Best way to display data in a treeview

Hi, I need to display a self referencing table ( < 500 records) in a treeview but not sure what is the best way to do it.
Currently i'm thinking of  building a nested XML using dataset relationships, then assign it to the Treeview control. Thing is I'm quite new to ASP so still trying to find my feet. any suggestions would greatly be appreciated.
 
thanks.
