Validating on row save

Hi I have a databound grid and which has some validation on a number of the cells but I want to be able to check all the cells before the final save to the dataset. I can see there is a rowsaved call but this appears to be after the fact. a rowsaving would have been perfect but doesn''t look to exist. Can anyone advise as to what would be the best way to do this? Thanks Ross

Try RowLeave. This is a canceable event that is rasied before values are saved to the datasource.
