Description:
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 Vis...
