  When I go to upload an excel file that I have open on my desktop, it errors somewhere in the javascript with a generic error. I have some .Net code to test if the file is open. However, I do not know where to call it. I tried OnClientFileSelected with no luck.

  Hi Herbert,
  
  This is a known limitation of the Silverlight module that RadAsyncUpload uses, whenever there's Silverlight available. To fix this, you have to disable Silverlight for RadAsyncUpload:
  

  <script type="text/javascript">

      Telerik.Web.UI.RadAsyncUpload.Modules.Silverlight.isAvailable = function () { return false; }

  </script>
