I disagree. You can try for yourself and see what happens. The problem is often that people don't know how to do things because they don't look to see what's available to them. Have you explored the DataSet designer to see what it can do? I'd wager not. It's not going to read your mind and jump out at you with the information you need. You have to go looking for it. That is exactly how I learned so much of what I know and it also has the advantage of exposing you to things that you may not need right now but will come in handy later. If you'd explored the DataSet designer when you first started using it then you wouldn;t be asking this question now because you'd already have found that information. You don't have to sit and wait for information to come to you. You can go and look for it. You can do that with a test project first, to get a handle on the principles before applying them to your working project, or you can take a backup of your working project and then experiment on it directly, knowing you can fall back to a working copy if you break it.
