A Chat with ASP.NET and Ajax

Ajax.NET - A free library for the Microsoft .NET Framework
Asynchronous JavaScript and XML (AJAX) has recently become the
craze thanks, in no small part, to Google's usage of it in
Google Suggest as well as Google Maps. In ASP.Net terms, AJAX
allows server-side processing to occur without requiring
postback, thus enabling clients (browsers) with rich
server-side capabilities. In other words it provides a
framework for asynchronously dispatching and processing
requests and responses from the server. AJAX leverages a number
of existing technologies, which aren't particularly new,
however fondness for what these technologies have to offer
(collectively, they are AJAX) has recently soared. Enter
Michael Schwarz's AJAX .Net wrapper which allows ASP.Net
developers to quickly and easily deploy pages capable of easily
capitalizing on AJAX. Users should be cautioned that the
wrapper is early in development, and as such isn't fully
matured.

Changing UpdatePanel's ContentTemplate dynamically
An UpdatePanel is an ASP.NET Ajax control to update a defined area of a ASP.NET page, while the other parts of the page remain unchanged. This has two main advantages: Less amount of data is transferred over the network during the update of the page and the usability of the application increases because the user can focus the changes of the updated part of the webpage easily. An example for that behaviour is a login dialog which displays success or failure after a user's login by changing the text of a Label. This article goes one step further: I will explain how one can change the whole content of an UpdatePanel programmatically. A use-case for that could be to display information with different controls, to give the user various views to it. To keep it simple, the example in this article displays a list of items in 2 kind of views for the user: In a BulletedList and in a ListBox.
