SQL and windows form problem

[reverend]

I have several textboxes associated or bound to sql. Some of the textboxes are accepting data some are not. If I put a number in the ones that are not working, they accept the data. But if I enter anything other than a number, they do not. All fields in the database are set to nvarchar(50). Any thoughts?

Thanks in advance

Edit: I found the issue. I had made some changes to the database a while back and the dataset didn't get updated. Mods/admins, feel free to delete this thread.
