title: Virtualizing WrapPanel for WP7
body: <p>I need to create a wrap panel with my facebook friends, meaning the itemcount is over 400, and it takes 5-10 seconds for all the items to load.</p>
  
  <pre><code>   &lt;ListBox.ItemsPanel&gt;
          &lt;ItemsPanelTemplate&gt;
              &lt;toolkit:WrapPanel/&gt;
          &lt;/ItemsPanelTemplate&gt;
      &lt;/ListBox.ItemsPanel&gt;
  </code></pre>
  
  <p>This code would be good, but it puts all the elements in 1 Row ...:</p>
  
  <pre><code>    &lt;ListBox.ItemsPanel&gt;
          &lt;ItemsPanelTemplate&gt;
              &lt;VirtualizingStackPanel Orientation="Horizontal"/&gt;
          &lt;/ItemsPanelTemplate&gt;
      &lt;/ListBox.ItemsPanel&gt;
  </code></pre>
  
  <p>Any ideas how to add item wraping to VirtualizingStackPanel or how to add Virtualizing to a WrapPanel:</p>
