** Somwhere in your form
IF thisform.CheckForGrid(this)
   MessageBox("There is a grid")
ENDIF


*** Method CheckForGrid
LPARAMETERS loObject
LPARAMETERS lnFor
DO CASE
   CASE UPPER(loObject.BaseClass) $ [FORM PAGE CONTAINER]
        FOR m.lnFor = 1 TO loObject.ControlCount
            IF thisform.CheckForGrid(loObject)
               RETURN .t.
            ENDIF
        NEXT
ENDCASE
RETURN (UPPER(loObject.BaseClass) == "GRID")

Something like that, but not tested at all
