If you want to use Binding you need to expose the usercontrol(s) as a DependencyProperty - Can access proprty in XAML or code behind.
AS an example you can expose the radiobutton as

C#

public static readonly DependencyProperty Radio1Property = DependencyProperty.Register("Radio1", typeof(RadioButton),
typeof(YourUserContol),
new PropertyMetadata());

        public RadioButton Radio1
        {
            get { return (RadioButton)this.GetValue(Radio1Property); }
            set { this.SetValue(Radio1Property, value); }
        }

or you can expose the controls as CLR-Public properties and you can then access in your code behind.

I hope this helps.
