How does the localization feature work for validations?

[sturlath]

I have been trying to figure out how to localize validation error messages, without luck.

I have tried various versions of this but I think this is close to what I should be doing.

The razor code

<Validation Validator="@ValidateName" MessageLocalizer="@Localize">
  <TextEdit @bind-Text="@MyModel.Name">
  </TextEdit>
</Validation>

the validation logic

private void ValidateName(ValidatorEventArgs e)
{
    var name = Convert.ToString(e.Value);

    if (string.IsNullOrEmpty(name) || name.Length > 50)
    {
        e.Status = ValidationStatus.Error;
    }
    else
    {
        e.Status = ValidationStatus.Success;
    }
}

The localize message

string Localize(string message, IEnumerable<string> arguments)
{
  // just hardcoding it for testing...
  return "This not showing up...";
}

The property on MyModel

[Required]
[StringLength(50, ErrorMessage = "Name is too long.")] 
public string Name { get; set; }

What I´m I doing wrong? I have tried to skip the attributes/ErrorMessage on the property etc. etc.

Hope you can assist :-)

MessageLocalizer localization works only with data annotations. You need to remove Validator="@ValidateName". Or if you still want to use Validator then set the message by e.ErrorMessage = "something"; inside of ValidateName.

Ok I was missing the ErrorText on e!

For completeness for others here is what I did

private void ValidateName(ValidatorEventArgs e)
{
    var name = Convert.ToString(e.Value);

    if (string.IsNullOrEmpty(name))
    {
        e.Status = ValidationStatus.Error;
        e.ErrorText = localizer["PleseEnterNameOfLiveEvent"];
    }
    else if(name.Length > 50)
    {
        e.Status = ValidationStatus.Error;
        e.ErrorText = localizer["NameCanNotBeLongerThan50"];
    }
    else
    {
        e.Status = ValidationStatus.Success;
    }
}

<Validation Validator="@ValidateName">
    <TextEdit @bind-Text="@MyModel.Name">
        <Feedback>
            <ValidationError></ValidationError>
        </Feedback>
    </TextEdit>
</Validation>

[Required]
[StringLength(50)] 
public string Name { get; set; }

Works like a charm!
