title: How can I detect reaching the end of a ScrollViewer item (Windows 8)?
body: <p>I need to do some work when the user scrolls to the end of a ScrollViewer in a Windows 8 'Metro UI' app that uses .xaml with C# behind-code. Alternatively, the ScrollViewer has snap-points enabled, so detecting a "snapping" event will also work.</p>
  
  <p>Thanks</p>
