radgridview bind complex object

[Anatol]

Hello

I have complex class like this:

class person
    {
        string name;
        car Car;
    }
    
    class car
    {
        string model;
        string number;
    }

////////////////////////

 ObservableCollection<person> persons  = getAllPerson() ;

mainDG.ItemSource = persons;

////////////////////////

How can I bind it to my RadgridView?

<telerik:RadGridView x:Name="mainDG" Margin="259,0,5,5" AutoGenerateColumns="False" >
                        <telerik:RadGridView.Columns>

                                  <telerik:GridViewDataColumn Header="Car number" DataMemberBinding="{Binding Car.number}"/>//How can I bind it?

                       </telerik:RadGridView.Columns>

</telerik:RadGridView>
