Hi,

GO to SE41 copy the status STANDARD from the program SAPLKKBL..And give the status name and your program name.

In the parameter I_CALLBACK_PF_STATUS_SET give the form name 'PF_STATUS_SET'.

In the subroutine.

FORM PF_STATUS_SET.

SET PF-STATUS 'STATUS NAME THAT YOU GAVE IN SE41'.

ENDFORM.

• For user command pass the parameter I_CALLBACK_USER_COMMAND with the user command subroutine name..

FORM USER_COMMAND USING R_UCOMM LIKE SY-UCOMM

RS_SELFIELD TYPE SLIS_SELFIELD.

...

IF R_UCOMM = ''.

...

ENDIF.

ENDFORM.

• Example

CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'

EXPORTING

i_callback_program = lv_repid

I_CALLBACK_PF_STATUS_SET = 'PF_STATUS_SET'

I_CALLBACK_USER_COMMAND = 'USER_COMMAND'

............

Thanks,

Hello,

To add a push button and handle it,you have to define a local class and use the methods <b>handle_toolbar</b> and <b>handle_user_command</b>.Here is a sample code:

----

---

• CLASS lcl_eh DEFINITION

----

---

*

----

---

CLASS lcl_eh DEFINITION.

PUBLIC SECTION.

DATA:

<b>ls_toolbar TYPE stb_button</b>.

METHODS:

<b>handle_toolbar</b>

FOR EVENT toolbar OF cl_gui_alv_grid

IMPORTING e_object e_interactive,

<b>handle_user_command</b>

FOR EVENT user_command OF cl_gui_alv_grid

IMPORTING e_ucomm.

ENDCLASS. "lcl_eh DEFINITION

***********************************************************************

*Type referencing an object of the class

***********************************************************************

<b>DATA: lo_obj TYPE REF TO lcl_eh.</b>

<b>APPEND ls_toolbar TO e_object->mt_toolbar.</b>

ENDMETHOD. "handle_toolbar

***********************************************************************

*METHOD: HANDLE_USER_COMMAND

*DESCRIPTION: This method is used to handle the push button

***********************************************************************

Hello Ajay

Assuming that you want to have a "push-button" column, i.e. push-buttons <b>within</b> an ALV grid then you need to implement the following steps:

(1) Set the style of the column as button

  ls_fcat-style = CL_GUI_ALV_GRID => MC_STYLE_BUTTON.

(2) When the user pushes the button event <b>BUTTON_CLICK</b> is triggered. Thus, define an appropriate event handler method.

CLASS event_handler_class DEFINITION.

• Adding Buttons to Toolbar

DATA: ls_toolbar TYPE stb_button.

• Adding 'Select All' Button on the toolbar

CLEAR ls_toolbar.

MOVE 'SELECT_ALL' TO ls_toolbar-function.

MOVE 0 TO ls_toolbar-butn_type.

MOVE 'Select All' TO ls_toolbar-text.

MOVE icon_create TO ls_toolbar-icon.

MOVE 'Select All' TO ls_toolbar-quickinfo. " Select All

APPEND ls_toolbar TO p_object->mt_toolbar . "INDEX 1.

ENDFORM.

In the form Hndle User Command you write you own code.

FORM handle_user_command_prod USING p_ucomm TYPE sy-ucomm.

*

IF p_ucomm = 'SELECT_ALL'.

LOOP AT gt_product INTO gs_product.

gs_product-product_check = 'X'.

MODIFY gt_product FROM gs_product TRANSPORTING product_check.

CLEAR: gs_product.

ENDLOOP.

ENDIF.

ENDORM.

you write this code before Set table for first display.

SET HANDLER gp_handler->handle_user_command_prod FOR gp_alv_grid_prod.

SET HANDLER gp_handler->handle_alv_toolbar_prod FOR gp_alv_grid_prod.
