I accidentally posted this in the Upload forum, not AsyncUpload, so I am reposting it. This used to work, but we recently changed environments and I am not sure where to check for problems.
As soon as the user selects the file to be uploaded, a temp file is created based on the name of the upload in App_Data/RadUploadTemp. But then a postback happens, the file is removed from RadUPloadTemp, but it not moved into the UploadedFiles folder. This happens on a production server as well as locally. I have set permissions on the folder to full control. Tried Chrome, IE, FireFox and got the same results. The OnClientUploadFailed event is not firing. The OnFileUploaded even is firing. What am I missing?
