ALV grid refresh after user_command

[Former Member]

Hi all,

i have a problem with my code, i use 2 alv grids in my code and sometimes i need to refresh the alv grids, the problem is that the method grid->REFRESH_TABLE_DISPLAY works only as long as the PAI of screen 100 is not triggerd, it means, when i click on something that has a function code and will cause the PAI of screen 100 to be triggered, i can no more change the alv grids, does any one know where the problem is? thanks in advance.
here is my code:

CALL SCREEN 100.

MODULE status_0100 OUTPUT.

SET PF-STATUS 'STATUS'.

SET TITLEBAR 'TITLE'.

IF init is initial.

RECEIVING

CALL METHOD splitter->get_container

EXPORTING

row = 2

column = 1

RECEIVING

container = container_2.

CALL METHOD splitter->get_container

EXPORTING

row = 3

column = 1

RECEIVING

container = container_3.

CALL METHOD splitter->set_row_height

EXPORTING

id = 1

height = 57.

CALL METHOD splitter->set_row_height

EXPORTING

id = 3

height = 39.

CREATE OBJECT grid1

EXPORTING

i_parent = container_1.

CREATE OBJECT grid2

EXPORTING

Hi Masood,

use the below satement to free the alv objects...

if grid1 is not initial.

     CALL METHOD grid1->free

else.

    free grid1.

endif.

if grid2 is not initial.

     CALL METHOD grid2->free

else.

    free grid1.

endif.

if container_1 is not initial.

     CALL METHOD container_1->free

else.

    free container_1.

endif.

if container_2 is not initial.

     CALL METHOD container_2->free

else.

    free container_2.

endif.

if splitter is not initial.

     CALL METHOD splitter->free

else.

    free splitter.

endif.

i used the statement above at the end of PAI of screen 100. but now when i click on something that has a function code and will cause the PAI of screen 100 to be triggered, the objects on the screen 100 will be removed, what should i do?

[former_member224797]

Free all the objects just before the (IF init is initial.) check is performed.

[Former Member]

It makes no difference, they will be removed, it's like that when i free one object i can't assign anything to it again.

[Former Member]

Can you put some screen shots showing the issue?

[former_member224797]

bro..

If you still facing da proble then i guss the problem is with this "IF init is initial" statement.

bcz if "init" containing some value even after the refresh it wont go inside da condition nd display da ALV.

So after free all  objects ,make sure that the program flow go to the alv display.......).

[Former Member]

it didn't solve my problem, here is what i get when i run the program,

and when i click on any button or radio button that will cause the PAI of the screen 100 to be triggered i get the following,

and yes, i modified my code so that there is no more "if init is initial" in the PBO of the screen 100, and i inserted at the beginning of the PBO 100 the following statement:

    if grid1 is not initial.
      CALL METHOD grid1->free.
    else.
      free grid1.
    endif.

    if grid2 is not initial.
      CALL METHOD grid2->free.
    else.
      free grid1.
    endif.

    if container_1 is not initial.
      CALL METHOD container_1->free.
    else.
      free container_1.
    endif.

    if container_2 is not initial.
      CALL METHOD container_2->free.
    else.
      free container_2.
    endif.

    if splitter is not initial.
      CALL METHOD splitter->free.
    else.
      free splitter.
    endif.

and after that i create objects and display grids.

Hi,

I also had a problem with REFRESH_TABLE_DISPLAY. Instead of this I used SET_FOR_FIRST_DISLPAY again and it worked.

Cheers,
