Today i got a mail from client, says that "File Upload functionality not seems working."
I went to site and find out.
"AJAX AsyncFileUpload control not access-able, It was enabled false"
i knew, Problem not made by me, it from somewhere. After plugging my hair for an hour, got this solution.
Problem not comes from CSS, Script or Code Behind,
Problem was, i`m using AJAX control tool kit version 3.5.40412.2, This one not up-to-date, It having errors with IE9.
Download Latest version of Ajax Control Toolkit Or use the below one.
The new release solved my AsyncFileUpload problem with IE 9.
