Introducing the UpdatePanel Control
When an ASP.NET page performs a postback to the server, there is often a pause followed by a flash of the browser screen as content returned from the server is rendered.

What You Need to Get the Most from This Short Cut
To run an ASP.NET Ajax web site, you need:
A web server running IIS 5 or later (for local development, the Visual Studio 2005 Web Server can be used instead)
ASP.NET 2.0, which can be downloaded from http://msdn.microsoft.com/netframework/downloads/updates/default.aspx
ASP.NET Ajax, which can be downloaded from http://ajax.asp.net/default.aspx?tabid=47&subtabid=471
Any text editor can help you develop an ASP.NET Ajax site, but we recommend you download and install the free Visual Web Developer 2005 IDE, available at http://msdn.microsoft.com/vstudio/express/vwd/download/.

We use the SQL Server sample database, AdventureWorks, for which download and installation instructions can be found at http://msdn2.microsoft.com/en-us/library/ms310325.aspx.
On the client side, IE6 or later, Firefox 1.5 or later, Opera 9 or later ...
