title: Hierarchical DataGrid?
body: <p>Are there any free user controls that offer a WPF DataGrid with the ability to have multiple children (should be a way of representing XML)?</p>
  
  <p>What I want is a sort of TreeView with the ability to show an 'item name' column and 'item data' column that is user editable.</p>
  
  <p>Are there any free user controls that can provide me with that?</p>
