Visible / invisible of custom container in screen

Question

hi all,
i have one custom container on my SUB SCREEN (named "CONT")
In MAIN SCREEN i have one push button and the above SUBSCREEN is there.
On pushing button, i want to hide or show the SUBSCREEN,
if SUBSCREEN contains IO Fields or Table control etc. then we can easily do that, but how to do the same in case of custom container??
please guide me...
Thanks in advance

Hi Jignesh,
We have got a method FREE in CL_GUI_CUSTOM_CONTAINER with that we can clear the content of the container
CALL SCREEN 200.
SET PF-STATUS 'ZSUB1'.
  IF L_FLAG NE 'X'.
    CREATE OBJECT MY_CONTAINER
      EXPORTING
        CONTAINER_NAME              = 'CCSUB'
       EXCEPTIONS
        CNTL_ERROR                  = 1
        CNTL_SYSTEM_ERROR           = 2
        CREATE_ERROR                = 3
        LIFETIME_ERROR              = 4
        LIFETIME_DYNPRO_DYNPRO_LINK = 5
        OTHERS                      = 6.
SELECT * FROM EKKO INTO TABLE GT_EKKO
             UP TO 10 ROWS.
    CREATE OBJECT ALV
      EXPORTING
        I_PARENT          = MY_CONTAINER
       EXCEPTIONS
        ERROR_CNTL_CREATE = 1
        ERROR_CNTL_INIT   = 2
        ERROR_CNTL_LINK   = 3
        ERROR_DP_CREATE   = 4
        OTHERS            = 5.
CALL METHOD ALV->SET_TABLE_FOR_FIRST_DISPLAY
      EXPORTING
        I_STRUCTURE_NAME              = 'EKKO'
      CHANGING
        IT_OUTTAB                     = GT_EKKO
      EXCEPTIONS
        INVALID_PARAMETER_COMBINATION = 1
        PROGRAM_ERROR                 = 2
        TOO_MANY_LINES                = 3
        OTHERS                        = 4.
  ENDIF.
MODULE USER_COMMAND_0200 INPUT.
  CASE SY-UCOMM.
    WHEN 'PUSH'.
      IF L_FLAG = 'X'.
        CLEAR L_FLAG.
      ELSE.
        CALL METHOD MY_CONTAINER->FREE.
        L_FLAG = 'X'.
      ENDIF.
    WHEN 'BACK'.
      LEAVE PROGRAM.
  ENDCASE.
ENDMODULE.
