Hi All

I am making a project in .Net. I have a problem related ADO.Net.
I hav 2 related tables by primary and foreign keys.
When I add new data 2 the second table it adds in the data set but throws error when I attempt it to save permanently in SQL Server (backend).
I am doing this using ...

I need to use our "Password" and not the "user name" to login, did you pay attention to that?
