I have a grid that contains a field with a foreign key to a lookup table.  
 
Table1
    Id
    Name
    Table2Id

Table2
    Id
    Name

Using a normal grid row I would normally display the Table2Id using a RadComboBox like follows to display the text:

<telerik:GridViewComboBoxColumn
        MinWidth="80"
        DataMemberBinding="{Binding Table2Id}"
        DisplayMemberPath="Name"
        Header="Table2 Name"
        IsReadOnly="True"
        SelectedValueMemberPath="Id"
        ShowColumnWhenGrouped="False"
        TextWrapping="NoWrap"
        UniqueName="Table2Id" />

Now I want to go from a normal row to a custom row like the one in the demos:

http://demos.telerik.com/silverlight/#GridView/CustomRowLayout

Currently I am getting the text for the name by doing a round about way:

Basically I have a StackPanel that contains a TextBlock and a RadComboBox making the RadComboBox that is bound to the datasource invisible and setting the text of the TextBlock to the SelectedItem of the RadComboBox:

<StackPanel>
    <TextBlock Margin="2"
               HorizontalAlignment="Left"
               VerticalAlignment="Center"
               Text="{Binding ElementName=Table2sList,
                              Path=SelectedItem,
                              Converter={StaticResource table2Converter}}" />
    <telerik:RadComboBox Name="Table2sList"
                         HorizontalAlignment="Left"
                         VerticalAlignment="Center"
                         SelectedValue="{Binding Table2Id}"
                         SelectedValuePath="Id"
                         Visibility="Collapsed">
        <Interactivity:Interaction.Triggers>
            <Interactivity:EventTrigger EventName="Loaded">
                <gala:EventToCommand Command="{Binding DataContext.Table2sListLoadedCommand,
                                                       ElementName=View}"
                                     CommandParameter="{Binding ElementName=Table2sList}"
                                     PassEventArgsToCommand="True" />
            </Interactivity:EventTrigger>
        </Interactivity:Interaction.Triggers>
    </telerik:RadComboBox>
</StackPanel>

The problem with this route it that it takes a lot of work to hook the commands up and get the data loaded.  Is there any other way to do that will be much more maintainable and easier to setup?  I guess what I am looking for is the easiest way to get the foreign key data in the custom row.

On the demo page above it would be like the Title field coming from a look up table instead of text from the main data source.


Thanks,

Jason

Hello Jason,

 Generally the only Telerik component with lookup functionality is RadComboBox.
