You can use an Update trigger together with an error handling routine.

>I need to do a valid on a row change in a grid. I have two date fields in a record and I need to make sure the 2nd date is not before the 1st date. As it is now, if the user enters a bad date in the 1st column he has to enter a bad date in the 2nd column in order to get back to the 1st column. Any way to test both dates before leaving the row but allow the user to get to both columns? BeforeRowColumnChange() only uses the column number, not the row/record.
