Why does Lost focus does not retain focus ? by ramani
faq184-2559
Posted: 9 Oct 02 (Edited 9 Oct 02)

Often, we use validation code in the LostFocus event instead of in Valid event of a control. There are many reasons to do this way.

What one often forget is that - the lost focus event does not retain focus by the evnt returning .t. or .f. (example.. RETURN .t. or RETURN .f.)

The code should follow the example given below:

myText1.LostFocusEvent
**********************
IF This.Value # myDesiredValue
    MESSAGEBOX("Try again. Value not acceptable",16,"Stop")
    NODEFAULT
ENDIF

The use of NODEFAULT tells the event not to loose the focus and retain it back.
