How can I register an EVENT for ALV-GRID?????

[Former Member]

Hi,

i have create Events for my ALV-Grid Table (cl_gui_alv_grid).

But there is one Problem!!!!

Which Event must i create, if users write something in the ALV row and press to key "enter" ???

With kind regards

Ersin

- the ALV must be editable

- you must set handler for either event data_changed or data_changed_finished

- then activate the events trigger when you press ENTER with the following

  CALL METHOD g_alv_grid_ref->register_edit_event
    EXPORTING
      i_event_id = cl_gui_alv_grid=>mc_evt_enter. "trigger your handler after ENTER is pressed

Hi,

If You want an event to get triggered every time an entry is made/changed in an editable cell, you can use 'DATA_CHANGED' OF CL_GUI_ALV_GRID. This will also trigger whenever one presses enter, after changing an entry.

Else, if You only want this whenever enter if pressed use the following code

'CALL METHOD g_alv_grid_ref->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_enter.'

Thanks for your helps,

i call the "register_edit_event" after "et_table_for_first_display" .

But it doesnt work`??

If i press enter on a row and debug, there is no calling event!!!

CALL METHOD gr_grid_d0100->set_table_for_first_display

EXPORTING

i_consistency_check = l_consistency_check

is_variant = ls_vari

i_save = 'A'

i_default = con_true

is_layout = ls_layo

is_print = ls_prnt

it_hyperlink = lt_hype

CHANGING

it_outtab = gt_outtab[]

it_fieldcatalog = lt_fcat.

CALL METHOD gr_grid_d0100->register_edit_event

EXPORTING

i_event_id = cl_gui_alv_grid=>mc_evt_enter.

Did you set the handler for one of forementioned events? If no, please suplement your code with the following

"create handler class 
CLASS lcl_gui_alv_event_receiver DEFINITION.
  PUBLIC SECTION.
    METHODS:
"        Controlling data changes when ALV Grid is editable
          handle_data_changed FOR EVENT data_changed OF cl_gui_alv_grid
                              IMPORTING er_data_changed e_onf4 e_onf4_before e_onf4_after,
"       To be triggered after data changing is finished
          handle_data_changed_finished FOR EVENT data_changed_finished OF cl_gui_alv_grid
                                       IMPORTING e_modified ,
ENDCLASS.                   

"implement you handler methods

  ENDMETHOD .
ENDCLASS.

data:  g_alv_event_ref TYPE REF TO lcl_gui_alv_event_receiver.

CREATE OBJECT g_alv_event_ref.

"set handlers for these events
SET HANDLER:
  g_alv_event_ref->handle_data_changed FOR g_alv_grid_ref,

"register the events after pressing enter
CALL METHOD g_alv_grid_ref->register_edit_event
      EXPORTING
        i_event_id = cl_gui_alv_grid=>mc_evt_enter.
