Ok. I'll try to remove the command button. About row buffering tha was my first solution, but the user wants to move within the grid in order to see other records and i can't know when he does in order to do the apropiated calculations to the record he is editing. I've tried beforerowcolchange but i dont know how to determine if the user is moving into other row or just into other column. I can know this with laskey if he does with the keyboard but not if he does with the mouse. Any idea ? Thanks.
