title: WPF TreeView and Checkbox
body: <p>How would someone go about adding check boxes to only the children of a tree view in XAML?  My goal is to have a tree view where the parent is just a text block and all the children are check boxes but only one child can be checked at a time.  I have no problem making the whole the tree view check boxes but I am not sure how to get what I really want  Any suggestions?</p>
  
  <p>Thanks.</p>
