Handling the Standard Toolbar Button click of an ALV

Question

Hi Experts,
I have created an ALV grid output using CL_GUI_ALV_GRID with standard buttons(default) on the toolbar. When I click on any of these standard buttons, say '+' button to insert records, my custom program is not hit.
I know there is a protected event 'TOOLBAR_BUTTON_CLICK' which I tried to handle in my program but it did not work. However, I am able to handle the public event 'DOUBLE_CLICK' of the same class 'CL_GUI_ALV_GRID'.
So..can anyone tell how to handle this protected event OR how to handle the STANDARD buttons on ALV toolbar so that they hit my custome code.
Thanks very much.
Regards,
Rudresh

Hello Rudresh
The point is to "re-define" the standard ok-codes of toolbar buttons:
" Make toolbar interactive
CALL METHO go_grid->set_toolbar_interactive( ).  " raises event TOOLBAR
" Event handler method
METHOD handle_toolbar.
* define local data
  DATA: ls_button    TYPE stb_button.
" Redefine function code
  LOOP AT e_object->mt_toolbar INTO ls_button
                  WHERE ( function = cl_gui_alv_grid=>MC_FC_LOC_INSERT_ROW ).
    ls_button-function = 'MY_FCODE'.  " triggers USER_COMMAND
    MODIFY e_object->mt_toolbar FROM ls_button INDEX syst-tabix.
  ENDLOOP.
ENDMETHOD.
