I'm developing a website using .NET 3.5 and I'm having problems with the asyncfileupload control.
The problem occurs when you upload a file, and then try upload the same file again. On the second upload, none of the clientside nor serverside methods fire. Everything works fine if you upload one file, upload a file with a different name and then upload the first one again.
This is a bit of a pain because on the page I allow the user to delete the uploaded images so I need the functionality to upload a file with the same name as the previous upload.
Has anyone else encountered this and are there any work arounds?
