Hello Telerik Team,

I managed to make RadGridView show multiple related tables (LINQ to SQL) by approach used in FirstLook sample (create GridViewTableDefinition and TableRelation). If I add two table definitions it works OK (besides showing empty table if no related record exists).

1. RadGridView (Attached Image which describes how is related tables are used via TabControl in your WPF Demo Application)
2. Telerik_WPFControls_Demo_DataGrid (Attached Image which describes how is related tables are used via TabControl in your WPF Demo Application)
3. My_TabControlStylingPic (The style that I want to use )
4. CurrentRelatedTabelLook( The current look of the related table)

What I want to do is to change the look in (Image 4) by (Image 3)

5. The following code (Is the My own XAML code of My_TabControlStylingPic - as attached) - It was designed using Blend. Here is the code:

telerikNavigation:RadPanelBar ItemsSource="{Binding Path=Sections}"

    ItemTemplate="{StaticResource SectionsTemplate}"/>

And I have the two following templates:

DataTemplate x:Key="CommandsTemplate">

    <StackPanel Orientation="Vertical" Margin="5">

        <TextBlock Margin="2,6">

            <Hyperlink Command="{Binding Path=Command}">

                <TextBlock Text="{Binding Path=DisplayName}" />

            </Hyperlink>

        </TextBlock>

    </StackPanel>

</DataTemplate>

<DataTemplate x:Key="SectionsTemplate">

    <telerikNavigation:RadPanelBarItem ItemsSource="{Binding Path=Commands}" ItemTemplate="{StaticResource CommandsTemplate}">

        <telerikNavigation:RadPanelBarItem.Header>

            <TextBlock Text="{Binding Path=SectionName}" />

        </telerikNavigation:RadPanelBarItem.Header>

    </telerikNavigation:RadPanelBarItem>

</DataTemplate>

The result is that there is like an other control in the sections bars, and I have to click on it (the arrow is not working) to see the list of commands, but instead of the commands being simple links, they appear as a RadPanelBar, with an arrow on the right which is doing nothing.

What am I doing wrong?

Best regards,
Daniel Varrin
