Hi lcp,
Can you create a new website and a new page to test the following code
<%@ Page Language="C#" %>
<%@ Register TagPrefix="CE" Namespace="CuteEditor" Assembly="CuteEditor" %>
<!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">
<title>Test Cute Editor in AJAX tab container</title>
</head>
<body>
<form id="form1" runat="server">
<CE:Editor ID="Editor1" runat="server">
</CE:Editor>
</form>
</body>
</html>
Keep my posted
Ken
