Hi
I have a page which has a UserControl, and within the Usercontrol I have a RadUpload with a RadUploadProgressHandler control. I can upload files without any problems, and the progress handler displays as it should. However, after uploading a file, if I wait a few minutes and then make another ajax callback on the page with a different control, I get the error "RadUpload Ajax callback error. Source url returned error:12029 .. Unknown... Did you register the RadUploadProgressHandler in web.config?" . Which is a bit strange because I have already done the file uploading and the action which triggers this error message has nothing to do with file uploading!
I am using version Q2 2010.
Any help would be appreciated
Thanks
