Single Click on a Row in ALV Grid

Question

Hello,
I am using 'CL_GUI_ALV_GRID' class for displaying an ALV grid.
The requirement is when an user clicks on a row of the grid, a popup should be displayed with the details of that line, the user can edit/enter some fields there and when clicks on the save button, the updated values should get saved in database.
Which event needs to be used for this? A sample code will be very useful.
Thanks
Indrajit.

Hello Indrajit
The same behaviour you see in the IDoc Monitor (transaction WE02, report RSEIDOC2). The event you need to handle is DELAYED_CHANGED_SEL_CALLBACK.
Coding copied from RSEIDOC_ALV_CL:
***INCLUDE CLASS_ALV .
* LOCAL CLASSES: Definition für ALV Ereignisse
CLASS lcl_event_receiver DEFINITION.
  PUBLIC SECTION.
    METHODS:
    handle_delayed_changed_sel_cb
        FOR EVENT delayed_changed_sel_callback OF cl_gui_alv_grid,
METHOD handle_delayed_changed_sel_cb.
data: lt_rows TYPE lvc_t_row.
data: l_row   TYPE lvc_s_row.
  CALL METHOD grid->get_selected_rows
           IMPORTING et_index_rows = lt_rows.
  CALL METHOD cl_gui_cfw=>flush.
  read table lt_rows index 1 transporting no fields.
  if sy-subrc ne 0.
    exit.
  endif.
  perform fill_special_values tables lt_rows.
  need_refresh = 'N'.
  set screen 100.
  leave screen.
ENDMETHOD.
