How to get render HTML from a View by passing Model as parameter in ASP.NET MVC

        
        protected string RenderViewToString(string viewPath, T model)
        {
            using (var writer = new StringWriter())
            {
                var view = new WebFormView(viewPath);
                var vdd = new ViewDataDictionary(model);
                var viewCxt = new ViewContext(ControllerContext, view, vdd, new TempDataDictionary(), writer);
                viewCxt.View.Render(viewCxt, writer);
                return writer.ToString();
            }
        }

        Ex : EmployeeViewModel model = GetEmployeeModel(21);
             string htmlString = RenderViewToString("~/Views/EmployeeView.ascx", model);
