Description: This introduction to ASP.NET AJAX will include:
- Introduction to ASP.NET AJAX Controls.
- Introduction to the attributes used for Web Services.
- Calling a web service in JavaScript.
- Quick Intro to the UpdatePanel.
- Error Handling. By default, errors are generated as JavaScript
alerts, we’ll look at the options for handling errors so that user’s
aren’t forced into the annoying JavaScript alert popup.
- The data format that the UpdatePanel uses. When does AJAX not
use XML or JSON for data transfer? When using the UpdatePanel. We’ll
look at the Update Panel’s data transfer format.
- History. One of the most frustrating things from a user’s
standpoint is that hitting back on Ajax application takes them out of
the application. We’ll look at what a developer must do so that a user
hitting back does not exit from the application, but merely goes back
to the previous state of the application.
