollContentPresenter? I need my Adorner to go outside the extents of the ScrollViewer. The workaround posted here ( http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/350dfb88-a145-48d5-8227-0db2e6fd9229 ) will not work. My Adorner needs to track the position of the objects its adorning so if I reach around to the topmost Window adorner, when content is scrolled in an inner ScrollViewer the Adorner doesn't move. I've tried hooking up to LayoutChanged on the UIElement I want to track but since that gets triggered anytime layout changes for the entire application it's much too slow.

How to animate a child control in response to a parent event or trigger

Mon, 23 Nov 2009 16:01:54 Z

Hi all,

I have a custom button which inherits from Button. I have styled my custom button with a custom arrow by setting the button's template according to an ArrowDirection dependency property. Here is the relevant xaml for setting a button with a left arrow:

    <Style TargetType="{x:Type local:SoftKeyButton}">
        <Style.Triggers>
            <MultiTrigger>
                <MultiTrigger.Conditions>
                    <Condition Property="ArrowDirection" Value="Left"/>
                    <Condition Property="IsEnabled" Value="True"/>
                </MultiTrigger.Conditions>
                <Setter Property="Template" Value="{StaticResource LeftArrowControlTemplate}" />
            </MultiTrigger>
        </Style.Triggers>
    </Style>

with a corresponding ControlTemplate:

    <ControlTemplate x:Key="LeftArrowControlTemplate" TargetType="{x:Type local:SoftKeyButton}">
        <DockPanel LastChildFill="True">
            <local:Arrow
                DockPanel.Dock="Left"
                HorizontalAlignment="Left"
                VerticalAlignment="Center"
                Content="M 0,10 l 10,-10 l 0,20 Z"/>
            <ContentPresenter Margin="2" HorizontalAlignment="Left" VerticalAlignment="Center" RecognizesAccessKey="True"/>
        </DockPanel>
    </ControlTemplate>

In the arrow's style, I am trying to update just the arrow in response to the parent Button's click event. I guess I don't understand attached properties like I should, but I was hoping that I would be able to do something like this below where I listen for the parent's IsPressed property to change.

    <Style TargetType="{x:Type local:Arrow}">
        <Setter Property="Focusable" Value="false"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type local:Arrow}">
                    <Border 
                        Name="Border"
                        Margin="0" 
                        CornerRadius="2" 
                        Background="{StaticResource NormalBrush}"
                        BorderBrush="{StaticResource NormalBorderBrush}"
                        BorderThickness="1">
                        <Path
                          HorizontalAlignment="Center"
                          VerticalAlignment="Center"
                          Fill="{StaticResource GlyphBrush}"
                          Data="{Binding Path=Content,RelativeSource={RelativeSource TemplatedParent}}" />
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="local:SoftKeyButton.IsPressed" Value="true">
                            <Setter TargetName="Border" Property="Background" Value="{StaticResource PressedBrush}" />
                            <Setter TargetName="Border" Property="BorderBrush" Value="{StaticResource PressedBorderBrush}" />
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

I realize that this isn't the correct syntax, but what do I need to change so that I can update this style when the parent button is pressed? I have also tried setting up an EventTrigger here as well, but it doesn't work either. Any tips would be appreciated. Thanks and have a great day!

Cannot move Image from one Canvas to another Canvas

Tue, 24 Nov 2009 15:50:05 Z

WPF 3.0
I want to take an Image off of one canvas and add it to another
Routine is:

private void setSessionDraggedImage(Image i)
{
            sessionCarousel.xamDataCarousel1.DataItems.Remove(i);
            if (i.Parent == null)
            {
                Image newi = new Image();
                svCanvas.Children.Add(newi);
                svCanvas.Children.Remove(newi);
                svCanvas.Children.Add(i);    // error thrown
                i.MouseMove += new MouseEventHandler(pageDragging);
                i.MouseLeftButtonUp += new MouseButtonEventHandler(pageDraggingStops);
                i.CaptureMouse();
            }
}

Error occurs at the line "svCanvas.Children.Add(i);"
Note that i.Parent == null before the line is hit
Note that I can add & remove a new Image to the target Canvas.
At the point of the error, it appears that i.Parent has been set to the new canvas "under the covers", but an error is still thrown
WHY?

Get TreeView "node" from ContextMenu

Wed, 18 Nov 2009 23:11:44 Z

I have a TreeView that is populated using XmlDataProvider and has an applied HierarchicalDataTemplate. There are no TreeViewItems creating the nodes. How do I determine which node is gettng the click to display the context menu?

I can use a TreeViewItem if that makes it easier and someone shows me how to use it with a HierarchicalDataTemplate.

WPF on Displays which are not part of the Desktop

Tue, 10 Nov 2009 18:43:19 Z

Hello,

I am currently developing a windows xp solution where an external display is used to display hardware related information. This display is therefore not mounted next to the pc with the primary display - in our case it is mounted in another room (next to the observed hardware).

Because just hardware related information is displayed we don't need mouse and keyboard interaction.

We just want to use WPF because it is very powerful and allows us to use XAML and Co as usual for developing and

designing the graphical output.

Now to my problem:

To use WPF on this display as far as I know I have to add it into the desktop. But by using this approach we have to face the situation that the user is able to interact with the display. He is able to use the mouse pointer and can move windows o this area of the desktop. All of this is not desired. In best case the user should not be aware that this display exists at all.

Is there anybody out there with an idea how to use WPF and display it on a display which is not part of the desktop?

- Maybe create a special WPF "Window" which renders directly to the graphics card output?

- Replace the graphics card memory part by another target area?

- Take something from Remote Desktop Connections?

- Take something from VirtualDesktops, Second Desktops?

- ...

Any idea?

Best regards,

stefan

PasswordBox for login

Tue, 24 Nov 2009 17:15:07 Z

I have a login menu wherein I am trying to capture the password(and store it for length and other verification)
public void login(object sender, RoutedEventArgs e)
{
    DisplayBox = new PasswordBox();
    Mygrid.Children.Add(DisplayBox);

}

void OnClick(object sender, RoutedEventArgs e)
{
    //Check password strength
   if (Display.Length < 4)
        MessageBox.Display("Password error");
}

How do I get the full password in my OnClick() routine to do the check?

Custom control and data binding in generic.xaml

Wed, 21 Oct 2009 08:00:10 Z

I'm starting out with custom controls in WPF and I don't understand how to create data binding in the generic.xaml. This is an example generic.xaml I have:

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:EngineBase"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008">
    <Style TargetType="{x:Type local:CustomControl1}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type local:CustomControl1}">
                    <Grid x:Name="grid" Background="Transparent" RenderTransformOrigin="0.5,0.5">
                        <TextBlock Margin="8" Text="{Binding MyText}" Name="textblock1" TextWrapping="Wrap" Foreground="White"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>

As you can see I want to bind the 'Text' property of 'textblock1' to a property called 'MyText'. So, in the cs-file I have this:

using System.Windows;
using System.Windows.Controls;

namespace EngineBase
{
    public class CustomControl1 : Button
    {
        public static readonly DependencyProperty MyTextProperty =
            DependencyProperty.Register("MyText", typeof(string), typeof(CustomControl1),
            new PropertyMetadata(new PropertyChangedCallback(CustomControl1.OnMyTextPropertyChanged)));

        public string MyText
        {
            get { return (string)GetValue(MyTextProperty); }
            set { SetValue(MyTextProperty, value); }
        }

        static CustomControl1()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomControl1), new FrameworkPropertyMetadata(typeof(CustomControl1)));
        }

        private static void OnMyTextPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            CustomControl1 myControl = d as CustomControl1;

            //Now what???

        }
    }
}

But this doesn't seem to be enough to cause 'textblock1' to bind to the 'MyText' property. Do I need to inherit the 'INotifiyPropertyChanged' interface to the 'MyText' wrapper or is there another way when I'm creating custom dependency properties?

Thanks for help!

Passing Hight-Lighted Text in other applications or Windows to WPF Application

Thu, 19 Nov 2009 03:29:09 Z

We have a contact management system that has the ability to place a call to their telephone. We are looking for ways to integrate with other applications and Windows in general w/o using TAPI due to its complexity.

As an alternative, we were thinking of have a hotkey designated that would take any hightlighted text and pass to our application. Say for instance you were in Notepad where you have a list of phone numbers. I would like to call one of them by highlighting the phone number and hitting F10 (or whatever key) and our application will interpret this by taking the hightlighted value and pasing to our internal methods to then place the call.

Let me know if anyone has any direction in accomplishing this sort of feature.

Thanks,

Steve

SPECIAL CHARACTERS IN XAML via VB.net

Tue, 24 Nov 2009 19:37:25 Z

Hello

I need to create Xaml code via vb.net.

In particular I need to create a line like thsi one:

Stringbuilder.Append("Currency=""{Binding Path= " & PathName & ",Mode=TwoWay}"" />")

where the Pathname is a string .

My problem is that because this pathname is typed by the user there is a chance that someone will use characters like // \\ etc.

I would like to allow the user to use those characters but if i do so during the generation of xaml code with


        xaml = Stringbuilder.ToString
        Dim sr As New MemoryStream(Encoding.ASCII.GetBytes(xaml))
        Dim pc As New ParserContext()

i get en exception

so how can I make those character acceptable in a parsercontext?

GroupBox looks different between .Net4 and .Net4 Client Profile

Tue, 24 Nov 2009 19:23:55 Z

We've just noticed that the WPF GroupBox visual look is different depending on whether the project is built for .Net4 or .Net4 Client Profile. The one for .Net4 have a groupbox header that occupies the whole top bar, while .Net4 ClientProfile GroupBox looks just like the old style one. Is there any reason behind this? Also, will there be other wpf control visual diferences between the two?

Help with event in Custom Control

Tue, 24 Nov 2009 19:19:25 Z

Hi! I devellop a CustomControl with a layout like a TileList. Everything is fine except that when I double click an item in the list, the SelectedItem and SelectIndex are null and -1. Does anyone knows why?

Here's my Generic.xaml:

<ResourceDictionary

VS2010 on Windows 7: Taskbar Snapshot Not Updating

Tue, 24 Nov 2009 19:16:27 Z

[rant]I am reposting this message because an MSFT moderator moved the original message to a dead forum, effectively deleting the question. If someone has a suggestion for a better forum, please let me know and I will post the question there. However the "Where is the forum for..." forum is NOT the proper location.[/rant]

I've been looking through the Win7 support provided by .NET 4.0, but I haven't discovered how to resolve this one. My application is logging information to the main window. However when I hover over the Taskbar Icon for the running program, changes aren't updated. I thought Win7 was supposed to handle live updates on the Taskbar icon previews as well as Aero Peek, etc.

Am I missing something or do I have to manually tell the Taskbar whenever my main window has updated itself?

XPS Print PageRange

Fri, 09 Jan 2009 01:24:40 Z

Hello,

I need to enable the ability to print a range of pages of an XPSDocument. I am using code similar to the example taken from MSDN as below:

PrintDialog pDialog = new PrintDialog();  

pDialog.PageRangeSelection = PageRangeSelection.AllPages;  

pDialog.UserPageRangeEnabled = true;  

// Display the dialog. This returns true if the user presses the Print button.  

Nullable<Boolean> print = pDialog.ShowDialog();  

if (print == true)  

{  

XpsDocument xpsDocument = new XpsDocument("C:\\FixedDocumentSequence.xps", FileAccess.ReadWrite);  

FixedDocumentSequence fixedDocSeq = xpsDocument.GetFixedDocumentSequence();  

pDialog.PrintDocument(fixedDocSeq.DocumentPaginator, "Test print job");  

}

A user can select a range on the PrintDialog, but when the document prints, it prints all the pages - not just the range.

Using Vista 32 bit with Studio 2008, WPF 3.0 Application.

Any Ideas?

Thanks,

David
