this is the xaml:

<Window x:Class="SimaClient.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"
    Title="Sima Client" Height="300" Width="400" WindowStyle="ToolWindow">
    <Grid>
        <telerik:RadGridView Name="RadGridView1" ShowGroupPanel="False" IsReadOnly="True" AutoGenerateColumns="False" ColumnsWidthMode="Fill">

            <telerik:RadGridView.ChildTableDefinitions>
                <telerik:GridViewTableDefinition />
            </telerik:RadGridView.ChildTableDefinitions>

            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding ID}" Header="ID" Width="100" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Header="Name"  Width="200"/>
            </telerik:RadGridView.Columns>

            <telerik:RadGridView.HierarchyChildTemplate>
                <DataTemplate>
                    <telerik:RadGridView x:Name="RadGridView1" AutoGenerateColumns="False" ItemsSource="{Binding Routes}" ShowGroupPanel="False" IsReadOnly="True">
                        <telerik:RadGridView.Columns>
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding ID}" Header="Route ID" />
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Header="Route Name" />
                            <telerik:GridViewDataColumn DataMemberBinding="{Binding WayPointsNum , Mode=OneWay }" Header="Number of WP" />
                        </telerik:RadGridView.Columns>
                    </telerik:RadGridView>
                </DataTemplate>
            </telerik:RadGridView.HierarchyChildTemplate>

        </telerik:RadGridView>
    </Grid>
</Window>

Hi,

You can check this blog post for more info:
http://blogs.telerik.com/vladimirenchev/posts/09-10-16/how_to_silverlight_grid_hierarchy_load_on_demand_using_mvvm_and_ria_services.aspx

The post is for Silverlight however the approach and the grid XAML is exactly the same in WPF since our code is completely shared between both platforms.

All the best,
