title: Binding to the DataContext of the Item in the ItemsControl
body: <p>How can I bind to the Item's DataContext in the ItemsControl from within a nested data template (a data template of a control within the item's data template)? </p>
  
  <p>I can't use <code>TemplatedParent</code>, because it's double templated.
  And I can't figure out how to use <code>FindAncestor,AncestorType</code> because I don't know what the type is for each Item.</p>
  
  <p>Any idea?</p>
