This is clearly a validation issue so i thought of creating a validation attribute to perform this task. currently i have the following code and i am trying to inject IUserService. I know i could do hacks like IOC.Resolve<IUserService>() in the getter but i would like to keep my code free from coupling it with the container. thx a lot public class ValidateUniqueEmailAttribute : AbstractValidationAttribute { private readonly String _Message; public ValidateUniqueEmailAttribute(String message) { _Message = message; } public IUserService UserService { get; set; } public override IValidator Build() { var validator = new UniqueEmailValidator(UserService) { ErrorMessage = _Message }; ConfigureValidatorMessage(validator); return validator; } } and public class UniqueEmailValidator : AbstractValidator { private IUserService _UserService; public UniqueEmailValidator(IUserService userService) { _UserService = userService; } public override bool IsValid(object instance, object fieldValue) { if (fieldValue == null) return true; return _UserService.EmailExists(fieldValue.ToString()); } public override bool SupportsBrowserValidation { get { return true; } } } -- You received this message because you are subscribed to the Google Groups "Castle Project Users" group.
