The control with ID 'ace' requires a ScriptManager on the page

Posted on 16th Feb 2014 07:03 pm by admin

I'm trying to add a simple AlwaysVisibleControlExtender to my page, but it's not working. I get the following error:The control with ID 'ace' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.
Here is my code:<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" Title="Untitled Page" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %> <%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" Title="Untitled Page" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
I'm pretty sure it's setup correctly. I think it's a config issue. I'm using VS 2008, but this site was originally created in VS2005 then converted.
