I have seen in many forums people asking questions as “how to populate the cascadingdropdown with values from database". Although there was a sample provided for the same in the ASP.NET AJAX ControlToolkit, most of the learners (novice) following the walkthrough given at http://ajax.asp.net/ajaxtoolkit/Walkthrough/CCDWithDB.aspx get struck at the CarsTableAdapters used in the webservice.

So, I have posted an article Creating a CascadingDropDown Using AJAX at aspalliance.com which explains the step-by-step procedure on how to create CascadingDropDown using database values with the help of Microsoft SQL Server 2005 Express Edition.
