    Firstly Use the AjaxToolkitManger.

    <ajaxToolkit:ToolkitScriptManager ID="ajt1" runat="server">

    It is prefered to use AjaxToolScriptManager if you are using Ajax Controls.
    Secondly, use proper TagPrefix:

    <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="TryOuts.Default1" %>
    <%@ Register tagPrefix="ajaxToolkit" assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" %>

    Then use ajaxToolKit instead of asp as prefix for ajax controls:

    <ajaxToolkit:AutoCompleteExtender ID="ac1" runat="server" ></ajaxToolkit:AutoCompleteExtender>

    Add the Register and use proper tagPrefix.
    Best Regards!

    If i use <ajaxToolkit:ToolkitScriptManager ID="ajt1" runat="server"> </ajaxToolkit:ToolkitScriptManager>

    It showes an error like this while accessing gridview "Only one instance of a ScriptManager can be added to the page." in this code

     With gvReceiptDetail
                    .DataSource =Receipt.OrderById
                    .DataKeyNames = Keys
                    .Visible = True
                End With

    Yes, that's right. Either use AjaxToolKitManager or ScriptManager don't use both. We can only use one script Manage in a ASP page. Since you have used Ajax controls so I suggested you to use AjaxToolKitManager.
