Bind from XAML to a local property in code-behind

When I learned WPF I couldn´t figure out how to create a simple binding from my XAML to some property in my code-behind file. Now when I know I thought that I should share this small piece of knowledge and spare you the frustration that I had.

One way to create a binding is to bind to another element in your XAML-file. E.g. Text=”{Binding SomeProperty, ElementName=MyOtherElement}” where SomeProperty is a property in your MyOtherElement. MyOtherElement is the name (x:Name) of an element in your XAML-file. With this knowledge we just set a name on our root element (Window, Page, UserControl or whatever) x:Name="myRoot" and then refer to that name in ElementName. E.g Text="{Binding MyLocalProperty, ElementName=myRoot }". The MyLocalProperty is then a property in our code-behind file. This can be a standard property or a dependency property.
