命名空间 'AjaxControlToolkit' 中不存在类型或命名空间名称 'HtmlEditorExtender'

Question

 <form id="form1" runat="server">   
     <div>
    <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager><ajaxToolkit:ToolkitScriptManagerID="ToolkitScriptManager1"runat="server">
</ajaxToolkit:ToolkitScriptManager>
    <asp:TextBox ID="TxtEditor" runat="server"/>
        <ajaxToolkit:HtmlEditorExtender ID="HtmlEditorExtender1" runat="server" TargetControlID="TxtEditor">                
        </ajaxToolkit:HtmlEditorExtender>
    <br/>
    <asp:Button runat="server" Text="Submit" OnClick="Submit"/>

</form>

This is the design page and I add "<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>" at the top of the page

protected global::AjaxControlToolkit.HtmlEditorExtender HtmlEditorExtender1;

I am getting error on this line.

您使用 "asp" 标签前缀注册 "AjaxControlToolkit" 命名空间，但使用 "ajaxToolkit" 前缀访问 HtmlEditorExtender。到处都改成"ajaxToolkit"。

命名空间 'AjaxControlToolkit' 中不存在类型或命名空间名称 'HtmlEditorExtender'

The type or namespace name 'HtmlEditorExtender' does not exist in the namespace 'AjaxControlToolkit'
