Is it possible to emulate border-collapse (ala CSS) in a WPF ItemsControl?

Question

I\'m styling the items in a WPF ListBox, and want to put a border around each item. With BorderThickness set to 1, for example, the top-bottom borders

Answer 1

One thing that comes to mind is to make use of AlternationIndex. This will require you to set something like AlternationCount="10000" on the ListBox. After that you can set BorderThickess="1,0,1,1" and use a DataTrigger to find the first ListBoxItem
