I'm currently using version 2009.1.527.35 of the Telerik RadControls for ASP.NET Ajax.  When I use the Default Content Filters ( or none) and the user edits the content using the HTML view and adds an   then clicks Design and back to HTML, the entity is translated to a space.  I narrowed down the issue to the the ConvertToXhtml content filter by a process of elimination.

Is this expected behavior?  I did notice that Firefox doesn't exhibit the same behavior--only IE 8.  I didn't try IE7 or Chrome.

I don't really care for the result--I'd like to keep XHTML formatting, but I don't really have a choice since the   is more critical to the CMS.

Here's how to reproduce the issue:

1)  Create a page with the following markup:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="WebpPrototype._Default" %>
  
<%@ 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">
  
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <div>
    <telerik:RadEditor ID="RadEditor1" runat="server" Skin="Black" ContentFilters="ConvertToXhtml,RemoveScripts,FixUlBoldItalic,IECleanAnchors,FixEnclosingP,MozEmStrong,ConvertFontToSpan,IndentHTMLContent,OptimizeSpans">
    </telerik:RadEditor>
    </div>
      
    </form>
</body>
</html>

2)  View the page in the browser.  Click HTML.  Add an &nbsp; to the content.  Click design.  Click back and the &NBSP; has been replaced with spaces.
3)  In the page markup, remove the ConvertToXhtml form the ContentFilters.  Repeat and see the expected results.

Hello Scott,

This problem is fixed in the latest Q2 2010 SP1 version 2010.2.826 of RadControls for ASP.NET AJAX. My suggestion is to test the live demos of RadEditor, which use the latest Telerik.Web.UI version. If the problem does not exist, upgrade the Telerik.Web.UI.dll in your projects bin folder with the latest one.

Best regards,
