Thank you for the clarification. Is your D ataGridView bound to the data or are you filling the control using code that you wrote? The solution depends on the answer. If I give you an answer but it is not for the way that you are doing things then it would be a waste of your time and my time. Are you using the Entity Framework or a TableAdapter or a SqlDataAdapter or what? A simplified answer is that you simply need to create an update SQL command.
