Hi everyone
i'm new to web services in well basically in my Solution ,it has 3 basic projects namely (PAL(all the web form interfaces are there) , BAL(refer business logic) and DAL ( refer data access -SQL server part). PAL is linked to BAL and BAL is LINKED to DAL. then i want to add a Ajax auto complete extender to a Textbox in a web form located at PAL .just say testwebform.aspx and i write a webService in a BAL namely webService1 and add a webmethod as follows..

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Data;
using System.Data.Sql;
using AjaxControlToolkit;
using DAL;

namespace BAL
    /// <summary>
    /// Summary description for WebService1
    /// </summary>
    [WebService(Namespace = "http://testserver/webservices")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 

    public class WebService1 : System.Web.Services.WebService

        public String[] GetCompanyList(String prefixText, Int32 count)
            String[] strList = null;
            List<string> strCompanyList = new List<string>();

            String Consigneeprefix = prefixText + "%";
            String Sql = "SELECT TOP'"+count+"'[conCode],[conName] FROM [tblConsignee] WHERE [cusCode] ='"+webSupport.ShipperCode().Trim() +"' AND  [conName] LIKE'" + Consigneeprefix +"'";

// webSupport.ShipperCode refer to get the ShipperCode for Sql Query String via.

            DataTable dt = new DataTable();
            dt = SQLTrans.executeQuery(Sql, "tbl");

            if (dt.Rows.Count> 0)
                for ( int i = 0 ; i< dt.Rows.Count;i++)
                  // Here is the Douted area in web method.

                  CreateAutoCompleteItem(dt.Rows[i][0].ToString(), Convert.ToString(dt.Rows[i][1].ToString())));


                strList = new String[10];
                strList = strCompanyList.ToArray();

                //No records found

            return strList;

then i called the web service method from PAL's particular webform by using following AJAX auto completeextender as follows. and it says "Server tag is Not well formed". i refer Using AJAX AutoCompleteExtender for autosuggest[^] to get the idea of webServices and AJAX auto Complete extender.But i also dnt know how to Link return SQL query's return two Fields([conCode],[conName]) values. it is conCode to a value flied of the Extender and conNameto Text feild in the Ajax extender.

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

<asp:TextBox ID="TextBox1" runat="server" Height="19px" Width="256px"></asp:TextBox>
            <asp:AutoCompleteExtender ID="txtAutoCompleteforCompany_AutoCompleteExtender"
	            MinimumPrefixLength="1" TargetControlID="TextBox1" 
	            runat="server" OnClientItemSelected="setCompanyMasterID" 


If Someone Could help me on this matter it could be a great help for me.
Thanks in Advance!!!

How come your web service is in BAL?? shouldn't it be in PAL i.e. where you web pages are i.e. your ASP.NET application.

Found it! you haven't got a space between these two attributes:


Change the above to:

CompletionSetCount="10" CompletionInterval="100"

See if this works.
