I am learning OO ALV. Now, I am settin NO_TOOLBAR in my layout. And my ALV doesn't display my ALV toolbar (I am using OO ALV set_table_for_first_display) Now I am adding copy of a standard toolbar into my gui status. Now I want use this toolbar (sum, avg,filter and other) buttons. But when I press a button it isn't handling. How can I execute this standard button events for my ALV grid?
