CL_GUI_ALV_GRID DATA_CHANGED event E_UCOMM

[Former Member]

Hi,

At the ALV event handler DATA_CHANGED, I want to capture the user command on the screen other than the alv toolbar. But E_UCOMM holds nothing when I press a button on the screen. How can I capture screen function code?

Best regards,

ts

Hi,

  Have you declared function code in the PF-status of the screen.

Hi,

Below are the steps to achieve this functionality. you have to handle the event to catch the ucomm

1. Register the event:

*--for tab   

     CALL METHOD go_alv->register_edit_event

         EXPORTING

           i_event_id = cl_gui_alv_grid=>mc_evt_modified.

*-- for enter

       CALL METHOD go_alv->register_edit_event

         EXPORTING

           i_event_id = cl_gui_alv_grid=>mc_evt_enter.

2. Get the changed row,with this below code your changed data row will be selected :

     CALL METHOD go_alv->check_changed_data.

3. Handle the event:

     SET HANDLER go_respond_events->handle_data_changed_finish FOR go_alv.

4. You have to create the class for this before. In this class you have to update that value:

CLASS respond_events DEFINITION FINAL .

   PUBLIC SECTION .

     METHODS: handle_data_changed_finish FOR EVENT data_changed_finished

              OF cl_gui_alv_grid.

ENDCLASS .                    "respond_events definition

CLASS respond_events IMPLEMENTATION .

   METHOD handle_data_changed_finish.

     LOOP AT <your intarnal tablewhich used for display> INTO <ls_>.

      **jwrite your code here

     ENDLOOP.

   ENDMETHOD. "handle_data_changed

ENDCLASS .               "respond_events implementation
