can get you started on how to use the RadTreeView

, you'll have to extend the self-referencing data implementation like demonstrated in the attached sample.
Another useful resource is this forum thread
that describes how to configure the entity model on the server to turn the flat colelction into a hierarchical collection and then display the hierarchy in the RadTreeView
I hope this information will help you, but please let us know if we can further assist you.
