XAML - Access to the parent window of a page from this page

Hi everybody,

I have a Page that is hosted in a Window.
I would like to access to Window's properties from the XAML code of the Page (not from the .cs code, I already found the solution for that).

<Label Content="{Binding Title, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}"/>

Any idea ?

Thanks in advance for your suggestions.
