I added an AsyncFileUpload control to a working page with UpdatePanel. It seemed to do nothing. Upon debugging, I noticed that FileUpload1.HasFile() was always False, even when a valid file was just selected. On a whim, I removed UpdatePanel, and now FileUpload1.HasFile() was working properly. Unfortunately, I lost UpdatePanel functionality.
Anyone know if there is a way to get AsyncFileUpload to work from within UpdatePanel?
Much appreciated.
