Access Frame Control - contained within DataTemplate of HubSection

Question

I am writing to learn how best a Frame element, defined within the DataTemplate of a HubSection, can be programmatically accessed from C# - for an upcoming Windows 8.1 project; 

The new Hub App template is being utilized, with Xaml and C# contained in the below snippets - the code of "return this.FrameContent" is not recognized;

Thanks in advance for insight, guidance;

 <HubSection Width="520" x:Uid="Section2Header" Header="Section 2" Loaded="HubSection_Loaded">

                <DataTemplate x:Name="PodDataTemplate">
                    <Frame x:Name="FrameContent" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch"/>
                </DataTemplate>
                
            </HubSection>

public Frame GetFrameContent()
        {
            return this.FrameContent;
        }

Answer 1

x:Name'd elements aren't findable in this manner in DataTemplates.  If this is critical to your scenario, instead of putting the content directly in the hub section you could put it in a usercontrol and put that UC in the hub section.

Answer 2

Thanks Tim;

Can a code sample be provided to access the Frame, and/or User Control from C#;

Utilizing the below Xaml code, I am not able to reference the Frame, User Control from C#;

Thanks in advance for insight, guidance;

 <HubSection Width="500" x:Uid="Section1Header" Header="Section 1">
                <DataTemplate>
                    <UserControl x:Name="ucTest">
                        <Frame x:Name="frmTest" ></Frame>                        
                    </UserControl>
                </DataTemplate>
            </HubSection>

Answer 3

It wouldn't be literally how you have it but rather you'd have a file foo.xaml that contained your Frame and then in the page that has the hub:

<HubSection>
  <DataTemplate>
    <local:MyUserControl />

Now in your user control you'd have to write some code to get at whatever objects you need and perform the tasks.
