` typeof(object)

This was the device I used to bind to the datacontext of the ContentControl.

 public object MySelectedItem
    {
        get { return (object)GetValue(Property1Property); }
        set { SetValue(Property1Property, value); }
    }

            public static readonly DependencyProperty Property1Property
        = DependencyProperty.Register(
              "MySelectedItem",
              typeof(object),
              typeof(PromotionsMenu),
              new PropertyMetadata(false)
          );

Used like this:

 MySelectedItem = SomeEntity;

I discovered I could also use it like this:

 MySelectedItem = "some text";

And the contextcontrol would print some text as its context.

MySelectedItem = "";

works for a totally blank context.
