Hello anoop,

When you create relation between parent/child templates, you must add it to RadGridView Relations collection.

gridView.Relations.Add(relation);

Please view our Examples demo application - RadGridView >> Hierarchy section. For additional information about the process of manually configuring a hierarchy in RadGridView, please refer to our online help.

Sincerely yours,
