custom-model-binder

My team needs to develop a framework for our company and products using this framework. One of the requisites is that a product could be customized for a specific client, yet it should be easily updated with another version of the same product (not automatically). We're using ASP.NET MVC 4 + Web API (for now, a desktop product will be created next year, based on our framework), NHibernate, heavily IoC using Autofac as DI container and N-Layers. So, in some points of the WebApp, we're using ViewModels as Interfaces with one default implementation and using Autofac to link them, and that's is

In my project I want to allow users input double values in 2 formats: with using ',' or '.' as delimiter (I'm not interested in exponential form). By default value with delimiter '.' don't work. I want this behavior works for all double properties in complex model objects (currently I work with collections of objects, that contains identifiers and values). What i should use: Value Providers or Model Binders? Please, show code example of solving my problem. You could use a custom model binder: public class DoubleModelBinder : DefaultModelBinder { public override object BindModel

I have a simple model for my asp.net core controller: [HttpPost] public async Task<DefaultResponse> AddCourse([FromBody]CourseDto dto) { var response = await _courseService.AddCourse(dto); return response; } My model is : public class CourseDto { public int Id { get; set; } public string Name { get; set; } public string Genre { get; set; } public string Duration { get; set; } public string Level { get; set; } public string AgeRange { get; set; } public string Notes { get; set; } public bool Active { get; set; } public string OrganisationCode { get; set; } } I'm trying to set value of

I need to implement a functionality to allow users to enter price in any form, i.e. to allow 10 USD, 10$, $10,... as input. I would like to solve this by implementing a custom model binder for Price class. class Price { decimal Value; int ID; } The form contains an array or Prices as keys keys: "Prices[0].Value" "Prices[0].ID" "Prices[1].Value" "Prices[1].ID" ... The ViewModel contains a Prices property: public List<Price> Prices { get; set; } The default model binder works nicely as long as the user enters a decimal-convertible string into the Value input. I would like to allow inputs like

I'm using NInject with NInject.Web.Mvc. To start with, I've created a simple test project in which I want an instance of IPostRepository to be shared between a controller and a custom model binder during the same web request. In my real project, I need this because I'm getting IEntityChangeTracker problems where I effectively have two repositories accessing the same object graph. So to keep my test project simple, I'm just trying to share a dummy repository. The problem I'm having is that it works on the first request and that's it. The relevant code is below. NInjectModule: public class

Getting the error here: ValueProviderResult value = bindingContext.ValueProvider.GetValue("ConfirmationMessage"); How do I allow on a selection of values only? i.e. [ValidateInput(false)] public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { ValueProviderResult value = bindingContext.ValueProvider.GetValue("ConfirmationMessage"); ValueProviderResult value2 = bindingContext.ValueProvider.GetValue("ConfirmationMessage2"); } You have a few options. On the model add this attribute to each property that you need to allow HTML - best choice using System

I have the following controller action: [HttpPost] public ViewResult DoSomething(MyModel model) { // do something return View(); } Where MyModel looks like this: public class MyModel { public string PropertyA {get; set;} public IList<int> PropertyB {get; set;} } So DefaultModelBinder should bind this without a problem. The only thing is that I want to use special/custom binder for binding PropertyB and I also want to reuse this binder. So I thought that solution would be to put a ModelBinder attribute before the PropertyB which of course doesn't work (ModelBinder attribute is not allowed on a
