while you click the upload button check the path for null?
Also, submit your code to resolve the issue what I can?...

Adding a postback trigger usually is sufficient as file can not be uploaded from within an update panel. You will have to post your code to show how you are handling uploading of file and in which event.

Do Not Use FileUpload Control Inside Update Panel.

FileUpload control needs a full postback to get it worked. Add a PostBackTrigger for the control . This should work for you.
