title: WPF TreeListView
body: <p>I was wondering if anyone knows how to use the <code>TreeListView</code> in WPF/XAML/Expression Blend. Without using the code behind.</p>
  
  <p>This what I want to do. I would like to populate a <code>TreeListView</code> with information, if the information's client and matter are the same, then just make that item a child of it.</p>
  
  <p>Example:</p>
  
  <p>Client 1= Kevin, Matter = Cook, Time =5
  Client 2 = John, Matter = Program, Time = 4
  Client 3 = Sam, Matter = Run, Time =9
  Client 4 = Kevin, Matter = Cook, Time=7</p>
  
  <p>The problem will look like this
  the - and + is the expansion of the tree list view</p>
  
  <pre>
  - Kevin Cook 5
         Kevin Cook 7
    John Program 4
    Sam Run 9
  </pre>
  
  <p>I am retrieving all the information from a database. My current problem is, I can't add a children into my treelist. I was wondering if anyone knows how to do this without hard coding?
   I looked into the <code>HierarchicalDataTemplate</code>, but there was not much information in it. Any help would be greatly appreciated!!!</p>
