title: WPF ListBox Scroll to end automatically
body: <p>In my application, I have a <code>ListBox</code> with items. The application is written in WPF.</p>
  
  <p>How can I scroll automatically to the last added item? I want the <code>ScrollViewer</code> to be moved to the end of the list when new item has been added.</p>
  
  <p>Is there any event like <code>ItemsChanged</code>? 
  (I don't want to use the <code>SelectionChanged</code> event)</p>
