title: WPF & Telerik RadTreeView: How do I intercept the ItemSelected event on drag?
body: <p>I have a Telerik RadTreeView. </p>
  
  <p>I am using the ItemSelected event to open a detail view for the selected item.</p>
  
  <p>I am using the Drag and Drop functionality to do as you would expect, rearrange the hierarchy of items in my tree. Nothing special.</p>
  
  <p>The problem comes that when I click to drag the item in my tree, it opens the detail view for that item because the ItemSelected event is fired. Is there a point at which I can tell that an item is being dragged prior to the ItemSelected event being fired so that I can cancel or intercept the ItemSelected event and prevent the detail view from being displayed?</p>
