Site now allows promotion codes. If the promotion brings the payment amount to 0 the client doesnt want to require credit card information to be entered. Currently the ViewModels have required on the CC information. Now need to make it conditional. Any way to do this through attributes?

What you basically want is a [RequiredIf] data annotation attribute, unfortunately this is not built into MVC4, but the good news is that there is a nuget package available. The alternative is of course to write your own server and jquery unobtrusive validation method yourself which isn't too hard.
你基本上想要的是[RequiredIf]数据注释属性,遗憾的是这并没有内置到MVC4中,但好消息是有一个nuget包可用。另一种选择当然是自己编写自己的服务器和jquery不显眼的验证方法,这不是太难。
Have a look at RequiredIf on https://foolproof.codeplex.com/ and to install the package, simply use the NuGet package console and install-package foolproof, or search for foolproof in the package manager.
