title: WPF ListView Show selected item
body: <p>I want to show the selected item in a list view automatically(it isn't possible to show all items without scrolling).</p>
  
  <p><code>this.listView.SelectedIndex = 999;</code> selects of course an item, but it doesn't show it.</p>
  
  <p>what can I use to show it automatically ?</p>
  
  <p>kind regards, jeff</p>
