BEFORE_USER_COMMAND problem

Former Member — Fri, 16 Jun 2006 09:11:20 GMT

Hi All,

i am using BEFORE_USER_COMMAND event of CL_GUI_ALV_GRID class.

But there are standard button that can't be captured in that event. The buttons are:

1. MC_FC_LOC_COPY_ROW (duplicate row button)

2. MC_FC_LOC_DELETE_ROW (delete row button)

etc...

could you help me how to capture this button before executed ?

Thank you in advance.

Sandi

Hi Sandi,

I'm not sure but the before_user_command event doesn't work with standard buttons.

Once I solved this problem making a custom button with the some fcode of the standard one; i.e you can create two button with fcode

1. MC_FC_LOC_COPY_ROW (duplicate row button)

2. MC_FC_LOC_DELETE_ROW (delete row button)

and try to catch now they with the event.

Bye

Hi,

COPY button, and Delete row , append row these buttons they don't link to BEFORE_USER_COMMAND .

they are used to make the changes to the Grid so using the below things you can trigger the DATA_CHANGES event, but not the BEFORE_USER_COMMAND event.

CALL METHOD G_GRID->REGISTER_EDIT_EVENT
EXPORTING
I_EVENT_ID = cl_gui_alv_grid=>mc_evt_modified.

CALL METHOD G_GRID->REGISTER_EDIT_EVENT
EXPORTING
I_EVENT_ID = cl_gui_alv_grid=>mc_evt_enter.

Hi Vijay,

Thanks for your reply,

When we put DATA_CHANGES, all the last cursor position & last scroll position has been changed.

I want to save the cursor & scroll position before process of double row is executed. Actually I want to override CLICK_ROW_COL in CL_GUI_ALV_GRID class that I have inherited.

Do you know how to do that ?

Thanks,

Sandi

Hi Sandi,

in the event data_changes you can get the row position and column position.

for reference you can see the Program <b>BCALV_EDIT_04</b>

this is for delete and append rows.

check this ..

line#161

  method handle_data_changed.
*
    data: ls_good type lvc_s_modi,
          l_price type s_price,
          ls_new type lvc_s_moce.

    error_in_data = space.

* check if there exist double entries
    call method check_double_entries( er_data_changed ).

* remember new or deleted lines for saving
    call method update_delta_tables( er_data_changed ).

* check mt_good_cells semantically
    call method perform_semantic_checks( er_data_changed ).

    if error_in_data = 'X'.
      call method er_data_changed->display_protocol.
    endif.

  endmethod.

Regards

Vijay

Hi,

I created a nice work around...

CLASS lcl_event_handler DEFINITION.

handle_toolbar

FOR EVENT toolbar OF cl_gui_alv_grid

IMPORTING e_object e_interactive,

handle_user_command

FOR EVENT user_command OF cl_gui_alv_grid

IMPORTING e_ucomm.

ENDCLASS. "lcl_event_handler DEFINITION

CLASS lcl_event_handler IMPLEMENTATION.

METHOD handle_toolbar.

DATA:

l_toolbar TYPE stb_button.

Here I replace SAP standard functions with own functions

READ TABLE e_object->mt_toolbar INTO l_toolbar

WITH KEY function = '&LOCAL&APPEND'.

IF sy-subrc = 0.

l_toolbar-function = 'OWN_APPEND'.

MODIFY e_object->mt_toolbar FROM l_toolbar INDEX sy-tabix.

ENDIF.

READ TABLE e_object->mt_toolbar INTO l_toolbar

WITH KEY function = '&LOCAL&COPY_ROW'.

IF sy-subrc = 0.

l_toolbar-function = 'OWN_COPY_ROW'.

MODIFY e_object->mt_toolbar FROM l_toolbar INDEX sy-tabix.

ENDIF.

ENDMETHOD. "handle_toolbar

METHOD handle_user_command.

CASE e_ucomm.

WHEN 'OWN_APPEND'.

CALL METHOD ref_alv->check_changed_data

IMPORTING
e_valid =
CHANGING
c_refresh = 'X'

CREATE YOUR OWN CODE HERE

CALL METHOD ref_alv->refresh_table_display

EXPORTING

is_stable = 'X'

i_soft_refresh =
EXCEPTIONS
finished = 1
others = 2

ENDMETHOD. "handle_user_command

ENDCLASS. "lcl_event_handler IMPLEMENTATION

Kind regards
