Word Add-in CustomTaskPane Scroll Problem RRS feed

  • Question

  • Hi!

    I'm working in an Add-in for MS Word, so in order to develop a more advanced user interface I decided to use WPF.

    I need to display a list of tags, so I'm using a ScrollViewer with an ItemsControl in it. This is my code:

       <ScrollViewer ScrollViewer.VerticalScrollBarVisibility="Auto" Grid.Row="2">
                <ItemsControl Grid.Column="1"                         
                  ItemsSource="{Binding Source={StaticResource tags}}"
                  ItemTemplate="{StaticResource tagTemplate}" 
                        <ItemsPanelTemplate >
                            <StackPanel Orientation="Vertical" />

    The problem is the mouse wheel scrolling is not working. Instead of scrolling the list, the scroll event is attached to the word document. When I scroll over the list it doesn't work, but if I click and scroll it works once, and then I need to click again. I think this is a focus problem, because the list is constatly loosing focus.

    Thanks in adavance for your suggestions.

  • Hi,

    I think I know what's is the problem wich is causing to lose focus. I have one MouseEnter and MouseLeave events on the items of ItemsControl (are defined in the ItemTemplate). 

    On MouseEnter and MouseLeave I have the following code:

    WPFContent.MyControlEventArgs ee = (WPFContent.MyControlEventArgs)e;
    Range range = this.addin.Application.ActiveDocument.Content
    Find find = range.Find;
    find.Text = ee.TagElement.TagText;
    find.MatchWholeWord = true;
    while (find.Found)
      range.HighlightColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdYellow;  find.Execute();

    so, basically the Find operation is causing to loose the Focus. 

    My question now is if it's possible to programmatically pass the focus to the ScrollViewer again.

    Thanks in advance!

  • Hi doaidag,


    Thanks for posting in the MSDN Forum.


    I think the “focus” you mentioned in the post means a range of the current document is it right?


    It’s based on my experience you need use Find.Found method again to back to the original position. If I have misunderstood anything, please feel free to let me know.


    Have a good day,

  • Hi Tom! Thanks for your answer!

    By focus I mean the currently active component. Imagine I'm scrolling the list in my addin, like I said. When the mouse events that I mentioned in the previous posts are fired, the scroll action starts scrolling the document and not the list.

    I treid to use the Find.Found method again but without success...

    Any oder ideia?

    Thanks very much for the attention!
