问题 MVC isn't generating the client-side validation rules for my viewmodel. The HTML just contains this: <script type="text/javascript"> //<![CDATA[ if (!window.mvcClientValidationMetadata) { window.mvcClientValidationMetadata = []; } window.mvcClientValidationMetadata.push({"Fields":[],"FormId":"form0","ReplaceValidationSummary":false}); //]]> </script> Note that Fields[] is empty! My view is strongly-typed and uses the new strongly-typed HTML helpers ( TextBoxFor() , etc). View Model / Domain

问题 I'm trying to implement comet in my ASP.Net MVC 2.0 project. I'm using WebSync from FrozenMountain. My website is coded in C# 4.0 and ASP.Net 4.0. The comet code is triggering my MVC controller function with the [HttpPost] attribute (even though the page doesn't refresh or appear to post).

Please note, I know how to ignore routes with MVC, that is not the issue. 回答1: The gentlemen at Frozen Mountain

问题 OK, so I've been working on this for hours. I've found a couple of posts here, but nothing that actually resolves the problem. So, let me try it again... I have an MVC2 app using Ninject and a custom membership provider. If I try and inject the provider using the ctor, I get an error: 'No parameterless constructor defined for this object.' public class MyMembershipProvider : MembershipProvider { IMyRepository _repository; public MyMembershipProvider(IMyRepository repository) { _repository =

问题 I have an application that I've been using xVal successfully on for quite some time. It was recently updated to MVC 2. I use the standard DataAnnotations attributes on my domain models, which also implement a "Validate()" method that calls the DataAnnotationsValidationRunner. If there are any errors, that method throws a RulesException. In my controllers, I use the very typical catch for RulesException catch (RulesException e) { e.AddModelStateErrors(ModelState, "err"); } All typical stuff,
