I don't know if you managed to solve your problem already. If you didn't here is how.

private DependencyObject FindChildControl<T>(DependencyObject control, string ctrlName)
    {
        int childNumber = VisualTreeHelper.GetChildrenCount(control);
        for (int i = 0; i < childNumber; i++)
        {
            DependencyObject child = VisualTreeHelper.GetChild(control, i);
            FrameworkElement fe = child as FrameworkElement;
            // Not a framework element or is null
            if (fe == null) return null;

            if (child is T && fe.Name == ctrlName)
            {
                // Found the control so return
                return child;
            }
            else
            {
                // Not found it - search children
                DependencyObject nextLevel = FindChildControl<T>(child, ctrlName);
                if (nextLevel != null)
                    return nextLevel;
            }
        }
        return null;
    }

usage is very simple, for example in my case

ComboBox cb= FindChildControl<ComboBox>(HUB_HC, "SemanaHC") as ComboBox;

Where HUB_HC is my HubSection name and SemanaHC is a combobox inside that HubSection witch is also inside of a StackPanel. It works for me and it's simple to use

The best way to deal with this is to have a user control inside the DataTemplate. And UserControl will have the Flipview, so you can easily access the flipview there.

To access any control inside a HubSection you can do something like this:

var sec = MyHub.Sections[2];
var btn = sec.FindVisualChild("MyButton") as Button;

EDIT: in order to use FindVisualChild extension method you have to use MyToolkit project. You can download it as a Nuget Package and see the project here.

Hope it helps! :D

EDIT 2: The code for FindVisualChild can be found here: https://mytoolkit.codeplex.com/SourceControl/latest#Shared/UI/FrameworkElementExtensions.cs
