title: How to make ContinuumNavigationTransitionInfo.ExitElementContainer work on a universal app
body: <p>My understanding is that an Exit element "flys out" of the page on transition and the Entrance elemnent "flys in". I am able to get the "fly in" transition to occur, but not the "fly out" from a listview:</p>
  
  <p>Here's my list - when I click an item nothing happens. I am not even sure what elements to play with to try and get it to work - there's very little documentation:</p>
  
  <pre><code>&lt;ListView ItemsSource="{Binding}" ContinuumNavigationTransitionInfo.ExitElementContainer="True" ItemClick="ListView_ItemClick" IsItemClickEnabled="True" Grid.Row="1"&gt;
      &lt;ListView.ItemTemplate&gt;
          &lt;DataTemplate&gt;
              &lt;Border BorderBrush="Blue" BorderThickness="2" ContinuumNavigationTransitionInfo.IsExitElement="True"&gt;
                  &lt;TextBlock Text="{Binding}"/&gt;
              &lt;/Border&gt;
          &lt;/DataTemplate&gt;
      &lt;/ListView.ItemTemplate&gt;
  &lt;/ListView&gt;
  </code></pre>
  
  <p>And here's my second page (which does "fly in"):</p>
  
  <pre><code>&lt;Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"&gt;
      &lt;TextBlock Text="sdfsdfsdfsdf" VerticalAlignment="Center" HorizontalAlignment="Center" ContinuumNavigationTransitionInfo.IsEntranceElement="True" Tapped="TextBlock_Tapped" IsTapEnabled="True"/&gt;
  &lt;/Grid&gt;
  </code></pre>
