Hi there,
Since this question is not directly related to the book, you're better off posting in a more general ASP.NET category here:

That said, there are no built-in controls for a shopping cart. You can however, use controls such as the GridView, DataList or ListView as they can display rows of data. You're still responsible for assigning the data you want to display as well as adding products to the cart. In my book ASP.NET 2.0 Instant Results you find a working example.
In addition, you can search Google for ready-made (commercial) shopping carts.
Cheers,
Imar
