{Binding Name.Length}

Binds the Length property of the Name property of the object in the DataContext.

RelativeSource Binding

The relative source mode of the binding extension helps you to bind to an object with an relative relation to you. You don't know your or its abolute position, but you know if it's the previous or next item, two levels above you or of an specific type.

{Binding RelativeSource={RelativeSource Self}}

Bind to your self. Helpful to access your own properties.

{Binding Text, RelativeSource={RelativeSource Self}}

Binds Text property of the target element.

{Binding IsSelected, RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type ListBoxItem}}}
