I am trying update a record in the database in one of the methods of GridViewControl. It is raising OptimisticLockException. In my database I have four date fields (dZadOpenDateTime, dZadCloseDateTime,dCreatedDateTime,dChangedDateTime) show in this picture http://imageshack.us/photo/my-images/854/exception.jpg/
Can you give me some hint how to handle this exception.
