    We have telerik:RadMultiPage with 3 RadPageView control on a Visual Webpart in sharepoint site.

    When this webpart is opened user enters few detail and then click on next button which will take then to next RADPageView .

    But on Production server we are getting following error when user click on Next button 

    ScriptResource.axd?d=OuxNwVWHD89YhOJQ8KoflBg1KGlPeB5feLGISY35w5AR9riq5maPEdVKtJ3yHJoTRwy9UXHCxY_UZt…:5 Uncaught Sys.WebForms.PageRequestManagerParserErrorException: 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'.

    We are not having this issue in dev or Test environment , We have tried checking Firewall setting to check if Ajax header information is gettgin trimmed but it is not .

    Please let me know If there is anything we can try , or there is any known issue regrading this ?

    Hi Amit,

    Usually the experienced error means that the Response was changed during an AJAX request, which often happens when a server error is thrown and there is a redirect for that.

    You try registering the Next button changing the PageViews as a PostBack control and see whether this will help in resolving the case:
    RadScriptManager sm = (RadScriptManager)Page.Master.FindControl("scriptManager");
    sm.RegisterPostBackControl(this.btnNext);

    Thank you Vessy  , 

    Looks like we cannot update Server patch in production with above CU  because of DB huge DB size, I will try the approach which you have mentioned above and will let you know if it worked !!
