    I am seeing an odd problem with RajAjaxManager.  When I load my page clean, the page works fine.  However, when I reload the page in the same session, then IsAjaxRequest is not working.  It is not set to true.  

    Below is what I am getting:

    Message: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
    Details: Error parsing near '
    <!DOCTYPE html PUB'.
    Line: 5
    Char: 84093
    Code: 0
    URI: http://sitename/jscript/MicrosoftAjax.js

    Hello Andy Macourek,

    Could you pleas verify is you have RadScriptManager on the very top of the page before the RadAjax declaration. Also please let me know whether the problem persists if you are using regular asp ScriptManager instead of RadScriptManager?
    Also please note that this is a generic ASP.NET AJAX framework error and you can take a look at the following blog post that elaborates on the matter.
