About the Authors
Chris Ullman
Chris Ullman is a freelance Web developer and technical author who has spent many years stewing in
ASP/ASP.NET, like a teabag left too long in the pot. Coming from a Computer Science background, he

started initially as a UNIX/Linux guru, who gravitated towards MS technologies during the summer of
ASP (1997). He cut his teeth on Wrox Press ASP guides, and since then he has written over 20 books,
most notably as lead author for Wrox's bestselling Beginning ASP/ASP.NET series, and has contributed
chapters to books on PHP, ColdFusion, JavaScript, Web Services, C#, XML and other Internet-related
technologies too esoteric to mention, now swallowed up in the quicksands of the dot.com boom.
Quitting Wrox as a full-time employee in August 2001, he branched out into VB6 programming and ASP
development, maintaining a multitude of sites from , his "work" site, to
, a selection of his writings on music and art. He now divides his time
between being a human punchbag for his 29-month-old son Nye, composing electronic sounds on bits
of dilapidated old keyboards for his music project Open E, and tutoring his cats in the art of peaceful
co-existence, and not violently mugging each other on the stairs.
Chris Ullman contributed Chapters 1, 14, 15, 16, 17, and Appendix E to this book.

John Kauffman
John Kauffman was born in Philadelphia, the son of a chemist and a nurse. He received his degrees from
The Pennsylvania State University, the colleges of Science and Agriculture. His early research was for
Hershey foods in the genetics of the chocolate tree and the molecular biology of chocolate production.
Subsequently, he moved to the Rockefeller University, where he cloned and sequenced DNA regions that
control the day and night cycles of plants.
Since 1997, John has written ten books, six of which have been on the Amazon Computer Best Seller
List. His specialty is programming Web front-ends for enterprise-level databases.
In his spare time, John is an avid sailor and youth sailing coach. He represented the USA in the sailing
World Championship of 1985 and assisted the Olympic teams of Belgium and China in 1996. He also
enjoys jazz music and drumming and manages to read the New Yorker from cover-to-cover each week.
My portions of this book are dedicated to the instructors of two drum and bugle corps. These men
taught me about precision, accuracy, and discipline: Ken Green and John Flowers of the Belvederes 1976
and Dennis DeLucia and Bobby Hoffman of the Bayonne Bridgemen 1978.
John Kauffman contributed Chapters 2, 3, 4, 5, 6, and Appendix B to this book.

husband James. While she's most at home in the world of the Web, she's recently been working with the
.NET Compact Framework. In her spare time, Chris spends much of her time playing with beta
technologies, and then attempting to write about them.
Chris has contributed many chapters to a variety of books, including Beginning ASP.NET (Wrox Press),
Beginning Dynamic Websites with ASP.NET Web Matrix (Wrox Press), and most recently, A Programmer's
Guide to SQL (Apress).
When she gets away from computers, Chris enjoys travel, especially when it involves driving along
narrow winding roads to get to out-of-the-way parts of Scotland. She dreams of building her own house
somewhere where she can keep a cat.
Chris Hart contributed Chapters 10, 11, 12, 13, and Appendices C and D to this book.

Dave Sussman
Dave Sussman is a writer, trainer, and consultant, living in the wilds of the Oxfordshire countryside.

English, Math, and Guitar, directed, crewed, acted in, and produced several plays and short films, been a
film and music columnist for four years, co-founded ASPToday.com, rewritten his own at HMobius.com
several times, opened an office in India, variously edited, reviewed, and written pieces of over 40
programming books, qualified as a sound engineer, and consumed enough caffeine in his lifetime to
keep most of China awake for a week. Occasionally, he sleeps. Sometimes. Contact him at

"With deep-felt love to Jane, and in memoriam to John Kauffman's father."

Dan Maharry contributed Chapters 5 and 6 to this book.

Introduction
ASP.NET is a radical update of Microsoft's Active Server Pages (ASP). ASP.NET is a powerful server based
technology designed to create dynamic and interactive HTML pages on demand for your Web site or
corporate intranet. Its design improves upon nearly every feature of classic ASP, from reducing the
amount of code you need to write to giving you more power and flexibility.
ASP.NET is a key element in Microsoft's .NET Framework, providing Web-based access to the
immensely powerful .NET development environment. It allows us to create Web applications in a new,
flexible way by placing commonly used code into reusable controls of various kinds that can fire events
initiated by the users of a site.
ASP.NET branches out into many other technologies, such as Web services, ADO.NET, custom controls,
and security. We will briefly touch upon its relationship with these fields throughout the book to provide
a solid, comprehensive understanding of how ASP.NET can benefit your work in a practical way.
ASP.NET 1.1 itself is a fairly light update to the complete wholesale changes that occurred in ASP.NET
1.0. This book by and large covers features that are available in both 1.0 and 1.1, but it covers the
pertinent new features of 1.1 in additional depth, which will be of interest to both the novice and
experienced users. So if you are already running ASP.NET 1.0, you will be expected to upgrade to 1.1.
By the end of this book you will be familiar with the anatomy of ASP.NET 1.1 and be able to create
powerful, secure, and robust Web sites that can collect and work with information in a multitude of
ways to the benefit of both you and your users.

Who Is This Book For?
The purpose of this book is to teach you from scratch how to use ASP.NET to write Web pages and Web
applications in which content can be programmatically tailored each time an individual client browser
calls them up. This not only saves you a lot of effort in presenting and updating your Web pages, but
also offers tremendous scope for adding sophisticated functionality to your site. As ASP.NET is not a
programming language in its own right, but rather a technology (as we shall explain in the book), we
will be teaching some basic programming principles in Chapters 2 to 7 in C#, our chosen language for
implementing ASP.NET.
This book is therefore ideal for somebody who knows some basic HTML but has never programmed

before, or somebody who is familiar with the basics of old style ASP, but hasn't investigated ASP.NET in
any detail. If you are an experienced programmer looking for a quick crash course on ASP.NET, or
somebody who's worked extensively with ASP, we suggest that you refer to Professional ASP.NET 1.1
Special Edition, Wiley ISBN: 0-7645-58900 instead, as you'll most likely find that the early chapters here
just reiterate things you already know. If are not familiar with HTML, then we suggest that you master
the basics of building Web pages before moving on to learning ASP.NET.

Introduction

What Does This Book Cover?
This book teaches everything the novice user needs to know, from installing ASP.NET and the relevant
bits and pieces to creating pages and putting together the concepts to create a whole application using
ASP.NET 1.1.
Although ASP.NET 1.1 isn't a huge update on version 1.0, this book has been considerably overhauled
since edition 1.0. Plenty of the old chapters have been removed and many new ones introduced. We've
removed three chapters because we wanted to simplify the experience of learning ASP.NET. We've
created a brand new case study – an amateur sports league Web site – which is then used throughout
the latter chapters in the book to provide a more practical guide on how to implement ASP.NET
applications.
If you see the previous edition, you will find this one to be more cohesive, aimed towards the complete
novice and the developer with some ASP experience, and written with the benefit of hindsight from
experienced developers who have have been employed in creating ASP.NET applications. We trust that
you will find it a great improvement over the last, just as every new edition should be.
In the course of this book you will learn:


What is ASP.NET




How to install ASP.NET and get it up and running



The structure of ASP.NET and how it sits on the .NET Framework



How to use ASP.NET to produce dynamic, flexible, interactive Web pages



Basic programming principles such as variables, controls structures, procedural programming,
and objects



How to use ASP.NET to interface with different data sources, from databases to XML
documents



What ready-made controls ASP.NET offers for common situations



How to create your own controls




How to debug your ASP.NET pages



How to deal with unexpected events and inputs



How to create your own Web application



How to integrate your applications with Web services and how to create your own



Some simple security features and how to create a login for an application

How This Book Is Structured
Here is a quick breakdown of what you will find in this book:


Chapter 1 – Getting Started with ASP.NET: In the first chapter, we introduce ASP.NET and look
at some of the reasons that you'd want to use server-side code for creating Web pages as well as
the technologies that are available to do so. This done, we spend the bulk of the chapter
