Problem with Custom container ->cl_gui_custom_container/cl_gui_alv_grid

[ramakrishna_koliparthi]

Hi,

I want to reuse the same custom container screen for a different data.

First screen there will be button 1 and button 2

if I click button 1 then calculate and display data in custom container, if button 2 is clicked then calculate and display data with in the same custom container.

For this

1. Created Custom container - CONTAINER

2. In program defined and created custom container and custom alv grid

g_custom_container TYPE REF TO cl_gui_custom_container,
        alv_grid                     TYPE REF TO cl_gui_alv_grid.
       IF g_custom_container IS INITIAL.
            CREATE OBJECT g_custom_container
                EXPORTING
              container_name = 'CONTAINER'.

            CREATE OBJECT alv_grid
               EXPORTING
                i_parent = g_custom_container.
      ENDIF.

3. Display data using CALL METHOD alv_grid->set_table_for_first_display

every thing works great for button 1

4. when button 2 is clicked then calculate and display different set of data in same custom container which is used earlier.

5. here I used

call method alv_grid->free.
    call method g_custom_container->free.

6. create above objects once again and tried to use

call method alv_grid->set_table_for_first_display

, to reuse the same custom container 'CONTAINER' again for a different set of data and getting ABAP dump.

In debug mode, when I used the above method FREE for both ALV_GRID and G_CUSTOM_CONTAINER objects are not clearing.

Please let me know how can I reuse the same container for a different set of data when button2 is pressed.

Thanks in advance,

Krishna

Hi,

try this way:

call method alv_grid->finalize.
call method alv_grid->free.
call method g_custom_container->finalize.
call method g_custom_container->free.

Hello Krishna

I would recommend to use a different approach instead of trying to initialize your container instances:

DATA:
  go_container_1 TYPE REF TO cl_gui_custom_container,
  go_container_2 TYPE REF TO cl_gui_custom_container,
  go_grid_1          TYPE REF TO cl_gui_alv_grid,
  go_grid_2          TYPE REF TO cl_gui_alv_grid.

" NOTE: Do this coding BEFORE calling the screen

* (1) Create 2 containers
CREATE OBJECT g_container_1
                EXPORTING
              container_name = 'CONTAINER'.
CREATE OBJECT g_container_2
                EXPORTING
              container_name = 'CONTAINER'.
" NOTE: If it is not possible to use the same container name then either create an additional
"            dummy screen having a second CUSTOM_CONTROL element or replace
" the customer containers with docking containers -> here you do not need to give a container name

* (2) Create 2 grid instances using a different container

* (3) Link the first container to the screen using its LINK method:
  CALL METHOD go_container_1
    EXPORTING 
       repid = <...>
      dynnr = <...>.

* (4) Perhaps you need to define a second dummy screen to which you link the second container

* (5) Display first grid instance (as default)

Now when the user pushes button 2 (to display the second grid) link container_1 to the dummy screen

and link container_2 to your main screen.

Hi Ram,

Try using CLEAR statement, instead of FREE.

CLEAR: g_custom_container.

Thanks all for the suggestions.

I tried all options and it hasn't worked when I clicked back button, giving dump. Finally i created 2 screens and removed free statement and it worked well.

Thanks
