Professional ASP.NET 3.5 in C# and Visual Basic Part 46

Professional ASP.NET 3.5 in C# and Visual Basic Part 46. 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 span id DataList1_ctl00_CompanyNameLabel Alfreds Futterkiste span br br td tr tr td CompanyName span id DataList1_ctl01_CompanyNameLabel Ana Trujillo Emparedados y helados span br br td tr -- Code removed for clarity -- table Although this table layout is the default you can change this so that the DataList control outputs span tags instead.
