Allan,
Just tried with a formset in 2 forms with having one grid each. It's working. I only used thisformset.lHangingValidation instead.
PS: To enforce I also used an expression in interactivechange (actually I never use valid for validation) :
thisformset.lHangingValidation = !(this.Value is valid)

>>>I am having a problem with a valid clause of a text box in a grid returning .f. but allowing the control to lose focus. Here is the scenario:
>>>
>>>The form (contained in a formset) has a grid with three text boxes. On the same form there are some command buttons. If I enter invalid data in the text box a message box with an error message is displayed, I return 0 and the focus remains correctly in the text box. If I then click on one of the command buttons, the command button gets the focus, my message box about the invalid data is displayed and then the command button incorrectly gets the focus.

>>>I have spent many hours on this problem and I would appreciate any assistance.
>>>TIA.
