Ajax Development with ASP.NET 2.0
Course No. ISI-1071 3 Days Instructor-led, Hands-on
Introduction
This three-day intensive course introduces a fast-track path to understanding the ASP.NET implementation of Ajax (formerly code named ATLAS) and how this technology can increase the power and functionality of your code while conserving time and effort.
Microsoft Ajax is a web-client framework that makes building asynchronous client side applications easier. It provides a prewritten framework that gives you a structured environment in which to work. Ajax for ASP .NET also provides you with an object model and standardized debugging to make development faster and simpler.
Ajax is a new way of combining a number of Web technologies including JavaScript, dynamic HTML, and a feature known as XmlHttp (which reduces the need for client browsers to constantly reconnect to the server every time new information is downloaded). But at the moment, people developing with Ajax have to write their code from the ground up, which is complex and time consuming.
The course guides you through a series of practical examples that demonstrate the Microsoft Ajax framework and available controls. After taking this course, you'll be able to compile a seamless Ajax-based application of your own!
