RadTreeList
for asp.net ajax
The Telerik AJAX TreeList control is the perfect fit for scenarios in which you
will need to combine treeview and grid in one control. Its hybrid structure empowers
you with the ability to visualize self-referencing data in a hierarchical view defining
primary/foreign key relations and using identical objects for source. The treelist
benefits both from a treeview's expand/collapse and items aligning capabilities
as well as from typical grid's features like sorting, paging, row selection, etc.
