Hi Harsha Hegde,
You can use the GetXml-LoadXml methods of the RadTreeView.
Here is nice article about loading the tree from Xml: http://www.telerik.com/help/aspnet-ajax/tree_databindingxmlload.html
Here is the demo page about this functionality: http://demos.telerik.com/aspnet-ajax/treeview/examples/programming/xmlfile/defaultcs.aspx
Hope this solves your problem!
