Without this even if there is no error in the web service, your extender control will not work. Also you need to specify the path of the webservice as the path from the root like this. ServicePath="~/Service/MyAutoCompleteService.asmx" Hope this will help you. Thanks Regards, Raja, USA Poster, if this helps please login to Mark As Answer. \| Alert Moderator

Ensure that the attribute of your web service class is following


[WebService(Namespace = "http://tempuri.org/")]

    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

    [System.Web.Script.Services.ScriptService]

    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 

    // [System.Web.Script.Services.ScriptService]

    public class AutoCompleteService : System.Web.Services.WebService

    {



   }

Notice [System.Web.Script.Services.ScriptService]. Without this even if there is no error in the web service, your extender control will not work.

Also you need to specify the path of the webservice as the path from the root like this.

ServicePath="~/Service/MyAutoCompleteService.asmx"

Hope this will help you.
