Dear All,

I am trying to implement localization to stringlength attribute for all models with the same way i have localized the DisplayName attribute.
The only change is that i will take the new value from the core class mapped attribute not from a resource file.

I am using EntityFramework with CodeFirst

Can anyone help me with that?

Here is my Code:

so suppose i have the core class [Employee] as following:

public class Employee
    {                
        [Key]
        public int EmployeeId { get; private set; }

        [Required, StringLength(500), Index("IX_Employee_EmployeeName", IsUnique = true)]
        public string EmployeeName { get; private set; }
        
    }

Now i have the Model class [EmployeeModel] as following:

[MetadataType(typeof(MetaDataProvider))]
    public class EmployeeModel
    {
        public int EmployeeId { get; set; }

        public string EmployeeName { get; set; }

    }

Here is my MetaDataProvider Class

public class MetaDataProvider : DataAnnotationsModelMetadataProvider
    {
        protected override ModelMetadata CreateMetadata(IEnumerable<Attribute> attributes,
                                                        Type containerType,
                                                        Func<object> modelAccessor,
                                                        Type modelType, string propertyName)
        {
            var result = base.CreateMetadata(attributes, containerType, modelAccessor, modelType, propertyName);

            if (string.IsNullOrEmpty(result.DisplayName) && containerType != null && propertyName != null)
            {
                var keyForDisplayValue = string.Format("{0}_{1}", containerType.Name, propertyName);
                var translatedValue = HR.Resources.DisplayInputsAR.ResourceManager.GetObject(keyForDisplayValue) as string;

                if (!string.IsNullOrEmpty(translatedValue))
                {
                    result.DisplayName = translatedValue;
                }
            }

            return result;
        }
    }

Now i want [EmployeeModel.EmployeeName] to be with the same length of [Employee.EmployeeName].
