Hello
Check the below code:
CLASS eventhandler DEFINITION.
  PUBLIC SECTION.
    METHODS:
      handle_double_click FOR EVENT double_click
        OF cl_gui_alv_grid
        IMPORTING e_row
                  e_column
      ENDCLASS.                    "EVENTHANDLER DEFINITION
CLASS eventhandler IMPLEMENTATION.
   METHOD handle_double_click.
    PERFORM handle_double_click USING e_row.
  ENDMETHOD.                    "HANDLE_DOUBLE_CLICK
ENDCLASS.                    "EVENTHANDLER IMPLEMENTATION
declare object of type eventhandler
DATA:  eventhandler_object  TYPE REF TO eventhandler.
  READ TABLE <g_t_alv> INTO g_r_itab INDEX e_row-index .
  IF sy-subrc EQ 0.
          CALL SCREEN 9001.
    ENDIF.
  ENDIF.
Within Screen 9001 u can write u r code to display the data in ALV grid container and use REFRESH_TABLE_FOR_DISPLAY  method also to have the updated data int he grid on double click.
