Answer 1

Hitting refresh is actually the same as clicking the button to insert data again. Your button click event should probably redirect the user to a new page.

Answer 2

Apparently you're using something called "RefreshProtectModule" which does not allow refresh. On one hand that's good - otherwise your form would insert record into DB on every refresh. On the other - you have to handle the "Refresh detected" exception and handle it graciously.
