Binding a textbox to an object

Let's say I have two objects in an entity-framework:

public class Person
{
     public int key;
     public string Name;
     public Address HomeAddress;
}

public class Address
{
     public int key;
     public string street;
     public string city;
}
    

In my report, I want a textbox to be able to display the fields from the HomeAddress object inside of Person.  How can I do that?  I can see the fields for Person in the Report Editor, but cannot access the fields for the Address object in the interface.
