    I have a grid that contains a field with a foreign key to a lookup table.  


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

            DataMemberBinding="{Binding Table2Id}"
            Header="Table2 Name"
            UniqueName="Table2Id" />

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

    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:

        <TextBlock Margin="2"
                   Text="{Binding ElementName=Table2sList,
                                  Converter={StaticResource table2Converter}}" />
        <telerik:RadComboBox Name="Table2sList"
                             SelectedValue="{Binding Table2Id}"
                <Interactivity:EventTrigger EventName="Loaded">
                    <gala:EventToCommand Command="{Binding DataContext.Table2sListLoadedCommand,
                                         CommandParameter="{Binding ElementName=Table2sList}"
                                         PassEventArgsToCommand="True" />

    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.

    Hello Jason,

     Generally the only Telerik component with lookup functionality is RadComboBox.
