Hi David Cardona,
Yes, currently the TreeListView is a CTP and it is lacking its expected documentation. Please note that significant changes are expected in the controls since we are going to base it on the GridView. It is best not to use in a production environment.
Indeed the text of this article refers to a class named NorthwindDataSource while the class in code is called HierarchicalDataSource. It appears that they are the same thing, a code updated has not been reflected in the text.
Thanks for bringing our attention to this, we will update this article.
Binding the TreeView is very much like binding any other items control. In this article LoadOnDemand is used which defers loading of children before they are expanded.
