How to determine the XamTreeItem clicked?
posted

I have a WrapPanel that contains 5 XamTrees.  I want to be able to get a reference to the XamTreeItem that was clicked.

My first attempt was to set a MouseLeftButtonUp event handler on the WrapPanel and use e.OriginalSource to get the reference to the XamTreeItem.  But, instead, e.OriginalSource returned the TextBlock associated with the XamTreeItem.

Am I going to have to programmatically subscribe to the event for each and every XamTreeItem?  Or, is there a more elegant and efficient way to handle thie?

    Hello,

    You can walk the visual tree to get the XamTreeItem:

    TextBlock tb = (TextBlock)e.OriginalSource;

    DependencyObject dob = VisualTreeHelper.GetParent(tb);

     

     

    while (dob.GetType() != typeof(XamTreeItem))

     

    {

      dob =VisualTreeHelper.GetParent(dob);

      if (dob == null)

        break;

    }
