Wow! That caused a great deal of interest! For further explanation, the following code is in the base class that is being subclassed onto the form

IF TYPE('THISFORM.pcSecRights')= 'C' AND THISFORM.pcMode <> 'A'
RETURN .F.
ENDIF

I want to add the following code to the When event of the textbox once it has been instantiated:

IF !DODEFAULT()
RETURN .F.
ENDIF

IF THISFORM.pcMode = 'A' AND EMPTY(THIS.VALUE)
THIS.VALUE = THIS.Parent.PickField1.Value
ENDIF
