title: Prevent or Capture MouseWheel scrolling on DataGrid
body: <p>I'm trying to capture the mousewheel event on a Silverlight 4 DataGrid. The problem is that whenever the mousewheel event is handled by the DataGrid the MouseWheel event does not fire. But when the DataGrid is at the top and I try to scroll upwards I get the MouseWheel event and the same thing at the bottom - i.e. the event is fired when the DataGrid does not handle the MouseWheel event itself.</p>
  
  <p>I've also tried to capture the mousewheel event on the vertical ScrollBar (the Silverlight DataGrid does not use a ScrollViewer)</p>
  
  <ol>
  <li>How can I prevent the scrolling?</li>
  <li>If I don't prevent the scrolling - how can I capture the event in all scenarios?</li>
  <li><p>Can I capture MouseWheel events even though I haven't focused the DataGrid yet (the event does not fire and the scrolling does not work before focusing the DataGrid)? Or should I use the following events:</p>
  
  <p>HtmlPage.Window.AttachEvent("DOMMouseScroll", OnMouseWheel);
  HtmlPage.Window.AttachEvent("onmousewheel", OnMouseWheel);
  HtmlPage.Document.AttachEvent("onmousewheel", OnMouseWheel);</p></li>
  </ol>
  
  <p>Any help appreciated. Thank you.</p>
