Certainly. Assume I have a form (form1) with a grid on it and button. The form is called from the code snippet below

DO FORM form1
READ EVENTS

DEFINE CLASS custtest AS custom

FUNCTION DOSTUFF
SET DATASESSION TO 1

WAIT WINDOW "Custom object: Data session: " + ;
LTRIM(STR(SET('DATASESSION'))) TIMEOUT 1

SET DATASESSION TO 2
ENDFUNC

ENDDEFINE

The button click event has the following code in it.

LOCAL lnDataSession

WAIT WINDOW "FORM Data session: " + ;
LTRIM(STR(SET('DATASESSION'))) TIMEOUT 1

lnDataSession = SET('DATASESSION')

ocusttest = CREATEOBJECT("custtest")
ocusttest.dostuff()

SET DATASESSION TO lnDataSession

WAIT WINDOW "FORM Data session: " + ;
LTRIM(STR(SET('DATASESSION'))) TIMEOUT 1


If the code in the dostuff() method of the custom object is placed unchanged into the click event of the button the grid loses its data but because the code is contained within the custom object the grid works perfectly.
