For those of you interested in the new features available in Visual Studio 2008 and ASP.NET 3.5 you might find the latest article on Scott Guthrie’s blog useful. As ever it’s excellent quality and comes straight from the horse’s mouth.

The article concerns the new ASP.NET Control Extenders derived from the System.Web.UI.ExtenderControl base class. These extenders allow you to add additional functionality, most usually AJAX of JavaScript user interface enhancements, to existing controls that you’ve already declared on your ASP.NET page. They provide a very neat method of keeping your UI code separate from your business logic. Scott provides a fully worked example of just the right length to make excellent lunch-break reading.
