This property is useful when you want to bind to the property of another element in your application. For example, if you want to use a Slider to control the height of another control in your application, or if you want to bind the Content of your control to the SelectedValue property of your ListBox control.
By default, bindings inherit the data context specified by the DataContext property, if one has been set. However, the property is one of the ways you can explicitly set the source of a Binding and override the inherited data context. For more information, see How to: Specify the Binding Source.
The Source and RelativeSource properties of the Binding class also enable you to set the source of the binding explicitly. However, only one of the three properties, , Source, and RelativeSource, should be set for each binding, or a conflict might occur. This property throws an exception if there is a binding source conflict.
