title: ScrollViewer Issue with StackPanel in Windows Phone 8
body: <p>I put StackPanel into ScrollViewr, When scrolling to last item it returns back to its old position.</p>
  
  <pre><code>&lt;ScrollViewer Margin="0,0,0,20"&gt;
  &lt;StackPanel&gt;
    //Textblocks and Textboxes ...
  &lt;/StackPanel&gt;
  &lt;/ScrollViewer&gt;
  </code></pre>
  
  <p>After search i found that:
  <a href="https://stackoverflow.com/questions/1576623/itemscontrol-virtualizingstackpanel-and-scrollviewer-height?rq=1">ItemsControl, VirtualizingStackPanel and ScrollViewer height</a></p>
  
  <p>I changed my code to:</p>
  
  <pre><code>&lt;StackPanel&gt;
    //Textblocks and Textboxes ...
  &lt;/StackPanel&gt;
  &lt;ScrollViewer&gt;
  &lt;VirtualizingStackPanel /&gt;
   &lt;/ScrollViewer&gt;
  </code></pre>
  
  <p>I can't set CanContentScroll="True" as i can't find it.
  Also  make exception:
  System.InvalidOperationException: A VirtualizingPanel is not nested in an ItemsControl. VirtualizingPanel must be nested in ItemsControl to get and show items.</p>
  
  <p>What must i do, to enable scrolling without returning back to its old position?</p>
  
  <p>Regards,</p>
