I'm trying to determine the PK of the record displayed at the top of a continuous subform.
I have a subform which contains times from 07:30 - 17:00 in 15 minute intervals. Unfortunately, I can only display about 20 of these records at one time, so I have the vertical scrollbar enabled. If the user scrolls down, using the vertical scroll bar, I want to be able to determine what time interval is locate at the top of the visible section of the subform.
I know that if the user scrolls down and then selects the top most record, I can use the SelTop property of the form, but this value does not change unless the user actually selects the record at the top of the form. Any ideas:
1. What event to use to check whether the user has scrolled down
2. how to determine the time associated with the record displayed at the top of the form.
