We've posted a book excerpt article on Wrox.com that should be of interest to the Ajax professionals in this forum. The article is:
Developing Ajax-Enabled Controls and Components: Periodic Refresh Pattern, by Dr. Shahram Khosravi, from his recent book
Professional ASP.NET 2.0 Server Control and Component Development. Here's the beginning of the article:
Quote:
quote:Ajax-enabled components that use the Periodic Refresh pattern periodically poll the server for changes. This article develops an Ajax-enabled custom control named AjaxNotifier that will show you how to use the Periodic Refresh pattern to develop your own Ajax-enabled controls.
AjaxNotifier is an Ajax-enabled control that periodically polls the server for the latest posted notification and displays the notification in a pop-up dialog, shown in Figure 1. As this figure shows, the pop-up dialog exposes two pieces of information about a notification: the source of the notification (notifier) and the content of the notification.

We hope you enjoy the
complete article.
