ASP.NET AJAX Using Visual Basic

This three-day course provides a practical introduction to developing rich Internet applications using ASP.NET AJAX and Visual Basic. Because of the rich support provided by Microsoft’s AJAX tools, an ASP.NET programmer can get up and running in this new environment quickly. This course shows the way. It is current to ASP.NET 4.0 and Visual Studio 2010. The course includes an introduction to the popular JavaScript library jQuery, which is now bundled with ASP.NET AJAX.

The course begins with a discussion of rich Internet applications, which include substantial client-side code, typically JavaScript. Microsoft’s AJAX tools are surveyed, and a simple AJAX application is illustrated. The JavaScript programming language is covered in enough detail to give the student a good working knowledge of writing client scripts. To retrieve and update information on a Web page from client-side code, the programmer needs to use DHTML or the Document Object Model (DOM), which are discussed in the third chapter along with Cascading Style Sheets (CSS) and an introduction to jQuery.

Chapter 4 covers the AJAX Client Library, which simplifies client-side programming with JavaScript extensions, a debugging trace facility, and various API shortcuts. The next chapter covers partial page rendering, which enables part of a page to be updated asynchronously, resulting in an improved user experience. The next chapter covers various techniques for making remote-method calls, resulting in greater efficiency in an AJAX application. The next chapter introduces the AJAX Control Toolkit, which provides many very useful controls enabling sophisticated client-side effects with relatively little programming. The last chapter covers built-in application services, which provides a client-side API to various services on the server, such as authentication and user profiles.

Numerous programming examples and exercises are provided. A case study illustrates a number of features of ASP.NET AJAX working together. The student will receive a complete set of notes and all the programming examples.

• A good working knowledge of Web application development using ASP.NET, Visual Studio and Visual Basic. The student should have a basic knowledge of HTML. Exposure to JavaScript would be helpful but not required. A basic knowledge of ADO.NET would be helpful for understanding the case study and some of the examples.

On completion of this course, the student should be able to

• Gain a thorough understanding of the philosophy and implementation of rich Internet applications
• Create interactive Web pages using DHTML, JavaScript, Cascading Style Sheets and jQuery
• Explain the benefits of AJAX in creating non-blocking and interactive Web applications
• Use ASP.NET AJAX and Visual Studio to easily implement AJAX applications
• Create visually rich and attractive Web applications with controls in the AJAX Control Toolkit
