Handling Double click on a Pop-up screen with ALV Grid

Question

Hello Experts,
I have an issue handling double click on ALV Pop-up screen. I tried to achive this using following steps.
1. I defined a local class in Top-include to handle double click and implemented it in the following way.
CLASS lcl_alv_event_handler DEFINITION.
PUBLIC SECTION.
CLASS-METHODS:
on_double_click FOR EVENT double_click
OF cl_gui_alv_grid
IMPORTING e_row
e_column
es_row_no.
ENDCLASS. "lcl_alv_event_handler DEFINITION
*~~~ Implementation code
CLASS lcl_alv_event_handler IMPLEMENTATION.
To handle Selection of Issue data on Screen 100
METHOD on_double_click.
DATA: lt_row_no TYPE lvc_t_roid,
ls_req TYPE zcst_zirt_seltab.
READ TABLE gt_req
INTO ls_req
INDEX e_row-index.
g_req_id = ls_req-zzrequest_id.
gv_selected = true.
CALL METHOD go_alv->dispatch
EXPORTING
cargo = 'OK'
eventid = 3
is_shellevent = ' '
is_systemdispatch = 'X'
EXCEPTIONS
cntl_error = 1
OTHERS = 2.
IF sy-subrc 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
ENDMETHOD. "on_double_click
ENDCLASS. "lcl_alv_event_handler IMPLEMENTATION
2. Registered the event in the PBO module of the screen
ls_events-eventid = 3.
ls_events-appl_event = gc_true.
APPEND ls_events TO lt_events.
CALL METHOD co_alv->set_registered_events
EXPORTING
events = lt_events
EXCEPTIONS
cntl_error = 1
cntl_system_error = 2
illegal_event_combination = 3
OTHERS = 4.
IF sy-subrc 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
CREATE OBJECT co_alv_event_handler.
SET HANDLER: co_alv_event_handler->on_double_click FOR co_alv.
CALL METHOD co_alv->set_toolbar_interactive.
3. In the PAI module of Screen, tried to handle the event 'OK' that waqs registred in PBO.
CASE save_ok.
WHEN 'OK'.
Get selected line
CALL METHOD io_alv->get_selected_rows
IMPORTING
et_index_rows = lt_rows
et_row_no = lt_rows_no.
IF NOT lt_rows IS INITIAL.
READ TABLE lt_rows INTO ls_rows INDEX 1.
IF sy-subrc EQ 0.
gv_selected = 'X'.
READ TABLE it_req
INTO ls_req
INDEX ls_rows-index.
e_req_id = ls_req-zzrequest_id.
SET SCREEN 0.
ENDIF.
ELSE.
SET SCREEN 0.
ENDIF.
With this code what is happening is, when user double clicks a line on Pop-up screen with ALV grid data, the program is able to successfully get into the class implementation but the control is not going to PAI module to execute the OK_code handling part.
Am I doing this in the right way? Appreciate quick suggestions. Proper posts will be thoroughly awarded with points.
Thx.

Answer 1

Put your code into the Event handler Implementation of Double Click which is there in the PAI Module.
