processing input fields on OO ALV display

Former Member — Mon, 06 Nov 2006 17:17:41 GMT

Hello,

I have implemented OO ALV display and set a field as input field. How can I process all the entries after the user enters values at multiple lines and presses ENTER?

Thx in advance.

U should use the event DATA_CHANGED to elaborate or check the new hits and active the event linked to attribute EVT_ENTER.

Hi Ali,

You should use the following method in order to get the selected rows.

data: ref_alv_grid TYPE REF TO cl_gui_alv_grid.

CALL METHOD ref_alv_grid->get_selected_rows

IMPORTING

et_row_no = lt_selected_rows.

you can also set a hanlder to the data_change event.

CLASS lcl_manejador_eventos DEFINITION.

PUBLIC SECTION.

METHODS:

handle_data_changed

FOR EVENT data_changed OF cl_gui_alv_grid

IMPORTING er_data_changed.

ENDCLASS. "lcl_manejador_eventos DEFINITION

CLASS lcl_manejador_eventos IMPLEMENTATION.

METHOD handle_data_changed.

PERFORM handle_data_changed USING er_data_changed.

ENDMETHOD. "handle_data_changed

ENDCLASS. "lcl_manejador_eventos IMPLEMENTATION

FORM handle_data_changed USING p_er_data_changed

TYPE REF TO cl_alv_changed_data_protocol.

DATA: ls_mod_cell TYPE lvc_s_modi,

lv_value TYPE lvc_value.

LOOP AT p_er_data_changed->mt_mod_cells INTO ls_mod_cell.

.....

ENDLOOP.

in order to set the handler you should do this before the set_table_for_first_display.

DATA ref_manejador_eventos TYPE REF TO lcl_manejador_eventos.

CREATE OBJECT ref_manejador_eventos.

SET HANDLER ref_manejador_eventos->handle_data_changed FOR ref_alv_grid.

I don't know if you already know how to get the ENTER. So I written it over.

Detects the ENTER

CALL METHOD ref_alv_grid->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_enter.

Detects when you move to another cell after a data changed

CALL METHOD ref_alv_grid->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_modified.

Regards,

Eric

See the program demo BCALV_EDIT_03.

To active the event for the ENTER key:

CALL METHOD <GRID>->REGISTER_EDIT_EVENT EXPORTING

I_EVENT_ID = CL_GUI_ALV_GRID=>MC_EVT_ENTER.
