Questions tagged [model-validation]

Model Validation is ASP.NET MVC validation method for your models with property attributes. Model validation works for client and server side validation.

For further information you can check Scott Gu's blog post: http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx

There is a expansion called "DATA ANNOTATIONS EXTENSIONS" for other custom validation types such as CreditCard, min-max integer value etc. http://weblogs.asp.net/srkirkland/archive/2011/02/23/introducing-data-annotations-extensions.aspx
