whith the ID = "editor" or clientID = "ctl00_ContentPlaceHolder1_editor"

TagPrefix="HTMLEditor" %>
<div>
<ajaxToolkit:ToolkitScriptManager runat="Server" EnablePartialRendering="true" ID="ScriptManager1"
EnableScriptGlobalization="true" />
<asp:Panel runat="server" ID="PanelAllEditor">
<asp:Panel ID="PanelEditor" runat="server">
<asp:UpdatePanel ID="UpdatePanelEditor" runat="server">
<ContentTemplate>
<HTMLEditor:Editor runat="server" ID="editor" Width="100%" Height="500px"
ActiveMode="Design" AutoFocus="true" InitialCleanUp="true" IgnoreTab="true" CssClass="myStyle" />
</ContentTemplate>
