The grid is (hopefully) bound to a DataTable. If you expect what the user sees to change then you have to change that DataTable. Without knowing the specific details of your application, most likely Form1 should be passing that DataTable to Form2 so Form2 then makes the changes to that DataTable and then saves them from there to the database. That way, the changes actually show up in the grid before the database.

The whole point of data-binding is that the state of the UI and the data source is bound, i.e. changes to one are reflected in the other. If you want the UI to change then you have to change the data source. It's that simple.
