Data Presentation: DevExpress Silverlight TreeList
Data Presentation

The DevExpress Silverlight TreeList control can be used in both bound or unbound mode. In bound mode, the TreeList can present any self-referenced data structure. Unbound mode allows you to manually create and populate the tree (as your business needs dictate). Unbound mode supports on demand loading of individual nodes resulting in ultra-fast information display.
