Question : Put control inside of AJAX UpdatePanel, now get Type 'System.Web.UI.UpdatePanel' does not have a public property named 'FileUpload'

I just added the UpdatePanel to a form. Now it complains about the FileUpload that was there before, but is now inside the UpdatePanel.

I did add the ScriptManager to the form.

I just checked, and the AjaxContorlToolkit is one of the references.

What did I mess up?

Thanks!

Looks like I was missing the ContentTemplate. The attached version compiles.

Thanks for looking!
