Murach's ASP.NET Web Programming with VB.NETThis chapter teaches you the basics of developing custom server controls. Although these are similar to user controls (covered in chapter 10), they’re more powerful. They’re also more difficult to develop because Visual Studio doesn’t provide a designer interface to help you create them. |
