Question

In a WPF 4 UserControl I could define the bindings of a sub control in XAML something like this …

...
    <ComboBox 
        ItemsSource="{Binding CBItems, 
                      RelativeSource={RelativeSource AncestorType=UserControl}}"
        ...              
    />
...

where CBItems is a property defined in the code behind of the UserControl.

However this format isn’t available in Windows 8 Metro – RelativeSource does not have a member AncestorType.

How can I do this type of binding in Windows 8?

Answer 1

It looks as though TemplatedControl rather than UserControl is the way to go to create reusable compound components for Windows 8 metro development.
