Have a look at this article. This should help you out in handling the issue you are facing: Refresh Page Issue in ASP.Net[^]

This is one of the various ways it was done. Others could be to verify the data entered last, compare and prompt before moving ahead.

Sorry! but I don't agree with the solution. Page refresh follows the exact same route. Further, it's a button click event that is being triggered and will trigger again if refreshed. Putting it in IsPostback would not help. You can try that out.

You can use one of following solutions to solve this problem
1. After Upload is sucessfull. Response.Redirect to same page.
2. Use Javascript to disable F5 and right click.(User can still refresh from toolbar/menubar)
3. Use hiddenfield to check whether request came from buttonclick or refresh button
