Hello suman,
We are adding RadTreeListView for ASP.NET Ajax in Q3 2010. Please see what is coming in ASP.NET track in
this blog post.
The RadTreeListView for Silverlight/WPF is available as an inheritor of GridViewDataControl since Q2 2010. It allows editing. Please check our online demos
here.
Sincerely yours,
Veselin Vasilev
