How to refresh an internal table using ALV OO

Its really simple, all you have to do is register the enter and modified event before calling the method set_table_for_first_display( ).

or without registing those events just do this: CALL METHOD go_grid->check_changed_data

code:


CALL METHOD go_grid->register_edit_event
EXPORTING
i_event_id = cl_gui_alv_grid=>mc_evt_modified
EXCEPTIONS
error = 1
OTHERS = 2.

CALL METHOD go_grid->register_edit_event
EXPORTING
i_event_id = cl_gui_alv_grid=>mc_evt_enter
EXCEPTIONS
error = 1
OTHERS = 2.

p.s.: To refresh the ALV OO go_grid->refresh_table_display

How to use ALV with objects (example)

PROGRAM TEST.
DATA: OK_CODE LIKE SY-UCOMM,
GT_SFLIGHT TYPE TABLE OF SFLIGHT,
G_CONTAINER TYPE SCRFNAME VALUE 'BCALV_GRID_DEMO_0100_CONT1',
GRID1 TYPE REF TO CL_GUI_ALV_GRID,
G_CUSTOM_CONTAINER TYPE REF TO CL_GUI_CUSTOM_CONTAINER.
*---------------------------------------------------------------------*
* MAIN *
*---------------------------------------------------------------------*

SELECT * FROM SFLIGHT INTO TABLE GT_SFLIGHT.

CALL SCREEN 100.


*---------------------------------------------------------------------*
* MODULE PBO OUTPUT *
*---------------------------------------------------------------------*
MODULE PBO OUTPUT.
SET PF-STATUS 'MAIN100'.

IF G_CUSTOM_CONTAINER IS INITIAL.

CREATE OBJECT G_CUSTOM_CONTAINER
EXPORTING CONTAINER_NAME = G_CONTAINER.


CREATE OBJECT GRID1
EXPORTING I_PARENT = G_CUSTOM_CONTAINER.

CALL METHOD GRID1->SET_TABLE_FOR_FIRST_DISPLAY
EXPORTING I_STRUCTURE_NAME = 'SFLIGHT'
CHANGING IT_OUTTAB = GT_SFLIGHT.

ELSE.
CALL METHOD GRID1->refresh_table_display.
ENDIF.

ENDMODULE.
*---------------------------------------------------------------------*
* MODULE PAI INPUT *
*---------------------------------------------------------------------*
MODULE PAI INPUT.
* to react on oi_custom_events:
call method cl_gui_cfw=>dispatch.
CASE OK_CODE.
WHEN 'EXIT'.
PERFORM EXIT_PROGRAM.
WHEN OTHERS.
* do nothing
ENDCASE.
CLEAR OK_CODE.
ENDMODULE.
*---------------------------------------------------------------------*
* FORM EXIT_PROGRAM *
*---------------------------------------------------------------------*
FORM EXIT_PROGRAM.
* CALL METHOD G_CUSTOM_CONTAINER->FREE.
* CALL METHOD CL_GUI_CFW=>FLUSH.
LEAVE PROGRAM.
ENDFORm.
