You could add a property to the form, let say Foo. In the InteractiveChange event, you assign .T. or .F. to this property. Then you could put this code in the LostFocus:

IF ThisForm.Foo
   NODEFAULT
ENDIF

>Is there a way to assign code to the LostFocus of an object during runtime? I have a conditional statement that I want to use in the InteractiveChange method that would set the LostFocus to "NODEFAULT" or "" depending
