Obviously this is unacceptable code on a professional level, but if you're just playing around, it's a fine starting place. I believe executenonquery returns a number to tell you how many rows were changed by the query. Grab it and see if it's 0. Put a breakpoint before the redirect, and check your database at that point. If the data is there, then try to work out why your database gets reset.

And, do some reading up on how to properly structure a database driven project. This does look like code someone will use, I hope no-one is paying for it, but you may as well learn to make your own code maintainable also

Pay attention to what Christian told you. Your code is only good enough for playing around, and is not production quality code.

Beyond that, I don't see your connection string being set. You normally pass it as a parameter when you create your SqlConnection object. Also, if you put a try/catch around that block of code, you'll probably be able to tell what's wrong.
