Binding a RadRadioButton

I'm trying to bind a set of RadRadioButtons to object properties: Here is the binding:

rbOwnOrRentOwn.DataBindings.Add("IsChecked", prevAddress, nameof(prevAddress.OwnOrRentOwn), false, DataSourceUpdateMode.OnPropertyChanged);

rbOwnOrRentRent.DataBindings.Add("IsChecked", prevAddress, nameof(prevAddress.OwnOrRentRent), false, DataSourceUpdateMode.OnPropertyChanged);

and here are the properties:

        public bool OwnOrRentOwn

        {
            get => _ownOrRentOwn;
            set
            {
                _ownOrRentOwn = value;
                OnPropertyChanged(nameof(OwnOrRentOwn));
            }
        }

        public bool OwnOrRentRent
        {
            get => _ownOrRentRent;
            set
            {
                _ownOrRentRent = value;
                OnPropertyChanged(nameof(OwnOrRentRent));
            }
        }

When I bind like this the object properties are not set when the buttons are selected/deselected.

The docs say that CheckState is one way to go but these enums are defined in System.Windows.Forms. This would mean I need to introduce the System.Windows.Forms into my business layer. Is this what I need to do or is there a better way.

This should be just a simple data binding.

Thanks
