Hi,

Modify the internal table and then use refresh_table_display.

Hello Swami

I think you are mixing up different aspects of ALV list programming.

If your ALV list is editable (including adding and deleting rows) then you have to call method <b>go_grid->check_changed_data</b> in PAI of the dynpro hosting the ALV grid control in rorder to transfer the changes at the <i>frontend</i> (i.e. the control) to the <i>backend</i> (i.e. the output itab in your ABAP program).

If you want to modify the ALV toolbar dynamically please refer to my sample report in thread

<a href="https://forums.sdn.sap.com/click.jspa?searchID=713140&messageID=2884705">Thread: how to disable self defined button from ALV Toolbar when ok_code ='BACK'</a>

Hi,

1. you require to define handle_data_changed method of lcl_event_receiver

class lcl_event_receiver definition.

handle_data_changed

for event data_changed of cl_gui_alv_grid

importing er_data_changed.

endclass. "lcl_event_receiver DEFINITION

2. After displaying ALV first time. call the above method.

start-of-selection.

call method g_alv_grid->set_table_for_first_display

EXPORTING

is_variant = variant

is_layout = layout

is_print = print

CHANGING

it_outtab = OUTPUT[] "internal anle

it_fieldcatalog = g_t_flcat[]. " field catalog

if sy-subrc <> 0.

write: 'Method call ''Set_table_for_first_display'' failed.'.

exit.

endif.

set handler g_alv_event->handle_data_changed

for g_alv_grid.

3. in the implementation of method

call refresh grid.

data: g_stable type LVC_S_STBL.

method handle_data_changed.

• //code to modify internal table

• Refresh the Grid without changing the current view

g_stable-row = '1'.

call method g_alv_grid->refresh_table_display

exporting IS_STABLE = g_stable.

endmethod.
