You can't do this for security reasons, if the control kept its filename then that would mean you could set a default filename, and if you could set a default filename then malicious websites could trick you into uploading known files. There's no point asking if there is a way around this as if there was a way around it then malicious sites would use it. Instead you need to re-architect how your page works such that you don't need to maintain the file upload state. For example if the postback is to add new upload controls then you could add the new controls via javascript to avoid the postback, or add say 10 upload controls but hide 9 and then rather than add new controls you simply show one of the hidden ones and so on.

Or you split your process in two so they do everything that doesn't involve file uploads, and then in a second stage do the file uploads.

Apr 23, 2013  Hi, I have fileupload control in webpage and couple of control with autopostback true, if you select a file in fileupload control and page postback with postback control then file upload control lose the selected file.
