Yes there is: it’s called view models. View models are classes which are specifically tailored to the specific needs of a given view. So instead of: public ActionResult Index([Bind(Exclude = “Id”)] SomeDomainModel model) use: public ActionResult Index(SomeViewModel viewModel) where the view model contains only the properties which need to be bound. Then you could map … Read more
It turns out the reason is that ValueProviderDictionary only looks in Request.Form, RouteData and Request.QueryString to populate the value provider dictionary in the model binding context. So there’s no way for a custom model binder to allow posted files to participate in model binding without inspecting the files collection in the request context directly. This … Read more
I have found that while my domain model gets me 85% of the way to having the fields I want, it has never covered 100% of the values I want on my view. Especially when it comes to permissions and whether or not a user should have access to certain portions of the view. The … Read more
Cleanest way is to implement your own model binder public class DecimalModelBinder : DefaultModelBinder { public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { var valueProviderResult = bindingContext.ValueProvider.GetValue(bindingContext.ModelName); return valueProviderResult == null ? base.BindModel(controllerContext, bindingContext) : Convert.ToDecimal(valueProviderResult.AttemptedValue); // of course replace with your custom conversion logic } } And register it inside Application_Start(): ModelBinders.Binders.Add(typeof(decimal), new DecimalModelBinder()); … Read more
override the BindProperty from the DefaultModelBinder: public class CustomModelBinder:DefaultModelBinder { protected override void BindProperty( ControllerContext controllerContext, ModelBindingContext bindingContext, System.ComponentModel.PropertyDescriptor propertyDescriptor ) { if (propertyDescriptor.PropertyType == typeof(Range)) { base.BindProperty(controllerContext, bindingContext, propertyDescriptor); } // bind the other properties here } }
I’ve finally found an answer. Basically I don’t need the MediaTypeFormatter stuff, that’s not designed to be used in MVC environment, but in ASP.NET Web APIs, that’s why I do not see those references and namespaces (by the way, those are included in the Microsoft.AspNet.WeApi NuGet package). The solution is to use a custom value … Read more
I have this working, you have to remember to add a common indexing hidden input as explained in your referenced article: The hidden input with name = Items.Index is the key part <input type=”hidden” name=”Items.Index” value=”0″ /> <input type=”text” name=”Items[0].Name” value=”someValue1″ /> <input type=”hidden” name=”Items.Index” value=”1″ /> <input type=”text” name=”Items[1].Name” value=”someValue2″ /> <input type=”hidden” name=”Items.Index” … Read more
you can change the default model binder to use the user culture using IModelBinder public class DateTimeBinder : IModelBinder { public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName); bindingContext.ModelState.SetModelValue(bindingContext.ModelName, value); return value.ConvertTo(typeof(DateTime), CultureInfo.CurrentCulture); } } public class NullableDateTimeBinder : IModelBinder { public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName); … Read more
