Hello,

Here are two very thorough walkthroughs on doing just this:

If you can get the data from the database, to the page, then the reverse operation follows a very similar pattern. You would have methods on your DAL that inserts/updates the data in the database. Your BLL would call these methods once they have worked on the data to make it correct, and your UI would call the methods on your BLL based on the information that is posted to the web form.
