PRO ASP.NET SR,

Book excerpt: Server Controls are a core part of the ASP.NET architecture. They are components that produce a user interface element that can be reused with ease. The standard controls that come with ASP.NET include the textbox, the button, the data and list controls, and some rich controls (for example, the calendar control). This book is designed to show you how to create your own controls, either from scratch, or based on existing controls. It is designed to be a complete reference on how to create Custom Server Controls. In essence, it's a definitive guide to what they're used for, how they are created, and the benefits that they can provide. The first part of the book concentrates on the code itself, and is designed to be editor-neutral, concentrating on the raw code involved in creating controls and making use of these controls. The second part of the book has more coverage of visual designers like Visual Studio .NET, talking about why using IDEs is so helpful, and examining the powerful features of Visual Studio .NET that are useful when creating custom controls.
