    Hi !!!

    I have a problem regarding the autocomplete extender in ASP.NET - it works fine in all pages I have, but NOT in a master page and i don't know why.

    In other words, when the web page is integrated into a master page, the autocomplete control does not work anymore.

    Hi Raul Soni

      According to your description,I have made a sample here.I create a Webservice file to save the ServiceMethod of AutoCompleteExtender.I find it works well in a web page which is integrated into a master page.If you still have problems,could you please post the detail codes about how you use the autocompleteextender in the master page and child page?

    More details about my test demo, you could refer to below codes:

    aspx integrated into a master page:

    <%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="autoextend.aspx.cs" Inherits="Dact._12._17.autoextend" %>
    <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>
    <asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
                <ajaxToolkit:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" TargetControlID="TextBox1" ServicePath="WebService1.asmx" ServiceMethod="GetData" MinimumPrefixLength="1"  ></ajaxToolkit:AutoCompleteExtender>


    [WebService(Namespace = "http://tempuri.org/")]
        [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[] GetData(string prefixText, int count)
                string[] data = new string[10000];
                for (int i = 0; i < data.Length; i++)
                    data[i] = i.ToString("0000");
                return data.Where(p => p.IndexOf(prefixText) >= 0).Take(count).ToArray();

    Hi Raul Soni,

    Have you added EnablePageMethods="true" property to your script manager? If not add.
