model-binding

问题 Let's say I have an User entity and I would want to set it's CreationTime property in the constructor to DateTime.Now. But being a unit test adopter I don't want to access DateTime.Now directly but use an ITimeProvider : public class User { public User(ITimeProvider timeProvider) { // ... this.CreationTime = timeProvider.Now; } // ..... } public interface ITimeProvider { public DateTime Now { get; } } public class TimeProvider : ITimeProvider { public DateTime Now { get { return DateTime.Now;

问题 I have problem with form panel and binding modelView in ExtJS 5. When form panel after render, values set slowly.

问题 For some reason I'm trying to manually bind an array of a Complex Model but I'm getting a null reference exception in my controller, the binder doesn't retrieve the parameter. I've found this question which is very similar (the only difference is actually the type of the model) but I don't understand why it doesn't work in my case. Here is what I have. In my controller public ActionResult MyAction(ComplexType[] models) { foreach(ComplexType c in models) // Exception at this point, the

问题 I'm having difficulty getting the Model Binder to work. I thought it was the jQuery, so I asked this question, but after further investigation, I can see that the jQuery is indeed sending the parameter to the server. That's the reason I'm asking a new question - this is no longer a jQuery issue, as I originally thought.
