Goal of this article to get a best way to implement validation of input values in my and your applications. I want to talk about all of these approaches, about pros and cons of using each of them.
Two other ways (both of them is came with Silverlight 4) – you should implement one of interfaces for your ViewModel: IDataErrorInfo or INotifyDataErrorInfo.
