The following example shows how to display multiple collections and items as one list using the CompositeCollection class. In this example, GreekGods is an ObservableCollection of GreekGod custom objects. DataTemplates are defined so that GreekGod objects and GreekHero objects appear with a gold and a cyan foreground color respectively.
