you can check it by adding code in .htm ,do_prepare_output( ) ,IF_BSP_WD_TOOLBAR_CALLBACK~GET_BUTTONS method of view as suggested above also.
but in normal cases we never face any business requirement where you have to display only your custom view, you always need to display yours views,assignment block in standard view set or in overview page.If you use your custom view standalone(i think which never need in real business scenario) there are some other things also which not works.
