Load a usercontrol dynamic

Question

Hi

I have in my application a accordion control with hyperlinkbuttons. When a user press for example the hyperlink
"Products", then i want to load the user control "Products.xaml". How i can do that ???

Answer 1

Hi,

Do you want to instantiate a UserControl based on a string.
Like you have Products So i will instantiate "Products.xaml"
For this you can use Activator.CreateInstance("Products")

Answer 2

depending on how you are trying to do things if you just have a content presenter besides your accordion control with a name then you can just in the click event for a give button set it to a new instance of the control you would like

OnProductClick(object sender,RoutedEventArgs e)
{
  _myContent = new Products();
}

Answer 3

Where do you want to put this UserControl? You need to creat this UserControl then add it to the VisualTree.

Say you have a Grid called "container" as a placeholder for this control in your page:

Products p = new Products();

this.container.Children.Add(p);

thanks, that works but i found something else.

What do you think about the Navigation Framework and the uri mapper. Which solution is better ??

i mean this:

<UserControl 
    x:Class="SilverlightApplication4.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" 
    xmlns:uriMapper="clr-namespace:System.Windows.Navigation;assembly=System.Windows.Controls.Navigation"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
    mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480">

  <Grid x:Name="LayoutRoot" Style="{StaticResource LayoutRootGridStyle}">

    <Border x:Name="ContentBorder" Style="{StaticResource ContentBorderStyle}">

      <navigation:Frame x:Name="ContentFrame" Style="{StaticResource ContentFrameStyle}" 
                              Source="/Home" Navigated="ContentFrame_Navigated" NavigationFailed="ContentFrame_NavigationFailed">
        <navigation:Frame.UriMapper>
          <uriMapper:UriMapper>
            <uriMapper:UriMapping Uri="" MappedUri="/Views/Home.xaml"/>
            <uriMapper:UriMapping Uri="/{pageName}" MappedUri="/Views/{pageName}.xaml"/>
          </uriMapper:UriMapper>
        </navigation:Frame.UriMapper>
      </navigation:Frame>
    </Border>

    <Grid x:Name="NavigationGrid" Style="{StaticResource NavigationGridStyle}">

      <Border x:Name="BrandingBorder" Style="{StaticResource BrandingBorderStyle}">
        <StackPanel x:Name="BrandingStackPanel" Style="{StaticResource BrandingStackPanelStyle}">

          <ContentControl Style="{StaticResource LogoIcon}"/>
          <TextBlock x:Name="ApplicationNameTextBlock" Style="{StaticResource ApplicationNameStyle}" 
                               Text="Anwendungsname"/>

        </StackPanel>
      </Border>

      <Border x:Name="LinksBorder" Style="{StaticResource LinksBorderStyle}">
        <StackPanel x:Name="LinksStackPanel" Style="{StaticResource LinksStackPanelStyle}">

          <HyperlinkButton x:Name="Link1" Style="{StaticResource LinkStyle}" 
                                     NavigateUri="/Home" TargetName="ContentFrame" Content="Startseite"/>

          <Rectangle x:Name="Divider1" Style="{StaticResource DividerStyle}"/>

          <HyperlinkButton x:Name="Link2" Style="{StaticResource LinkStyle}" 
                                     NavigateUri="/About" TargetName="ContentFrame" Content="Info"/>

        </StackPanel>
      </Border>

    </Grid>

  </Grid>

</UserControl>

Hi,

Navigation Framework is much more easier to manage.

But it depends on what kind of application you are developing.
