This Wrox Blox empowers developers to develop ASP.NET AJAX controls by giving them a look "under the hood" of AJAX controls. While this Wrox Blox focuses on Visual Studio 2008 and .NET 3.5, developers should know that the concepts for creating custom controls in Visual Studio 2005 and .NET 2.0 with ASP.NET AJAX 1.0 are very similar. Visual Studio 2008 offers many improvements concerning JavaScript editing/debugging, and .NET 3.5 includes ASP.NET AJAX right out of the box, simplifying the install to get AJAX up and running.

This Wrox Blox takes developers gradually through creating a custom ASP.NET AJAX control. JavaScript is essential for writing ASP.NET AJAX controls, but quite a few developers still struggle in this area. Given this fact, this Wrox Blox takes a compressive look at JavaScript and the improvements that the Microsoft AJAX Library provides to client-side development, giving readers the skills they need to delve straight into creating a “news scroller” type control from start to finish with step-by-step instructions throughout.

Delivering rich, Web 2.0-style experiences has never been easier. This book gives you a complete hands-on introduction to Microsoft ASP.NET AJAX 1.0, the new framework that offers many of the same benefits for Ajax development that ASP.NET provides for server-side development. With Programming ASP.NET AJAX, you'll learn how to create professional, dynamic web pages with Ajax in no time.
Loaded with code and examples that demonstrate key aspects of the framework, this book is ideal not only for ASP.NET developers who want to take their applications a step further with Ajax, but for any web developers interested in ASP.NET AJAX, no matter what technology they use currently. That includes JavaScript programmers who would like to avoid the headaches of writing cross-browser code.
Programming ASP.NET AJAX offers you:

• A high-level overview of the ASP.NET AJAX framework
• Functional code that you can cut and paste for use in your own applications
• The essentials of JavaScript and Ajax to help you understand individual technologies used by the framework
• An organization that reflects the framework's packages, including Extensions, Control Toolkit, the Futures CTP, and the AJAX Library
• Sidebars throughout the book that identify and propose solutions to potential security breaches
• Ways to use the standards-based AJAX Library with other platforms, such as PHP
• A complete chapter on the UpdatePanel control for making individual parts of a web page independently updateable -- one of the framework's most important elements

Released previously as Programming Atlas to cover the beta version of the Microsoft framework, this edition is fully up-to-date and expanded for the official 1.0 release of ASP.NET AJAX. Written by Christian Wenz -- Microsoft MVP for ASP/ASP.NET and AJAX Control Toolkit Contributor -- Programming ASP.NET AJAX contains many hard-to-find details, along with a few unofficial ways to accomplish things.

ASP.NET revolutionized Web application development. The platform handles many of the complexities of creating Web applications. Now ASP.NET AJAX takes the development platform even further. The lines between rich client applications and traditionally less interactive browser-based applications are being further blurred with the use of this technology.

The ASP.NET AJAX Library brings object-oriented programming to JavaScript development for modern browsers, and the ASP.NET AJAX Extensions makes it easy to write rich Web applications that communicate with the Web server asynchronously. Again, the complexities are made easy by using ASP.NET.

The new server controls that are part of ASP.NET AJAX make it simple to designate parts of the page to be updated automatically without making the user pause and wait while the data is refreshed. You can have partial page updates without writing a single line of code. Other new controls let you alert the user that background work is happening and designate regular intervals at which updates occur. In addition, the ASP.NET AJAX Control Toolkit makes it easy to make your user interface really come to life with animations, modal dialogs, transition effects, and more.

Ajax is definitely the hot buzzword in the Web application world at the moment. Ajax is an acronym for Asynchronous JavaScript and XML and, in Web application development, it signifies the capability to build applications that make use of the XMLHttpRequest object.

The creation and the inclusion of the XMLHttpRequest object in JavaScript and the fact that most upper-level browsers support the use of this object led to creation of the Ajax model. Ajax applications, although they have been around for a few years, gained greater popularity after Google released a number of notable, Ajax-enabled applications such as Google Maps and Google Suggest. These applications demonstrated the value of Ajax.

Shortly thereafter, Microsoft released a beta for a new toolkit that enabled developers to incorporate Ajax features in their Web applications. This toolkit, code-named Atlas and later renamed ASP.NET AJAX, makes it extremely simple to start using Ajax features in applications today.

Prior to Visual Studio 2008, the ASP.NET AJAX product used to be a separate application that developers were required to install on their machine and the Web server that they were working with. This release gained in popularity quite rapidly and has now been made a part of the Visual Studio 2008 offering. Not only is it a part of the Visual Studio 2008 IDE, the ASP.NET AJAX product is also baked into the .NET Framework 3.5. This means that in order to use ASP.NET AJAX, developers are not going to need to install anything if they are working with ASP.NET 3.5.

Overall, Microsoft has fully integrated the entire ASP.NET AJAX experience in that developers can easily use Visual Studio and its visual designers to work with your Ajax-enabled pages and even have the full debugging story that they would want to have with their applications. Using Visual Studio 2008, developers are now able to debug straight into the JavaScript that they are using in the pages.

In addition, it is important to note that Microsoft focused a lot of attention on cross-platform compatibility with ASP.NET AJAX. Developers will find that the Ajax-enabled applications that they build upon the .NET Framework 3.5 are able to work within all the major up-level browsers out there (e.g., FireFox and Opera).

This book is aimed at experienced ASP.NET developers looking to add AJAX to their applications, and experienced Web developers who want to move to using ASP.NET and AJAX together.

In this book, I assume that you already have an understanding of how ASP.NET works. For an in-depth discussion of ASP.NET, I recommend Professional ASP.NET 3.5 by Bill Evjen, et al. (Wrox, 2008). The focus here is on how you can extend ASP.NET applications to update portions of the page asynchronously and to add richer UI elements to a page. ASP.NET AJAX makes it easy to enrich your existing application or to design a new application to provide a better experience for users. The differences among modern browsers have been abstracted, allowing you to write to a common set of APIs and trust that the user will get the correct behavior whether they are using Internet Explorer, Firefox, or Safari.

If you know how to author ASP.NET pages, you can easily start using the Microsoft AJAX library to manipulate the browser’s Document Object Model and communicate with the server to update the user’s view of data without forcing them to wait for the entire page to be refreshed.

This book covers ASP.NET 3.5 AJAX. It does not cover ASP.NET 3.5, on which ASP.NET AJAX is built. The examples lead you from the core of what is included in the ASP.NET AJAX Library through the core controls you would first start using. You build on that using the core JavaScript library and the ASP.NET AJAX Toolkit before covering debugging, deployment, and custom control development.

The ASP.NET 3.5 release includes the Microsoft AJAX Library as well as the server controls that can be used in ASP.NET pages to extend applications, making them more rich and interactive. It does so by leveraging the ASP.NET AJAX Library, which is JavaScript that runs in the browser. The server controls and JavaScript Library work together to let you update HTML with data obtained asynchronously from the server. The ASP.NET application services are exposed to JavaScript classes in the ASP.NET AJAX Library, making authentication and personalization accessible from the browser.

Chapter 1 introduces you to ASP.NET AJAX. This book discusses the need for AJAX Libraries and explain how ASP.NET AJAX compares to other AJAX Libraries. You will see how ASP.NET AJAX is composed of client and server pieces and that you can use the client library with any server platform you choose. In Chapter 2, the focus is on the most popular and easily applied feature of ASP.NET, the UpdatePanel control. This control allows you to automatically update portions of a page asynchronously, without subjecting the user to a visible pause while the page refreshes. Chapters 3 and 4 give you some key information about working with JavaScript and how the ASP.NET AJAX Library makes development with JavaScript easier. The book then works through several key features, including control of script resources and working with the ScriptManager control in Chapter 5, the new ASP.NET 3.5 ability to work with the back button in Chapter 6, and the ASP.NET AJAX Toolkit in Chapter 7 and all it has to offer for creating rich user interfaces. The next chapter, Chapter 8, looks at how to use ASP.NET’s application services (such as the Membership and Role management systems) with ASP.NET AJAX. Chapter 9 looks at networking objects. Chapter 10 looks at working with animations in ASP.NET AJAX. Chapter 11 shows you how to develop custom AJAX controls. Chapters 12, 13, and 14 shows the reader how to incorporate Ajax in some other ASP.NET core features such as Web Parts, localization, and state management. Chapter 15 looks at what is required to test and debug Ajax applications, and finally, Chapter 16 explores how to deploy ASP.NET AJAX applications.

Ajax has revolutionized the way users interact with web pages today. Gone are frustrating page refreshes, lost scroll positions and intermittent interaction with a web site. Instead, we have a new generation of fast, rich, and more intuitive web applications. The ASP.NET AJAX framework puts the power of Ajax into the hands of web developers. ASP.NET AJAX, formerly called Atlas, is a new free framework from Microsoft designed to easily add Ajax features to ASP.NET applications. With this technology, ASP.NET developers can easily build more interactive and highly-personalized web applications that work across all most popular browsers.

ASP.NET AJAX in Action is a fast-paced, example-rich tutorial designed for ASP.NET web developers and written by ASP.NET AJAX experts Alessandro "Garbin" Gallo, David Barkol, and Rama Krishna Vavilala. This book introduces you to Ajax applications and to the ASP.NET AJAX technology. Beginners will appreciate the clear explanations of key ideas and terminology. Intermediate and advanced ASP.NET developers will find a no-nonsense learning source and well-organized reference.

ASP.NET AJAX in Action offers a rich set of examples and meticulous explanations. The extensive code samples are accompanied by accurate and rigorous explanations of the concepts behind development with ASP.NET AJAX. In this book, you will discover how to use

This Wrox Blox gives developers a hands-on look at some of the commonly used AJAX Control Toolkit controls, focusing on the CollapsiblePanel, Accordion, Tabs, ModalPopup, TextboxWatermark, AutoComplete, and CascadingDropDown. Developers also gain the tools they need to effectively use and understand the other controls found in the Toolkit. The starting point is an introduction to ASP.NET AJAX discussing the ASP.NET AJAX Extensions 1.0 and AJAX in .NET 3.5, laying the groundwork for understanding how all the pieces of the ASP.NET AJAX Framework interoperate. The introduction focuses on controls in the Extensions such as the ScriptManager, which is required for most of the AJAX Toolkit Controls, leaving readers with an understanding of the client-side enhancements found in the Microsoft AJAX Library.

The next step is getting the ASP.NET AJAX Extensions installed and running properly as well as installing the AJAX Control Toolkit. This section also offers troubleshooting tips for common issues.

Finally, developers will venture into the world of the ASP.NET AJAX Control Toolkit. Under this section, each of the controls listed will focus on using the ASP.NET AJAX Control Toolkit with real-world tasks in mind, not just boilerplate examples. Common tasks include theming, comparison against the UpdatePanel, dynamically creating controls, venturing into client-side (JavaScript) source code, and recommended usages.

Professional Ajax 2nd Edition provides a developer-level tutorial of Ajax techniques, patterns, and use cases. The book begins by exploring the roots of Ajax, covering how the evolution of the web and new technologies directly led to the development of Ajax techniques. A detailed discussion of how frames, JavaScript, cookies, XML, and XMLHttp requests (XHR) related to Ajax is included. After this introduction, the book moves on to cover the implementation of specific Ajax techniques. Request brokers such as hidden frames, dynamic iframes, and XHR are compared and contrasted, explaining when one method should be used over another. To make this discussion clearer, a brief overview of HTTP requests and responses is included.

Once a basic understanding of the various request types is discussed, the book moves on to provide in-depth examples of how and when to use Ajax in a web site or web application. Different data transmission formats, including plain text, HTML, XML, and JSON are discussed for their advantages and disadvantages. Also included is a discussion on web services and how they may be used to perform Ajax techniques. Next, more complex topics are covered. A chapter introducing a request management framework explores how to manage all of the requests inside of an Ajax application. Ajax debugging techniques are also discussed.

The last part of the book walks through the creation of two full-fledged Ajax web applications. The first, FooReader.NET, is an Ajax-powered RSS reader. The second, called AjaxMail, is an Ajax-enabled email system. Both of these applications incorporate many of the techniques discussed throughout the book.

Professional Ajax 2nd edition is written for Web application developers looking to enhance the usability of their web sites and web applications and intermediate JavaScript developers looking to further understand the language. Readers should have familiarity with XML, XSLT, Web Services, PHP or C#, HTML, CSS. This book is not aimed at beginners without a basic understanding of the aforementioned technologies. Also, a good understanding of JavaScript is vitally important to understanding this book. Those readers without such knowledge should instead refer to books such as Beginning JavaScript, Second Edition (Wrox, 2004, ISBN: 978-0-7645-5587-9) and Professional JavaScript for Web Developers (Wrox, 2005, ISBN: 978-0-7645-7908-0).

Professional Ajax 2nd edition adds nearly 200 pages of new and expanded coverage compared to the first edition. Some of the new topics covered here include:

• Ajax Libraries including the Yahoo! Connection Manager, Prototype, and jQuery
• Request Management with Priority Queues and the RequestManager Object
• Comet push-based web systems and HTTP streaming
• Maps and Mashups with Geocoding, Google Maps API and Yahoo! Maps API
• Ajax Debugging with FireBug and Microsoft Fiddler

  ASP.NET AJAX Extensions (formerly code-named "Atlas")

And of course the Second Edition retains and updates the core first edition content including:

• the range of request brokers (including the hidden frame technique, iframes, and XMLHttp) and explains when one should be used over another
• different Ajax techniques and patterns for executing client-server communication
• Ajax patterns including predictive fetch, page preloading, submission throttling, incremental field and form validation, periodic refresh, multi-stage download and more
• Syndication with RSS, Atom, and XParser
• JSON and creating an autosuggest textbox example
• web site widgets for a news ticker, weather information, web search, and site search
• Ajax Frameworks JSpan, DWR, and Ajax.NET Professional
• A Web-based RSS/Atom aggregator case study
• An AjaxMail case study

This book is also available as part of the 4-book JavaScript and Ajax Wrox Box (ISBN: 0470227818). This 4-book set includes:

• Professional JavaScript for Web Developers (ISBN: 0764579088)
• Professional Ajax 2nd edition (ISBN: 0470109491)
• Professional Web 2.0 Programming (ISBN: 0470087889)
• Professional Rich Internet Applications: Ajax and Beyond (ISBN: 0470082801)

This book is for anyone who wants to learn how to build rich and interactive web sites that run on the Microsoft platform. With the knowledge you gain from this book, you create a great foundation to build any type of web site, ranging from simple hobby-related web sites to sites you may be creating for commercial purposes.

Anyone new to web programming should be able to follow along because no prior background in web development is assumed. The book starts at the very beginning of web development by showing you how to obtain and install Visual Web Developer. The chapters that follow gradually introduce you to new technologies, building on top of the knowledge gained in the previous chapters.

Do you have a strong preference for Visual Basic over C# or the other way around? Or do you think both languages are equally cool? Or maybe you haven't made up your mind yet and want to learn both languages? Either way, you'll like this book because all code examples are presented in both languages!

Even if you're already familiar with previous versions of ASP.NET, with the 1.x versions in particular, you may gain a lot from this book. Although many concepts from ASP.NET 2.0 are brought forward into ASP.NET 3.5, you'll discover there's a host of new stuff to be found in this book, including an introduction to LINQ, the new CSS and JavaScript debugging tools, new ASP.NET controls, and integrated support for ASP.NET Ajax.

To build effective and attractive database-driven web sites, you need two things: a solid and fast framework to run your web pages on and a rich and extensive environment to create and program these web pages. With ASP.NET 3.5 and Visual Web Developer 2008 you get both. Together they form the platform to create dynamic and interactive web applications.

ASP.NET 3.5 builds on top of its popular predecessor ASP.NET 2.0. While maintaining backward compatibility with sites built using this older version, the Microsoft .NET Framework 3.5 in general and ASP.NET 3.5 in particular add a lot of new, compelling features to the mix.

Continuing the path of "less code" that was entered with the 2.0 version of the .NET Framework, ASP.NET 3.5 lets you accomplish more with even less code. New features like LINQ that are added to the .NET Framework allow you to access a database with little to no hand written code. The integration of Microsoft ASP.NET Ajax into the ASP.NET Framework and Visual Web Developer means you can now create fast responding and spiffy web interfaces simply by dragging a few controls onto your page and setting a few properties. This book gives you an in-depth look at both these technologies.

The support for cascading style sheets (CSS), the language to lay out and format web pages, has undergone a major overhaul in Visual Web Developer. The design time support, that shows you how a page will eventually look in the browser, has been vastly improved. Additionally, Visual Web Developer now ships with a lot of tools that make writing CSS a breeze.

However, drag-and-drop support and visual tools are not the only things you'll learn from this book. ASP.NET 3.5 and Visual Web Developer 2008 come with a great and extensive set of tools to help you program your web applications. These tools range from the new LINQ syntax that allows you to query data and databases in your web applications, to the vastly improved debugging capabilities that allow you to debug your application from client-side JavaScript all the way up into your server-side code, all with the same familiar user interface, commands, and actions.

Under the hood, ASP.NET 3.5 makes use of the same run-time as version 2.0. This ensures a great backward compatibility with that version, which means that ASP.NET 2.0 applications continue to run under the new framework. But don't be fooled by the fact that the run-time hasn't changed. Although the technical underpinnings needed to execute your web application haven't changed, the .NET 3.5 Framework and ASP.NET add a lot of new features, as you'll discover in this book.

Probably the best thing of Visual Web Developer 2008 is its price: it's available for free. Although the commercial versions of Visual Studio 2008 ship with Visual Web Developer, you can also download and install the free Express Edition. This makes Visual Web Developer 2008 and ASP.NET 3.5 probably the most attractive and compelling web development technologies available today.

This book teaches you how to create a feature-rich, data-driven, and interactive web site. Although this is quite a mouthful, you'll find that with Visual Web Developer 2008 this isn’t as hard as it seems. You'll see the entire process of building a web site, from installing Visual Web Developer 2008 in Chapter 1 all the way up to putting your web application on a live server in Chapter 18. The book is divided into 18 chapters, each dealing with a specific subject.

Chapter 1, “Getting Started With ASP.NET 3.5.” In this chapter you'll see how to obtain and install Visual Web Developer 2008. You'll get instructions for downloading and installing the free edition of Visual Web Developer 2008, called the Express Edition. You are also introduced to HTML, the language behind every web page. The chapter closes with an overview of the customization options that Visual Web Developer gives you.

Chapter 2, “Building an ASP.NET Web Site.” This chapter shows you how to create a new web site and how to add new elements like pages to it. Besides learning how to create a well-structured site, you also see how to use the numerous tools in Visual Web Developer to create HTML and ASP.NET pages.

Chapter 3, “Designing Your Web Pages.” Visual Web Developer comes with a host of tools that allow you to create well-designed and attractive web pages. In this chapter, you see how to make good use of these tools. Additionally, you learn about CSS, the language that is used to format web pages.

Chapter 4, “Working with ASP.NET Controls.” ASP.NET Server controls are one of the most important concepts in ASP.NET. They allow you to create complex and feature-rich web sites with very little code. This chapter introduces you to the large number of server controls that are available, explains what they are used for, and shows you how to use them.

Chapter 5, “Programming Your ASP.NET Web Pages.” Although the built-in CSS tools and the ASP.NET server controls can get you a long way in creating web pages, you are likely to use a programming language to enhance your pages. This chapter serves as an introduction to programming with a strong focus on programming web pages. Best of all: all the examples you see in this chapter (and the rest of the book) are in both Visual Basic and C#, so you can choose the language you like best.

Chapter 6, “Creating Consistent Looking Web Sites.” Consistency is important to give your web site an attractive and professional appeal. ASP.NET helps you create consistent-looking pages through the use of master pages, which allow you to define the global look and feel of a page. Skins and themes help you to centralize the looks of controls and other visual elements in your site. You also see how to create a base page that helps to centralize programming code that you need on all pages in your site.

Chapter 7, “Navigation.” To help your visitors find their way around your site, ASP.NET comes with a number of navigation controls. These controls are used to build the navigation structure of your site. They can be connected to your site's central site map that defines the pages in your web site. You also learn how to programmatically send users from one page to another.

Chapter 8, “User Controls.” User Controls are reusable page fragments that can be used in multiple web pages. As such, they are great for repeating content like menus, banners, and so on. In this chapter, you learn how to create and use User Controls and enhance them with some programmatic intelligence.

Chapter 9, “Validating User Input.” A large part of interactivity in your site is defined by the input of your users. This chapter shows you how to accept, validate, and process user input using ASP.NET server controls. Additionally, you see how to send e-mail from your ASP.NET web application and how to read from text files.

Chapter 10, “ASP.NET Ajax.” Microsoft ASP.NET Ajax allows you to create good looking, flicker free web pages that close the gap between traditional desktop applications and web applications. In this chapter you learn how to use the built-in Ajax features to enhance the presence of your web pages, resulting in a smoother interaction with the web site.

Chapter 11, “Introduction to Databases.” Understanding how to use databases is critical to building modern web sites, as most modern web sites require the use of a database. You'll learn the basics of SQL, the query language that allows you to access and alter data in a database. In addition, you are introduced to the database tools found in Visual Web Developer that help you create and manage your SQL Server databases.

Chapter 12, “Displaying and Updating Data.” Building on the knowledge you gained in the previous chapter, this chapter shows you how to use the ASP.NET data-bound and data source controls to create a rich interface that enables your users to interact with the data in the database that these controls target.

Chapter 13, “LINQ.” LINQ is Microsoft's new solution for accessing objects, databases, XML, and more. In this chapter you'll see how to use LINQ to SQL to access SQL Server databases. Instead of writing a lot of manual code, you create a bunch of LINQ objects that do the heavy work for you. This chapter shows you what LINQ is all about, how to use the visual LINQ designer built into Visual Web Developer, and how to write LINQ queries to get data in and out of your SQL Server database.

Chapter 14, “Presenting Data: Advanced Topics....

Ajax has swept through the IT world like wild-fire over the last 8 months. It’s being deployed by major corporations across the world to improve the user-experience of their websites (e.g. Google maps, Flickr, Google Suggest and Amazon Discuss). This is only the beginning of its potential. It seems likely that within the year Ajax techniques will become one of the corner stones of contemporary web development. No website will want to be without them and no web designer will want to pass up on these skills.

This book follows on from Apress’ extremely successful Foundations of Ajax title. It takes the reader on a detailed journey through the Ajax technology and shows them how to integrate Ajax with Microsoft’s popular .NET 2.0 Framework to produce their own implementations of the functionality they’re beginning to see on the web. The keystone of the book is practicality. We show people how to put theory into practice and bring Ajax to their web applications in a professional manner.

Crucially, for a book in such a rapidly moving field, we also look ahead to when Microsoft will unveil it’s ‘Atlas’ Ajax toolkit for Visual Studio 2005. We tell people what to expect and how they can begin preparing for it.
