The Data Annotations Validator Component for Blazor to localize validation error messages, based on "Microsoft.Extensions.Localization".

Localized Data Annotations Validator Component for Blazor

Summary

This is the Data Annotations Validator Component for Blazor to localize the validation error messages, based on Microsoft.Extensions.Localization.

Live Demo - https://demo-blazor-localized-data-annotations-validator.azurewebsites.net/

[NOTICE]

This component will works fine on "Server-side Blazor", not "Client-side Blazor" at this time.

The supporting of Microsoft.Extensions.Localization based localization on Client-side Blazor is weak, therefore it will need some hacks. (see also: https://dev.to/5argon/comment/gdch)

Another way, "Blazor I18n Text" service will work fine on both Server-side Blazor and Client-side Blazor. However, it is not integrated Microsoft.Extensions.Localization based localization at this time.

How to use?

Step 1. Setup "IStringLocalizer" infrastructure on your Blazor app

See also:

• "Globalization and localization in ASP.NET Core | Microsoft Docs"

Of course, you should create resource files (.resx) for data annotation validation error messages, too.

Step 2. Install this package

Like this:

> dotnet add package Toolbelt.Blazor.LocalizedDataAnnotationsValidator

Step3. Replace the data annotations validator component

Rewrite the implementation of the validation on your app.

At first, open the "Toolbelt.Blazor.Forms" namespace, in the _Imports.razor.

...
@using Toolbelt.Blazor.Forms

Next, replace the DataAnnotationsValidator to LocalizedDataAnnotationsValidator.

For example, in your .razor file, rewrite it from:

<EditForm Model="..." ...>
  <DataAnnotationsValidator />
  ...

to:

<EditForm Model="..." ...>
  <!-- �« Replace this component! -->
  <LocalizedDataAnnotationsValidator />
  ...

That's all!

toolbelt.blazor.localizeddataannotationsvalidator's Issues

Using this for managing .net Core Identity Data Annotations

Hi,

Can this be used also for localizing .net Core identity that is a part of Blazor Server project?

As in cshtml files we do not have component for <DataAnnotationsValidator />

Can it work with SharedResource?

Not an issue, just a question :) If yes, how?
