Hi Suman Rao,
Unfortunately I cannot picture the hierarchy you need to display from the table snapshot you sent. I cannot find a column that has unique values in every row. Is the primary key for this table formed by more than one column? What data does the ParentID column refers to? And how that data reflects the ChildLevel column?
Also, have you checked the sample project illustrating how to display a FlatHierarchy in the RadTreeView using RIA Services? Does that help?
Can you please elaborate more on the structure of your data and we would be glad to assist you further.
