We are using a data grid component which requires validation to be performed within the dto class. The validation works, but we are unable to use a localized error message within the class. Is there a way to refer to the localization resource from within the dto?

For eg:

public class ApplicationValidationActionFlatDto
{

    public Guid Id { get; set; }
    public string TaskDescription { get; set; }
    public string Result { get; set; }

    [CustomValidationResultDate]
    public DateTime ResultDate { get; set; }
    public Guid? ResultedById { get; set; }
    public string Comments { get; set; }
    public int Order { get; set; }
    public Guid ApplicationProcessId { get; set; }
    public Guid LicenceTypeValidationId { get; set; }

}

public class CustomValidationResultDate : ValidationAttribute
{

    protected override ValidationResult IsValid(object value, ValidationContext validationContext)
    {

        if (value != null)
        {

            var d = Convert.ToDateTime(value);
            if (d.Year.ToString().Length < 4)
            {
                return new ValidationResult("ValidationMessageResultDate");
            }
            else if (d < DateTime.Now)
            {
                return new ValidationResult("ValidationMessageResultDateLessThanCurrentDate");
            }

        }

        return ValidationResult.Success;

    }

}

In CustomValidationResultDate Class, the parameter of ValidationResult Class is not able to be set to a localized string.

    Hi,

    I'm sorry, but I don't understand how those links show localisation in dtos. I don't want to change our validation component - we are using a third party component which uses this validation type. The validation itself is working. What I'm unsure of is if I can inject our Localisation resource into a dto to reference that for the error message which currently is a hard-coded string. The links above also use a hard-coded error message string. Is there anything I can do?

    hi

    You just need to inject the services in the IsValid method.

    var myService = validationContext.GetRequiredService<IMyService>();

    You can also manually validate in the application service method.
