Hi Joao,
There is a known bug in grid.control.valid and !corrected on VFP6 too as MS knowledgebase says. A controls valid is not fired if you click outside the grid (in fact fired but but acts as not fired and you can go outside of grid). Workaround :
-Create a custom property (form or grid - say form) lHangingValidation
-Control.interactivechange (which has valid code also)

*InteractiveChange
* Your actual validation code here except messagebox etc
thisform.lHangingValidation = (this.value > 1000) 
&& Expression is what valid would return .f.

* Grid.Valid
return thisform.lHangingValidation

Probably you won't need lostfocus then.
