Get functions method

Hello Experts

Happy new year to everyone.

Thanks for all the help till now.

I am again stuck with one of the issue. The scenario goes like this-

i am displaying full screen ALv grid output using class cl_salv_table.

I havw created a custom GUI status which has 3 buttons. I want to hide one of them based on certain condition.

following is the code which i have written-

data : lr_functions TYPE REF TO cl_salv_functions,
            lt_func_list TYPE salv_t_ui_func.

lr_functions = o_alv->get_functions( )

lt_func_list = lr_functions->get_functions( ).

the list which i get lt_func_list does not populate with all the application toolbar functions which i added.

Please help.

Thanks.
