WPF Bind TextBlock to Window's Title

I have a TextBlock on my main window. I would like to bind it's text to the window's title .. eg: myWindow.Title.

This has been bugging me all night开发者_如何学Python, and I have Googled to death, any help is appreciated.

Thanks.

The simplest way is just to bind back to the parent window:

<TextBlock Text="{Binding Title,RelativeSource={RelativeSource FindAncestor,AncestorType=Window}}"  />
