Constructor

public CountryView()

{

InitializeComponent();

GridViewTableDefinition detailDefinition = new GridViewTableDefinition();

detailDefinition.Relation = new PropertyRelation("ID");

countryRadGridView.TableDefinition.ChildTableDefinitions.Add(detailDefinition);

}

.xaml

<telerikGridView:RadGridView Grid.Row="1" Margin="8,8,8,8"

x:Name="countryRadGridView"

UseAlternateRowStyle="True"

UseLayoutRounding="True"

ColumnsWidthMode="Fill"

AutoGenerateColumns="False"

ItemsSource="{Binding CountryList, Mode=TwoWay }">

<telerikGridView:RadGridView.Columns>

<telerikGridView:GridViewDataColumn HeaderText="ID" IsReadOnly="True" DataMemberBinding="{Binding ID, Mode=TwoWay}" />

<telerikGridView:GridViewDataColumn HeaderText="Country Name" IsReadOnly="True" DataMemberBinding="{Binding Name, Mode=TwoWay}" />

</telerikGridView:RadGridView.Columns>

<telerikGridView:RadGridView.HierarchyChildTemplate>

<telerikGridView:RadGridView Margin="45,8,30,8" UseAlternateRowStyle="True" x:Name="stateRadGridView" ItemsSource="{Binding StateList, Mode=TwoWay}" ColumnsWidthMode="Fill"

AutoGenerateColumns="False">

<telerikGridView:RadGridView.Columns>

<telerikGridView:GridViewDataColumn HeaderText="State ID" IsReadOnly="True" DataMemberBinding="{Binding ID, Mode=TwoWay}" Width="100" />

<telerikGridView:GridViewDataColumn HeaderText="State Name" IsReadOnly="True" DataMemberBinding="{Binding Name, Mode=TwoWay}" Width="130" />

</telerikGridView:RadGridView.Columns>

</telerikGridView:RadGridView>

</DataTemplate>

</telerikGridView:RadGridView.HierarchyChildTemplate>

</telerikGridView:RadGridView>

I have binded the CountryList to ItemsSource of countryRadGridView through ViewModel which work fine and only the country list get binded StateList doesnot get Binded on clicking the + . StateList contains data for sure.

CountryList is a list class of country

public class County

{

public int ID {get;set;}

public string Name {get;set;}

public List<State> StateList {get;set;}

}

public class State

{

public int ID {get;set;}

public string Name {get;set;}

}

Issue

StateList doesnot get Binded on clicking the +

Note:

I could not set ChildTableDefinitions in xaml Instead I have done it xaml.cs

when I tried this in xaml it did not support

<telerik:RadGridView.ChildTableDefinitions>

<telerik:GridViewTableDefinition />

</telerik:RadGridView.ChildTableDefinitions>
