阅读更多关于 ASP.NET MVC 5 Model-Binding Edit View

I cannot come up with a solution to a problem that's best described verbally and with a little code. I am using VS 2013, MVC 5, and EF6 code-first; I am also using the MvcControllerWithContext scaffold, which generates a controller and views that support CRUD operations. Simply, I have a simple model that contains a CreatedDate value: public class WarrantyModel { [Key] public int Id { get; set; } public string Description { get; set; } DateTime CreatedDate { get; set; } DateTime LastModifiedDate { get; set; } } The included MVC scaffold uses the same model for its index, create, delete,

How to override the ASP.NET MVC 3 default model binder to resolve dependencies (using ninject) during model creation?

阅读更多关于 How to override the ASP.NET MVC 3 default model binder to resolve dependencies (using ninject) during model creation?

I have an ASP.NET MVC 3 application that uses Ninject to resolve dependencies. All I've had to do so far is make the Global file inherit from NinjectHttpApplication and then override the CreateKernel method to map my dependency bindings. After that I am able to include interface dependencies in my MVC controller constructors and ninject is able to resolve them. All that is great. Now I would like to resolve dependencies in the model binder as well when it is creating an instance of my model, but I do not know how to do that. I have a view model: public class CustomViewModel { public

I'm trying to implement some middleware in .NET Core that rounds decimals to 2 decimal places. All of the other mapping can work as it currently does via the ComplexTypeModelBinder . I've tried calling that binder before mine or inheriting from it, but it ends up with the model just being null when it hits the controller. Essentially I'm after the same functionality as asked here: Call Default Model Binder from a Custom Model Binder? , but for .NET core. user11955020 public enum OPERATION { none, add, del, edit, excel } [ModelBinder(BinderType = typeof(JqGridModelBinder))] public class

What's the WebApi [FromUri] equivalent in ASP.NET MVC?

阅读更多关于 What's the WebApi [FromUri] equivalent in ASP.NET MVC?

In WebApi I can decorate a parameter on a controller action with [FromUri] to have the components of the URI 'deserialized', if you will, into a POCO model; aka model-binding. Despite using MVC since 2.0, I've never used it for websites (dunno why). What's the equivalent of it in ASP.NET MVC 5? The attribute doesn't seem to be recognised in the IDE unless I need to reference a library. I'd like ~/thing/2014/9 to bind to the model below: public class WhateverModel { public int Year { get; set; } public int Month { get; set; } } Thanks Update In the other question (link above), the OP says:

问题 So I have a Collection of User objects, which should be mass-editable (edit many users at the same time). I'm saving the user input to the database using Entity Framework. The collection the controller method gets from the form is null. Why? Also, is the BindAttribute possible to use with collections like in my code?
