    Is there a way to keep the item in the treeView when you drag it to the listBox?

    Hello Brian,

    You might want to check PreviewDragEnded event. If it is handled, the treeview will not remove items from its collection.

    Let me know if you have any other questions.

    ok i subscribed to the event, but i am unsure of what i would need to do in the event.  You have an example?
    private void inputTree_PreviewDragEnded(object sender, RadTreeViewDragEndedEventArgs e)
            {
      
            }

    Hi Brian,

    In order to make this work you need to add the following code:
    private void inputTree_PreviewDragEnded(object sender, RadTreeViewDragEndedEventArgs e)
            {
                 e.Handled=true;
            }

    That way when drag ends the tree will not remove the dragged items.
    Let me know if you need any further assistance.
