I'm unable to access my RadEditor using client-side Javascript functions when I use a Master Page. The identical code works fine when it's not set in a Master Page. (This is a super-simple example, lifted straight from Telerik's demos.)
The code for the page is here:
<%@ Page Title="" Language="C#" MasterPageFile="~/AltMasterPage.master" AutoEventWireup="true" CodeFile="Test2.aspx.cs" Inherits="Documentation_Test2" %>
<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
<asp:Content ID="Content1" ContentPlaceHolderID="SecondLevelHeadContent" Runat="Server">
<script type="text/javascript">
function SetHtml() {
var newValue = $get('textHtml').value;
$find("RadEditor1").set_html(newValue);
}
</script>
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="SecondLevelBodyContent" Runat="Server">
<telerik:RadScriptManager ID="ScriptManager1" runat="server" />
<telerik:RadEditor ID="RadEditor1" runat="server" />
<div class="module">
<input type="button" value="Set New Html to the RadEditor" onclick="SetHtml()"/>
<input type="text" value="New HTML" id="textHtml" />
</div>
</asp:Content>
And for the Master Page is here:
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="AltMasterPage.master.cs" Inherits="MasterPage" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<asp:ContentPlaceHolder id="SecondLevelHeadContent" runat="server" />
</head>
<body>
<form id="form1" runat="server">
<asp:ContentPlaceHolder id="SecondLevelBodyContent" runat="server" />
</form>
</body>
</html>
The Javascript error thrown is:

</head>
<body>
<form id="form1" runat="server">
<asp:ContentPlaceHolder id="SecondLevelBodyContent" runat="server" />
</form>
</body>
</html>
The Javascript error thrown is:
$find("RadEditor1") is null
The exact same code works like a champ if it's in an ASPX file that doesn't reference a Master Page. What's going on?
Thanks,
Jesse

Hi Jesse
Because of the naming container, you have to use ClientID to get the real id of that control. In your case, you have to use
$find("<%=RadEditor1.ClientID%>").set_html(newValue);
