Hi Satheesh,

Did you create the container ?

*--- ALV Grid instance reference

DATA gr_alvgrid TYPE REF TO cl_gui_alv_grid .

*--- Name of the custom control added on the screen

DATA gc_custom_control_name TYPE scrfname VALUE ‘CC_ALV’ .

*--- Custom container instance reference

DATA gr_ccontainer TYPE REF TO cl_gui_custom_container .

IF gr_alvgrid IS INITIAL .

*----Creating custom container instance

CREATE OBJECT gr_ccontainer

EXPORTING

container_name = gc_custom_control_name

EXCEPTIONS

cntl_error = 1

cntl_system_error = 2

create_error = 3

lifetime_error = 4

lifetime_dynpro_dynpro_link = 5

others = 6 .

IF sy-subrc <> 0.

*--Exception handling

ENDIF.

Now pass this while creating the grid object

*----Creating ALV Grid instance

CREATE OBJECT gr_alvgrid

EXPORTING

i_parent = gr_ccontainer

EXCEPTIONS

error_cntl_create = 1

error_cntl_init = 2

error_cntl_link = 3

error_dp_create = 4

others = 5 .

IF sy-subrc <> 0.

*--Exception

Regards,

Vidya

It shud be like this

DATA TABLE_OBJ TYPE REF TO CL_GUI_ALV_GRID.

create the TABLE control

CREATE OBJECT TABLE_OBJ

EXPORTING I_PARENT = CONTAINER.

it will definately solve it ...

Reward please if helpful

Regards

Hi Satheesh,

We use the event “toolbar” to add the button and the event “user_command” to implement the new function.

so in our class we need to define two methods to handle these two events first..

u can find this out from standard program 'BCALV_GRID_05'

briefly, define 2 methods ..say

in class declaration.

METHODS:

HANDLE_TOOLBAR

FOR EVENT TOOLBAR OF CL_GUI_ALV_GRID

IMPORTING E_OBJECT E_INTERACTIVE,

HANDLE_USER_COMMAND

FOR EVENT USER_COMMAND OF CL_GUI_ALV_GRID

IMPORTING E_UCOMM.

now in the class implemenatation.

METHOD HANDLE_TOOLBAR.

DATA: LS_TOOLBAR TYPE STB_BUTTON.

append a separator to normal toolbar

CLEAR LS_TOOLBAR.

MOVE 3 TO LS_TOOLBAR-BUTN_TYPE.

APPEND LS_TOOLBAR TO E_OBJECT->MT_TOOLBAR.

append an icon to show booking table

CLEAR LS_TOOLBAR.

MOVE 'BOOKINGS' TO LS_TOOLBAR-FUNCTION.

MOVE ICON_EMPLOYEE TO LS_TOOLBAR-ICON.

MOVE 'Show Bookings'(111) TO LS_TOOLBAR-QUICKINFO.

MOVE 'Detail'(112) TO LS_TOOLBAR-TEXT.

MOVE ' ' TO LS_TOOLBAR-DISABLED.

APPEND LS_TOOLBAR TO E_OBJECT->MT_TOOLBAR.

ENDMETHOD.

METHOD HANDLE_USER_COMMAND.

§ 3.In event handler method for event USER_COMMAND: Query your
function codes defined in step 2 and react accordingly.

DATA: LT_ROWS TYPE LVC_T_ROW.

CASE E_UCOMM.

WHEN 'BOOKINGS'.

CALL METHOD GRID1->GET_SELECTED_ROWS

IMPORTING ET_INDEX_ROWS = LT_ROWS.

CALL METHOD CL_GUI_CFW=>FLUSH.

IF SY-SUBRC NE 0.

add your handling, for example

CALL FUNCTION 'POPUP_TO_INFORM'

EXPORTING

TITEL = G_REPID

TXT2 = SY-SUBRC

TXT1 = 'Error in Flush'(500).

endif.

ENDCASE.

ENDMETHOD. "handle_user_command

after creating the grid object...

GS_LAYOUT-SEL_MODE = 'A'.

CALL METHOD GRID1->SET_TABLE_FOR_FIRST_DISPLAY

EXPORTING I_STRUCTURE_NAME = 'SFLIGHT'

IS_LAYOUT = GS_LAYOUT

CHANGING IT_OUTTAB = GT_SFLIGHT.

CREATE OBJECT EVENT_RECEIVER.

SET HANDLER EVENT_RECEIVER->HANDLE_USER_COMMAND FOR GRID1.

SET HANDLER EVENT_RECEIVER->HANDLE_TOOLBAR FOR GRID1.

§ 4.Call method 'set_toolbar_interactive' to raise event TOOLBAR.

CALL METHOD GRID1->SET_TOOLBAR_INTERACTIVE.

SET HANDLER EVENT_RECEIVER->HANDLE_USER_COMMAND FOR GRID1.

SET HANDLER EVENT_RECEIVER->HANDLE_TOOLBAR FOR GRID1.

Regadrds,

Vidya.
