I want to populate a field when another field was edited. So this is the method in the implementation.
When I press Enter nothing happens, but when i double click the change applies.
Do you have any idea or fix? I am using the class cl_gui_alv_grid.
METHOD data_changed_finished.
DATA: ls_inr TYPE LINE OF lvc_t_modi,
lv_stbl TYPE lvc_s_stbl,
gt_out type standard table of SPFLI,
ls_out LIKE LINE OF gt_out.
LOOP AT et_good_cells INTO ls_inr
WHERE fieldname = 'CITYFROM'.
EXIT.
ENDLOOP.
DATA:
ld_REFRESH_MODE TYPE SALV_DE_CONSTANT ,
ld_S_STABLE TYPE LVC_S_STBL.
ld_S_STABLE-row = 'X'.
ld_S_STABLE-col = 'X'.
IF sy-subrc = 0.
LOOP AT et_good_cells INTO ls_inr.
LOOP AT IT_SPFLI INTO ls_out
FROM ls_inr-row_id
TO ls_inr-row_id.
ls_out-DISTANCE = '556'.
MODIFY IT_SPFLI FROM ls_out.
ENDLOOP.
ENDLOOP.
ENDIF.
lv_stbl-row = 'X'.
lv_stbl-col = 'X'.
ld_S_STABLE-row = 'X'.
ld_S_STABLE-col = 'X'.
ld_REFRESH_MODE = 2.
CALL METHOD salv->REFRESH(
EXPORTING
REFRESH_MODE = ld_REFRESH_MODE
S_STABLE = ld_S_STABLE ).
ENDMETHOD.
So, as I said in the comments, it's obvious to me that the question is more about CL_GUI_ALV_GRID (not CL_SALV_TABLE). By default, the Enter key does not trigger the events DATA_CHANGED and DATA_CHANGED_FINISHED.
If you want this feature, you must call the method REGISTER_EDIT_EVENT and pass one of these two constants for the firing of the two events; you may call the method twice, once for the first constant and once for the second to combine their behaviors (EDIT Aug 10th/11th, 2024):
MC_EVT_ENTER:
DATA_CHANGED is fired if Enter is pressed and at least one cell is changed. DATA_CHANGED_FINISHED is fired if Enter is pressed, even if no cell was changed.MC_EVT_MODIFIED:
DATA_CHANGED first, DATA_CHANGED_FINISHED second) if one cell is changed and either Enter is pressed or the focus is changed to somewhere else in the ALV Grid (press an ALV toolbar button, go to another cell, column or row selection, etc.)Demo program (NB: if the table SBOOK is empty, fill it by calling the program SAPBC_DATA_GENERATOR):
REPORT z_demo.
