Sergey,

The users can either maintain individual tickets or ticket books depending on which list last had focus. If the user wishes to delete 5 tickets then they can pick those 5 tickets and delete them all at once. If the user wants to delete 5 ticket books (or 50 tickets) then can click on the ticket book list, select the 5 ticket books and then delete them all at once. When the uses select more than on ticket book, then the ticket list becomes meaningless. In retrospect, a grid for the ticket book list would probably have worked better.

Thanks.

>>Yes. I have maintenance routines that act on ticket books selected by the user. What surprises me is that when will fire on every change of the row but valid will not. This would have been easy if valid would have unselected the row and when selected it. Thanks for all your help Sergey.
