Hi Krishna,

To enable hierarchy mode of the RadGridView control you have to define a ChildTableDefinition and add it to ChildTableDefinition collection of the RadGridView.TableDefinition.

            GridViewTableDefinition detailDefinition = new GridViewTableDefinition();
            detailDefinition.Relation = new PropertyRelation("Orders");
            radGridView1.TableDefinition.ChildTableDefinitions.Add(detailDefinition);
            radGridView1.ItemsSource = BuildCustomers();

GridViewDataColumns for the child grid will be created according to the information within the ChildTableDefinition object.

This code snippet above is taken from the "Property Hierarchy" examle. Take a look at the "Property Hierarchy" and the "Custom Hierarchy" examples available at http://demos.telerik.com/wpf/ and in your offline sample apps. They contain the working code for a scenario that looks identical to yours.

For details on creating hierarchy you can go through the http://www.telerik.com/help/wpf/gridview-fundamentals-hierarchical.html help topic.

Hope this will help.
