copied!<p>I would suggest you a custom model binder:</p> <pre><code>using System; using System.Globalization; using System.Web.Mvc; public class MyClassBinder : DefaultModelBinder { protected override object CreateModel(ControllerContext controllerContext, ModelBindingContext bindingContext, Type modelType) { var model = (MyClass)base.CreateModel(controllerContext, bindingContext, modelType); var day = bindingContext.ValueProvider["MyDate-Day"]; var month = bindingContext.ValueProvider["MyDate-Month"]; var year = bindingContext.ValueProvider["MyDate-Year"]; var dateStr = string.Format("{0}/{1}/{2}", month.AttemptedValue, day.AttemptedValue, year.AttemptedValue); DateTime date; if (DateTime.TryParseExact(dateStr, "MM/dd/yyyy", null, DateTimeStyles.None, out date)) { model.MyDate = date; } else { bindingContext.ModelState.AddModelError("MyDate", "MyDate has invalid format"); } bindingContext.ModelState.SetModelValue("MyDate-Day", day); bindingContext.ModelState.SetModelValue("MyDate-Month", month); bindingContext.ModelState.SetModelValue("MyDate-Year", year); return model; } } </code></pre> <p>This simplifies your controller action to:</p> <pre><code>[AcceptVerbs(HttpVerbs.Post)] public ActionResult MyAction(MyClass myClass) { if (!ModelState.IsValid) { return View(myClass); } // Do something with myClass return RedirectToAction("success"); } </code></pre> <p>And register the binder in Global.asax:</p> <pre><code>protected void Application_Start() { RegisterRoutes(RouteTable.Routes); ModelBinders.Binders.Add(typeof(MyClass), new MyClassBinder()); } </code></pre>
