I am creating TreeViewItem template (every treeview in app should have this style). When item is selected, all parents of this will be selected too. Fist level has different style of selection.
Can I do it only in xaml template?

When some item is selected I want select all it's parents. I tried demonstrate situation in the picture. First level in treeview has different style than another levels.
