If the focus is moved to a cell in the same row, then no other events occur.
If the focus is moved to a cell in another row, then both Row Validating and Row Validated are fired, containing the whole row data, including the new and the old values of the edited cells.
The validation events are meant to support the data validation of the user input.
They occur when the new content entered by the user is about to be committed.
