Professional ASP.NET 3.5 in C# and Visual Basic Part 48. Building on the revolutionary ASP.NET 2.0 release, ASP.NET 3.5 adds several key new developer features including AJAX, LINQ, and a new CSS designer in Visual Web Developer 2008. The dramatic reduction in code that developers realized from the more than 50 new server controls in ASP.NET 2.0 now allows developers the time to make their applications more interactive with AJAX, to work with data in their preferred language with LINQ, and to build visually attractive and consistent standards-based sites with CSS. . | Chapter 8 Data Managementwith ADO.NET After you close the Add Table dialog box you see a visual representation of the table that you selected in the Query Builder dialog box see Figure 8-19 .

After you are finished using the wizard notice there is a visual representation of the CustomersTableAdapter that you just created see Figure 8-21 . Along with that is a DataTable object for the Customers table. The TableAdapter and the DataTable objects that are shown on the design surface are also labeled with their IDs. Therefore in your code you can address this TableAdapter that you just built by referring to it as CustomerOrdersTableAdapters.CustomersTableAdapter. The second TableAdapter that queries the Orders table is then shown and referred to as CustomerOrders-TableAdapters.OrdersTableAdapter. Figure 8-21 After you have the two .
