VS 2010 Using DataNavigator And One-to-many Relationships

I'm using a Data navigator to navigate (duh) through some records that my BLL fetches from the DAL. I use DataTables to fetch the recrods. Some of such records have one to many relationships. Lets say for example a person has may telephone numbers and my navigator goes through all the persons whose name are Joe. So I manage to show all the Joes through my navigator in the controls but I want to be able to show all their telephone numbers also. Persons is one Table, TelephoneNumbers is another. Each Telephone number has the person it belongs to. I access them through a DataSet and my BLL controllers return DataTables in their search methods, as said.
