AjaxFileUpload Control using GridView to show uploaded files

I have spent about 2 days trying to figure out how to use the new AjaxFileUpload control along with a GridView to show what files have been uploaded.

My problem is that the GridView is not displaying the uploaded files until I reload the page.

I have both controls inside of an Update Panel.  I have tried adding an AsynchPostBackTrigger that uses the UploadComplete event:

<asp:AsyncPostBackTrigger ControlID="AjaxFileUpload1" EventName="UploadComplete" />

I have tried binding the gridview in the codebehind as the last step in OnUploadCompete method.

I have tried using a __doPostBack javascript function to force a Postback, triggered by OnClientUploadComplete, but that isn't working etiher.

What am I missing here?  The GridView updates when I use the controls within it (Delete), but does not automatically update after uploading a file using the AjaxFileUpload Control.  What gives?
