Controller:

[HttpPost]
        [AllowAnonymous]
        [ValidateAntiForgeryToken]
        public ActionResult Domain(Domain domain)
        {
            try
            {
                int refID = Convert.ToInt32(Session["RefID"]);
                if (ModelState.IsValid && refID > 0)
                {
                    userType type = new userType();
                    int id = type.AddDomain(domain, refID);
                    if (id != 0)
                    {
                        ViewBag.Message = "Domain added successfully";
                    }
                }
                return View();
            }
            catch

                return View();
            }

        }

 $('#bn-success').on('click', function() {
        $.notify({
            icon: 'font-icon font-icon-check-circle',
            title: '<strong>Heads up!</strong>',
            message: @ViewBag.Message
        },{

        });
    });

Answer 1

'@ViewBag.Message'

$('#bn-success').on('click', function() {
    $.notify({
        icon: 'font-icon font-icon-check-circle',
        title: '<strong>Heads up!</strong>',
        message: '@ViewBag.Message'
    },{
        type: 'success'
    });
});
