title: How to style a treeview in Expression Blend
body: <p>(Using Expression Blend 4 RC, Silverlight 3)</p>
  
  <p>I have a treeview with several different item templates for different levels. When I open this project in Blend, it seems I can only really style the top-most DataTemplate (via right-click the TreeView in the Objects/Timeline view, Edit Additional Templates->Edit Generated Items (ItemTemplate) -> Edit Current).</p>
  
  <p>How do I drill down into the level I want and edit those templates?</p>
