The file upload control does not retain the posted file with each request.
When the user selects a file, it will be available in the next PostBack request that occurs.

You should check for a PostedFile on each postback and save this file on the server.
Keep a reference to its path in the ViewState.
Then you can process the file when the user has finished all inputs.
