Masking Textbox without affecting Model value in ASP.NET MVC

I need to mask the input box/text box in ASP.NET MVC 2 for Credit Card. But the masking shouldn't affect its bind开发者_StackOverflow社区ing to its model.

I am trying to do something like this: [DataType(DataType.MaskedCreditCard)] similar to: [DataType(DataType.Password)]
