I couldn't get Ajax working on this one particular ASP.Net website and after a lengthy search I found the fix here  http://geekswithblogs.net/influent1/archive/2007/05/16/112544.aspx .  I had to add this to the web.config: < system.web > < pages > < controls > < add tagPrefix = " asp " namespace = " System.Web.UI " assembly = " System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35 " / > < add tagPrefix = " asp " namespace = " System.Web.UI.WebControls " assembly = " System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35 " / > < / controls > < / pages > < / system.web >

In the Datasets area right-click on a DataSource and select Add . Enter in the Name of the new field and the Database field or Calculated field . Then we need to update the tie between the Dataset and SQL Server by clicking on the Data tab and selecting our Dataset in the dropdown and updating the query.
