title: Binding to a property defined in the parent user control's code-behind from the control template of child custom control
body: <p>I have a parent UserControl (<code>ParentUserControl</code>) which consists of a child CustomControl (<code>ChildCustomControl</code>). In the control template of my child custom control, I would like to bind to a property defined in the code-behind file, ParentUserControl.xaml.cs. If it is possible to do so, what would be the syntax for that?</p>
