Hi,

You need to call it in set handler .

    call method grid1->set_table_for_first_display
      exporting
        is_layout                     = gs_layout
        it_toolbar_excluding          = gs_exclude
      changing
        it_outtab                     = i_yctc4[]
        it_fieldcatalog               = i_fieldcat[]
        it_sort                       = ls_sort
      exceptions
        invalid_parameter_combination = 1
        program_error                 = 2
        too_many_lines                = 3
        others                        = 4.
    if sy-subrc ne 0.
      message id sy-msgid type sy-msgty number sy-msgno
                  with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    endif.
    endif.

    if event_receiver_grid is initial.
      create object event_receiver_grid.
    endif.
    set handler event_receiver_grid->handle_toolbar_0100 for grid1.
    call method grid1->set_toolbar_interactive.

it_toolbar_excluding = gs_exclude

gs_exclude contains all buttons you wish to exclude from ALV. You will need to do a bit of research to find the name of the button and append it to gs_exclude.

Hope thi shelps.

call method grid1->set_table_for_first_display

exporting

is_layout = gs_layout

it_toolbar_excluding = gs_exclude

Hi,

when i press the button on the out put screen the control comes to

case e_ucomm.

when 'ADD'.

call method g_grid->get_selected_rows

importing et_index_rows = lt_rows.

call method cl_gui_cfw=>flush.

if sy-subrc ne 0.

else.

perform test..

call method g_grid->refresh_table_display. --- from here it again goes tothie code below

method handle_toolbar.

• 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 'ADD' to ls_toolbar-function.

move icon_employee to ls_toolbar-icon.

move 'Show Bookings'(111) to ls_toolbar-quickinfo.

move 'Add Material'(112) to ls_toolbar-text.

move ' ' to ls_toolbar-disabled.

append ls_toolbar to e_object->mt_toolbar.

if flag = 'X'. -

---

This time flag is X and button gets disabled

loop at e_object->mt_toolbar into ls_toolbar.

if ls_toolbar-function = 'ADD'.

ls_toolbar-disabled = 'X'.

modify e_object->mt_toolbar from ls_toolbar.

endif.

endloop.

endif.

let me know

Thanks
