The title pretty much says it all. I have a project that for political reasons cannot be moved to a later version of .Net and would love to have a drop-in control for uploading files better than the old FileUpload control.
I'd like to use the AsyncFileUpload control, but it's not in the latest version of the toolkit that is supported in the 2.0 framework.
I've looked at some of the flash based controls, but integrating them would trigger a full regression test of the project I'm on (multiple weeks).
We've lived with the FileUpload control because our files are small, but the error handling when a file gets larger won't be unacceptable much longer.
-- EDIT --
I just found Uploadify. At first I didn't think it would work, but I checked out the forums any way. I found this link http://www.uploadify.com/forum/viewtopic.php?f=7&t=142&p=8620&hilit=asp.net#p8620 It works great. I can do whatever I want to in the upload handler.
