WebFileUploaded doesn't work in Update Panel

I've created a very simple page that has a WebComboBox, a button that posts-back, and a WebFileUploader, which is inside an update panel. Before the page posts-back, the Uploader control looks and works correctly.  But, after the button submits the page, the WebFileUploader is not completely redrawn (the checkbox, filename textbox and the 'Select' box are missing - only the 'Upload now' button is displayed).  This is preventing the user from uploading a file.


What am I doing wrong?

I'm trying to create a page where the user will pick a product from the WebCombo, click the 'PartLookup' button, and have the update panel display info for the product and allow the user to upload new photos for that product.

Thanks for the help,

Jim

P.S.   ASP.NET version 4.0, and using Visual Studio 2010
