title: Bind to a listbox, but only show the selected element?
body: <p>I have a collection of objects which I bind to a ListBox, but I actually only want to display the selected element, and not the entire collection.  What's the best way to go about this?  Use a different control?</p>
  
  <p>I think I can do a Visibility ValueConverter which checks the IsSelected attribute -- and if not selected collapses... but I'm still interested in other ideas.</p>
