title: 3rd Party WPF Treeview Control
body: <p>I am wondering if anyone knows of a WPF control that can serve the following functions.  </p>
  
  <ol>
  <li>Is a treeview that contains treenodes</li>
  <li>Can display different numbers of treeviews depending on how wide the parent window is expanded</li>
  <li>Can be bound with an ItemSource</li>
  </ol>
