The code behind is the same, that's why I want it as a 1 control only with 2 templates. What I'd like to do is to be able to define these 2 templates wi...
It seems that others have had variations on this question, but from what I can tell it hasnt been addressed for folks using collections in a single view model.

Hi, Is it just me? I’m a WPF newbie. Everything is nice and shining, and I managed to write a small application that meets my needs, but I noticed that many times, for instance when I click a button or a list view, the event is handled (e.g. list view selection is changed), but the area under the mouse is not updated, so a small rectang...
I was looking for a way to change an Image during a storyboard, or more specifically, change the Source property of the image to point to a new image resource.

I copied the xaml from Aero dic...

The problem I'm running into is that the event handler fires on the TreeViewItem (node) that I click on with the mouse, and then it continues to bubble up the control tree, even though I've set e.Handled = true on the RoutedEventArgs provided...
I handle commands inside a RoutedCommand class that implements RoutedUICommand. This would help me to block or override a command by checking their CanExecute and Execute if needed.
