title: AutoCompleteextender Does not call service
body: <p>I have looked at multiple examples of fixing this issue, but none of the resolutions i found seemed to work. I even created a simple page to call my service. I have tested the service in the browser directly, it returns data fine. I have placed break point in service to see if it called and they never seem to be hit there. Here is my simple web page:</p>
  
  <pre><code>&lt;%@ Page Language="vb" AutoEventWireup="false" CodeBehind="demo.aspx.vb" Inherits="RasDelegates.demo" %&gt;
  &lt;%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %&gt;
  &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
  &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
  &lt;head runat="server"&gt;
      &lt;title&gt;&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;form id="form1" runat="server"&gt;
      &lt;div&gt;
  
      &lt;/div&gt;
      &lt;asp:ScriptManager ID="ScriptManager1" runat="server"&gt;
      &lt;/asp:ScriptManager&gt;
      &lt;br /&gt;
      &lt;br /&gt;
      &lt;br /&gt;
      &lt;asp:TextBox ID="TextBox1" runat="server" AutoComplete="Off"&gt;&lt;/asp:TextBox&gt;
      &lt;asp:AutoCompleteExtender ID="TextBox1_AutoCompleteExtender" runat="server" 
          DelimiterCharacters="" 
          MinimumPrefixLength="2" 
          CompletionSetCount="15" 
          CompletionInterval="10"
          Enabled="True" 
          ServicePath="../WebServices/EmpWS.asmx" 
          TargetControlID="TextBox1" 
          ServiceMethod="FindEmployee"&gt;&lt;/asp:AutoCompleteExtender&gt;
  
      &lt;/form&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>And my simple WebService</p>
  
  <pre><code>Imports System.Web
  Imports System.Web.Services
  Imports System.Web.Services.Protocols
  Imports System.ComponentModel
  Imports System.Collections.Generic
  Imports System.Web.Script.Serialization
  Imports System.String
  
      &lt;WebService(Namespace:="http://ws_EA01")&gt; _
      &lt;WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)&gt; _
      &lt;Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()&gt; _
      &lt;System.Web.Script.Services.ScriptService()&gt; _    
  Public Class EmpWS
      Inherits System.Web.Services.WebService
      &lt;WebMethod()&gt; _
      Public Function FindEmployee(ByVal prefixText As String) As List(Of String)
          Dim json As New System.Web.Script.Serialization.JavaScriptSerializer
          Dim list As List(Of String)
          list = WebServices.clsWebService.GetEmps(prefixText)
  
          Dim str As String = Nothing
          Try
              str = json.Serialize(list)
          Catch ex As Exception
  
          End Try
  
          Return list.ToArray().ToList
      End Function
  
  End Class
  </code></pre>
  
  <p>Any Idea What I seme to be missing?</p>
