asp.net mvc IDataErrorInfo validation when using ViewModel


asp.net mvc IDataErrorInfo validation when using ViewModel



I have used IDataErrorInfo Validation for my Model. But when I use these model classes inside a view model, the validation does not happen.

sample viewmodel below

public class CategoryViewModel     {     // Category class with IDataErrorInfo     public Category category { set; get; }      // Subcategory class with IDataErrorInfo     public IList<SubCategory> subcategory { set; get; } } 

Now, if Category or Subcategory classes are directly used as models for view, the validation works fine. But, if CategoryViewModel is used, no validation occurs.
