I have to click on it a 2nd time, and then the dropdown remains open. Until I type anything, at which point it closes. So I have 2 quirks occurring so far with combos inside a grid...

>>>No, I did not try adding that code yet. I do notice that ***every other*** time I click on the combo's arrow, the dropdown list flashes for only a second, then disappears. If I click on it again, it remains open. So I do not think it has anything to do with the grid stealing focus away from combo (as the grid is already selected).

>>And why not? It's not a major system re-write to try it! By this process you'll come to realise why people end up using their own classes of the combo and not the bog-standard as you are seeking :-)

Still why not?

>Actually, I did insert a WAIT 'Combo1 GotFocus' WINDOW TIME 2 in the combo's GotFocus event - so I could see every time it got the focus. I believe the "flickering" problem is happening because the combo's initial value is blank - and not contained in the list. It's interesting to compare the behavior of an identical copy of the combo placed outside the grid. It behaves quite differently.

"plain wrapper", "common-all-garden"

Of course, creating your own combo-like object is always an option in a language as powerful as VFP. My perseverance does usually pay off for me in the long run. But I can understand that many others will not be as patient...

I guess many of us came to it already with dBASE III, Clipper, et al under our belts. It;s the converting to the OOP and visual bit that's the learning curve, but so pleasurable cf PPD.
