View 1 RepliesI'm trying to use below simple code for ajax postback. With file upload, neither javascript the "function startRequest" ever triggers, the file control shows null value somemore.Earlier I had Update progress which didn't work with file upload ever so I removed it. Now I just want to disable the button as the file is uploaded and its inputs are processed in the background. Once the response comes back, the "submit" button is re-enabled.But the file-upload with Updatepanel doesn't work at all. What am I doing wrong,
