I would like to disable the inputFile during the upload, soh the user will cannot "incidentally" starts a new upload, during a transfer. Is there any way to do that?
I've tried to used the "onClientClick" event on my submit button, but it wasn't fired anyway. I also had tried to hook the onsubmit function in the neatUpload.jas, but when I could disable the inputfile control, the upload suddenly stops.
I tried using OnClientClicked and ran into the same behavior you described. However, this behavior isn't specific to NeatUpload. A regular ASP.NET FileUpload or HtmlInputFile control will have the same behavior. I think browsers just don't upload files in disabled form controls. I think the other two options are the correct way to handle this issue.
