    Hi Telerik,

    I want to bind the two ComboBox with relationship table.
    but I can't bind second ComboBox.

    I send you Table and source code.

    Could you please send us the correct application.

            <riaControls:DomainDataSource x:Name="TestData" AutoLoad="True" QueryName="GetTest" >
                    <domain:HotelDomainContext />

            <TextBlock Grid.Row="0" Grid.Column="0" Text="Category :"  HorizontalAlignment="Left" Margin="5,2,5,2"/>
            <telerik:RadComboBox x:Name="Category" Grid.Row="1" Grid.Column="0" HorizontalAlignment="Left" VerticalAlignment="Top" MaxHeight="22"  Margin="5,2,5,2"  Width="160"    IsEditable="True" ItemsSource="{Binding Data,Source={StaticResource TestData}}" SelectedValuePath="Deneme" DisplayMemberPath="Name" Text="{Binding Name, Mode=TwoWay}"/>

            <TextBlock Grid.Row="0" Grid.Column="1" Text="Sub Category :"  HorizontalAlignment="Left" Margin="5,2,5,2"/>

            <telerik:RadComboBox x:Name="SubCategory" Grid.Row="1" Grid.Column="1" HorizontalAlignment="Left" VerticalAlignment="Top"     MaxHeight="22"  Margin="5,2,5,2"  Width="160"
     ItemsSource="{Binding ElementName=Category, Path=SelectedValue}"   Text="{Binding Name, Mode=TwoWay}"   IsEditable="True"/>

    Hi Mehmet,

    I reviewed your code and didn't notice anything wrong. The only thing I suspect may causes the problem is this:
    The SelectedValuePath should point the path to the sub categories of the selected category. You can find an attached working sample project.

    Hope this helps.

    Kind regards,
    the Telerik team
