title: Listbox Scrollbar customization in WPF
body: <p>I'm making an application for being used in a touch screen. One of the forms shows a listbox with scrollbar activated that is a little bit tricky to use by touching the screen with fingers.</p>
  
  <p>I have tried to make an style that makes bigger buttons inside the scrollbar but I can't apply it to a listbox.</p>
  
  <p>Is it possible to make a style for make bigger buttons in a scrollbar inside a listbox?</p>
  
  <p>Thanks</p>
