Hi,

I am trying to implement Auto Complete feature in my website.

I have added the AutoCompleteExtender in my web page and I have also assigned a TargetControlID.

When I start typing in letter, it attempts to call the web service, but for some reason I get an error “Not authorized”. I catch that error in Global.ascx (Application_Error).

I am using Windows Authentication for the website.

I am using .NET Framework 2.0 with Visual Studio 2008.

Here is what my web service looks like:

/// <summary>
    /// Summary description for WebService2
    /// </summary>
    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [ToolboxItem(false)]
    [System.Web.Script.Services.ScriptService]
    public class WebService2 : System.Web.Services.WebService
    {

        [WebMethod]
        public string HelloWorld()
        {
            return "Hello World";
        }

        [WebMethod]
        [System.Web.Script.Services.ScriptMethod]
        public string[] GetCompletionList(string prefixText, int count)
        {
            if (count == 0)
            {
                count = 10;
            }

            if (prefixText.Equals("xyz"))
            {
                return new string[0];
            }

            Random random = new Random();
            string[] items = new string[20];

            for (int i = 0; i < count; i++)
            {
                char c1 = (char)random.Next(65, 90);
                char c2 = (char)random.Next(97, 122);
                char c3 = (char)random.Next(97, 122);

                items[i] = prefixText + c1 + c2 + c3;

                //items.Add(prefixText + c1 + c2 + c3);
            }
            return items;
        }
    }

Any help would be appreciated.

Thanks.

btw i m not able to find constructor of the class ? , this might be causing error

Thanks for that.

I have managed to fix the problem.

I have added different rules so that users can access only a few pages and apparently I had not set any rule for my webserivce hence it was failing.

Thanks
