EXPLANATION

This is the issue which normally occurs with Fileupload control. Your FileUpload control will not have the image path because your file upload control is in the UpdatePanel. When you run the program your UpdatePanel will send request to the server and that request will be send to the ajax therefor file upload control will not triggered and not work as expected.

ANSWER

You need to remove your FileUpload control and place it out side the UpdatePanel. Then it will work as expected. I hope this information will be useful to you.

Have a great day.!
