How can I tell my DataTemplate to bind to a property in the PARENT ViewModel?

Question

I\'ve got the following MainView.xaml file that works well as a MVVM menu switcher. I\'ve got these pairs:

• Page1View / Page1ViewModel

Answer 1

The answer is this:

<DataTemplate x:Key="CodeGenerationMenuTemplate">
    <MenuItem 
        Header="{Binding Title}" 
        Command="{Binding DataContext.SwitchPageCommand,
    RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Menu}}}" 
        CommandParameter="{Binding Title}"/>
</DataTemplate>

I just saw that Nir had given me the syntax to solve the above issue on this question: What is the best way in MVVM to build a menu that displays various pages?.
