Installation

You can download the latest release / pre-release NuGet packages from the official NuGet pages:

Getting started

  1. Add a reference to Morris.Blazor.Validation
  2. Inside the <EditForm> in your razor files, add <Morris.Blazor.Validation.Validate/>
  3. In startup.cs add using Morris.Blazor.Validation and then add the relevant validation in the ConfigureServices method.
  • services.AddFormValidation(config => config.AddDataAnnotationsValidation());
  • services.AddFormValidation(config => config.AddFluentValidation(typeof(SomeValidator).Assembly));

It is possible to add as many validation providers as you wish

services.AddFormValidation(config => 
  config
    .AddDataAnnotationsValidation()
    .AddFluentValidation(typeof(SomeValidator).Assembly)
);

Also you can have the FluentValidation extension scan multiple assemblies

services.AddFormValidation(config => 
  config
    .AddFluentValidation(
      typeof(SomeValidator).Assembly,
      typeof(ClassInAnotherDll).Assembly,
      andAnotherAssembly,
      andYetAnotherAssembly));

The standard Blazor components <ValidationSummary> and <ValidationMessage> will now work with your selected validation options.

Sample projects

More sample projects will be added as the framework develops.
