Do you mean in VFP?

There you can Return .F. in the valid too.
You can also issue NoDefault in the LostFocus Event.
It is the same for all objects.
But look out for the Grid.
There the object in the grid loses the focus after in the grid valid event fires.
So you can have that in the control in your grid you don't allow the user to move out the grid, and in the grid you have already allowed it.
You can workaround this by calling the control's valid event in the grid's valid event.
