Container name validation

Former Member — Tue, 28 Nov 2006 10:06:39 GMT

Is it possible to validate the CONTAINER_NAME when we create a custom container on a screen.Is there any table where this name is stored.

Hi Ravi,

What do you mean by container name... is it the one which we supply in the screen painter for a control area?

HI,

We create the Container in the Screen and we give the name to that container

Declare it as

go_custom_container TYPE REF TO cl_gui_custom_container

Then you can write the code like ...

     IF go_custom_container IS INITIAL.
       CREATE OBJECT go_custom_container
         EXPORTING container_name = 'ALV_CONTAINER'.
       CREATE OBJECT go_grid
         EXPORTING
           i_parent = go_custom_container.

Hi Ravi,

You can get the screen fields for a screen using FM RS_SCREEN_IMPORT.

then you can validate the container name from the export parameter F_G.

hope this helps.

Hello Ravi,

This container name should not be validated. In general, the name of the screen element does not change. Therefore, it is usually hardcoded as shown in the example above.

And I believe this is the recommended practice. If you try to validate such screen elements, it will unnecessarily increase the runtime of your application.

However, for reasons of technical interest, Kinshuk's solution above will do the trick for you.
