  Its been so long since I did it for the first time.

  No, DataType has no builtin validation

  Well if that's the case, heres some code, note that I work with jQuery validate so you might need to do even more to get this working on the client:

  
  

  public class DataTypeValidator : DataAnnotationsModelValidator<DataTypeAttribute>
      {
          public DataTypeValidator(ModelMetadata metadata, ControllerContext context, DataTypeAttribute attribute)
              : base(metadata, context, attribute) {
                  this.message = attribute.ErrorMessage;
          }
  
  
          string message;
  
  
          public override IEnumerable<ModelValidationResult> Validate(object container)
          {
              //TODO: Add email and url regularexpression validations.
              return base.Validate(container);
          }
  
  
          public override IEnumerable<ModelClientValidationRule> GetClientValidationRules()
          {
              List<ModelClientValidationRule> rules = new List<ModelClientValidationRule>();
  
  
              ModelClientValidationRule rule;
              switch (Attribute.DataType)
              {
                  case DataType.EmailAddress :
                      rule = new ModelClientValidationRule() { ErrorMessage = message, ValidationType = "email" };
                      rule.ValidationParameters.Add("email", "true");
                      rules.Add(rule);
                      break;
                  case DataType.Url :
                      rule = new ModelClientValidationRule() { ErrorMessage = message, ValidationType = "url" };
                      rule.ValidationParameters.Add("url", "true");
                      rules.Add(rule);
                      break;
              }
  
  
              return rules;
          }
      }

  
  And add that RegisterAdapter line of code from my earlier post to your application_start

  Use nuget to install MVC2(or 3) futures project.  You can use the EmailAddressAttribute.  It's also a good reference for how to extend it (and unobtrusively) if you need to.
