Hi Tina,

The link are useful, but I am not sure how to build my HierarchicalDataTemplate for my requirement

Please see the attachment excel the data, I recieve from by database

1) Column ChildLevel shows the level were the data should be in RadTreeView
E.g., ChildLevel 5->4->3->2->1
See my post
http://www.telerik.com/community/forums/silverlight/treeview/radtreeview-hierarchal-temple.aspx

2) Column ParentID and ChildID indicates the association between the data

Can you provide me the RIA Entity Structure and RadTreeView HierarchicalDataTemplate for nested RadTreeView

Any update on the above post

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. 

Sincerely yours,
