Method Error 12030
using CascadingDropDowns linked to a databse as described on http://www.asp.net/AJAX/AjaxControlToolkit/Samples/Walkthrough/CCDWithDB.aspx Unfortunatly, the code contains a little bug, resulting a Method error 12030 or Method error 12031 being displayed in the dropdownlist, instead of the expected data. Because the webservice is being called from (java)script, using ASP.NET AJAX, the enclosing class has to be decorated with the System.Web.Script.Services.ScriptService attibute to make it work. C#: [System.Web.Script.Services.ScriptService()] public class MyWebserviceClass : System.Web.Services.WebService { [WebMethod] public function MyWebServiceFunction() { // function body } } VB: Public Class MyWebserviceClass Inherits System.Web.Services.WebService Public Function MyWebServiceFunction() ' function body End Function End Class Too bad Microsoft forgot to mention this in the example! Method error 12002 And when we're at it: Method error 12002 indicates a timeout error, not uncommon when debugging. Method Error 500 This may also occur from time to time. It's the server telling you there's been an Internal Server Error with code 500. You may want to debug the web service you're using when you see this error.

the values to CascadingDropDownNameValue and returning the values array. The first time I run it I get a method error 500 in the parent drop down and a method error 12030 in the child.
