title: WPF Treeview ShowRootlines
body: <p>Is there a way to show Root lines in a WPF Treeview?</p>
  
  <p>Or do you have to resort to doing something complicated like using Control Templates </p>
  
  <p>The Winforms treeview has a ShowRootLines property but none exists for the WPF treeview.</p>
  
  <p>Thanks</p>
