It's pointless to handle the Enter and Tab keys when there are lots of other ways for a user to commit a change to a cell's value. For example, they can click on another cell. Presumably you wish to have the database updated when they do one of these other things as well, not just when they press certain keys.

So instead of handling the KeyUp event, handle the CellValueChanged event. This event is raised whenever the user commits a change made to a cell's value, which typically occurs when focus leaves the cell.

As you point out, pressing Enter causes the focus to shift to the next cell in the column, while Tab causes the focus to shift to the next cell in the row, so this will work just fine in your case. It will also work when the user clicks on another cell using the mouse, or moves around to another cell using the arrow keys, or any of a number of other methods of committing a change.

When you handle this event, you will always get the correct row index and column index for the changed cell. This information is contained in the DataGridViewCellEventArgs object passed as the e parameter to the event handler method.
