Alternating the Appearance of Items

  • Article

This example demonstrates how to alternate the appearance of items in a ListBox and a Treeview by using the AlternationConverter and the ItemsControl.AlternationIndex attached property. The ListBox groups its items, and both the GroupItem headings and the items in the ListBox have alternating appearances. You can alternate the appearance of the GroupItem heading and items in the ListBox independently of each other.

The items in the TreeView have a different appearance in each level of the TreeView. In the first level, all items are bold. In the second level, the items alternate between italicized text and normal text. In the third level, the backgrounds of the items alternate among three colors.
