In a grid, I use code in the AfterRowColChange. You can base the condition on whatever you want. Also you do not need and IIF() if the expression evaluates to logical:

This.ReadOnly = CondExpr && OK if CondExpr evaluates to a logical value
This.ReadOnly = (ThisForm.optionGroup.Value = 1) && also OK

I can not really give you a definitive answer because there are so many possibilities available to you for just about any situation you can come up with.
