It's not the controlsource that'd doing it since it's a field. It's the record pointer of the alias that moves to EOF().
How you trap it depends on where the pointer gets moved to EOF().
Typically something like this is done:
Store the current record number before the process that moves to eof()
Run the process. (like a SCAN, SUM, COUNT, etc.)
Go to the recno stored previously.
