Please any suggestion, code samples, to avoid this situation are welcome ( in c#)

Use the Post-Redirect-Get (also known as Redirect after post) pattern. It simply consists in redirecting after a successful post, so that the user refresh results in an idempotent GET to be done rather than a POST. It has the additional advantage that the browser "forgets" about the POST in its history, which means the back button won't submit either.

Put a field in page call it status for example, after submitting first time it's populated with SUCCESS. If it is the do not save again.

Not the ultimate solution for sure.
