datagridview bound to custom object

[sillysod]

I have a custom object which has several properties

i can bind to all the properties which are simple strings etc no problem

im struggling however where i have a property which is another custom object for example

if i had a collection of "Cars" and a car had the following properties

Make
Model
Reg
Owner

make / model / reg being strings and owner being of type "Person", and a "Person" had the following properties

Name
Age
Gender

When i bind the Cars collection to a datagridview i want the owner column to show the owners name, at the moment it will only show the name of owner object

Cheers
