Return Code 0, Json, Custom Designer

  • Return Code 0, Json, Custom Designer
  • Hi guys,
    I just create a Designer for my Custom Widget and went i try to Edit the content my Widget show this Error : Return Code 0

    And i have this in my Log :

    Type : System.Web.HttpException, System.Web, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
    Message : Server cannot set status after HTTP headers have been sent.

    My issues is because i use this code in my Controller for trimming my Json result. Because i d'ont want he return me a partial View();
    My Code :

            protected override void OnActionExecuting(ActionExecutingContext filterContext)
                if (Request.IsAjaxRequest())


            protected override void OnResultExecuted(ResultExecutedContext filterContext)
                if (Request.IsAjaxRequest())


    So if you have the same problem d'ont use : if (Request.IsAjaxRequest()).

    Use a Boolean for just executing the action on the good request because now the code was executed on every Ajax Request.

    I Hope this help.
