Hopefully someone can shed some light on these issues for me.

I have 3 states for my listitems (normal, clicked, highlighted) and would like these states to expand the entire length of the treeview control on mouse hover, selected, unselected.  I would also like to remove the expand buttons and have the treeview expand when a user clicks on the main item.  I found this example and thought there had to be an easier way for the treeview selection.  I hope there is!  Any help would be most appreciated.

The good news is that I got databinding working :)

A picture of my problems can be see here

Thanks in advance
Ryan

My xml is as follows:
<?xml version="1.0" encoding="utf-8" ?> 
<Scenes> 
  <Scene name="Test"
    <Procedures> 
      <Procedure name="Ryan" /> 
      <Procedure name="Rocks" /> 
      <Procedure name="AT" /> 
      <Procedure name="Photoshop" /> 
    </Procedures> 
  </Scene> 
  <Scene name="Test2"
    <Procedures> 
      <Procedure name="WPF" /> 
      <Procedure name="Is" /> 
      <Procedure name="The" /> 
      <Procedure name="Best" /> 
      <Procedure name="Language" /> 
    </Procedures> 
  </Scene> 
  <Scene name="Test3"
    <Procedures> 
      <Procedure name="Firefox" /> 
      <Procedure name="IE" /> 
      <Procedure name="And" /> 
      <Procedure name="Opera" />

Tina,

That example was worth the wait!  Thank you so much.  That was way better than the approaches I was taking.
Keep up the good work!
