title: Removing Blue Border around treeviewitem in Expression Blend
body: <p>I'm building a silverlight app in Blend that will contain a treeview and treeviewitems.  The contents of my treeviewitems all have a blue border (when clicked and when you hover the mouse over), as you can see in the image I linked to.  I cannot figure out what causes that border, or how to remove it; anyone know where to get at it?  I've tried looking in the various treeview related templates, but I've had no luck so far.</p>
