WPF ListBox's scrollviewer customizable so that there is no Scrollbar, only RepeatButtons

I would like to customize the scrollbars of a listbox's scrollviewer in such a way that the scrollbar only consists of a RepeatButton for scrolling up and a Repeatbut开发者_JAVA百科ton for scrolling down. Nothing else. There should be no scrollbar (track) between the buttons. One button should be to the left of the ItemsPanel (scroll up) and the other on the right of the ItemsPanel.

Is that possible?

I made a Vertical scrollbar with only repeat buttons and pls have look.
