title: Wait cursor till UI is ready. How to?
body: <p>I have a ListView with several hundred complex element. When the collection that is bound to the ListView has been filled with data it takes several seconds till the UI becomes responsive. My wait cursor turn back to regular once the collection is filled, but I would like it to stay in wait till the UI is responsive. I'm not sure what's going on in the background but I guess the WPF elements are initialized. Is there an event I can wait for till WPF is done with its updating?</p>
  
  <p>(It's fine for the user to wait as long as a wait cursor it shown.)</p>
