Hierarchical data sources migrated to CodePlex
I just migrated my ObjectHierarchicalDataSource and CompositeHierarchicalDataSource projects from GotDotNet to CodePlex.
These data sources enable Menu and TreeView to declaratively bind to almost arbitrary data.
UPDATE: those data sources work with other hierarchical data controls such as Telerik's own Menu and TreeView.
