Actually, my objective is to have a thin column with a single character that indicates which record i'm on in the grid. I've already got a Grid property called nCurrRec which is being updated to reflect the current record. I need the funtion in my ControlSource so I can say something like:
IIF(RECNO()=THIS.parent.ncurrrec, "*", "")
So I can flag the actual record that I'm on

I HAVE looked at another way of indicating the current record by highlighting every column of the current record, but it takes too long.

Any other ideas?
