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
