Hi everyone...I'm facing the following problem. I have an update panel where i have a multiview. One of the view is used to upload a file. I have a cmdUpload button. FileUpload.HasFile always returns false. I've read a few threads here about this issue and it is said that I have to add cmdUpload as a PostBack Trigger because Ajax does not allow Async uploads. I got an error by doing so that says that cmdUpload could not be registered neither as a PostBackTrigger nor as a AsyncPostbackTrigger due to confilcts. What is really strange is that I remove from design code my updatePanel just to test it, and i'm still getting HasFile=false...I used this control before and never had a problem without an updatePanel.Any suggestion?Thanks!
