The Congo.com Application

The application pictured in Figure 9-13 breathes life into many of the concepts presented in this chapter. Called Congo.com, it’s a virtual storefront for a fictitious online bookseller. Congo.com’s catalog consists of titles obtained from the SQL Server Pubs database. The main page, Congo.aspx, fetches the titles from the database and displays them in a DataGrid. Each row in the DataGrid contains an Add to Cart button that, when clicked, adds the corresponding book to a virtual shopping cart. Clicking the View Cart button at the top of the page shows the shopping cart’s contents, again using a DataGrid. This DataGrid has Remove buttons that delete items from the shopping cart.
