>>>I have a form with a two grids. The grids are both children of a controlling table whose records are displayed in textboxes.

>>>The second grid sometimes has a filter set based on the displayed records of the first grid which also has a conditional filter.

>>>When I'm scanning through the master table, everything is fine. I can turn the various filters on and off and both grids display properly.

>>Yes, you can reinitialize grid by:
>>cRecsource=Thisform.Grid1.recordsource
>>Thisform.Grid1.recordsource=""
>>Thisform.Grid1.recordsource=cRecsource
>>Sorry, I cannot give you more answers, because as you remember, I don't use temp relationships and prefer to use cursors (just because they are 'independent') as grid.recordsources.

I have to admit again, that I don't have much experience with SQL statement as RecordSource. I use cursor alias and it works perfectly, because once cursor is created, I can modify it (regardless other data) to accomodate 'unusual' grid behaviour which alas is not rare.
