how to capture the enter even in alv

[Former Member]

hi, experts

my requirement is that:

i create an alv ,set it response to the enter even, if the content has changed, a class will be response it .

the code like below:

CALL METHOD g_grid->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_enter.

CREATE OBJECT g_event_receiver.

SET HANDLER g_event_receiver->handle_data_changed FOR g_grid.

but if the alv content has no changed, nothing will be happen, i want to do something such as popup a message even if the content has not changed and user press enter.

I don't think this is possible.

may be you can do is

during the enter key is pressed

    call method cl_gui_cfw=>set_new_ok_code
             exporting
                 new_code = 'DUMMY'.

and in the user command

 if ok_code eq 'DUMMY'
    call method g_grid->check_changed_data
      importing
        e_valid = v_valid.
    if v_valid ne c_x.
      call function 'POPUP_TO_CONFIRM'
        exporting
          titlebar              = text-025
          text_question         = text-026
          text_button_1         = text-027
          text_button_2         = text-028
          display_cancel_button = ' '
        importing
          answer                = v_answer.
endif.
