Remarks

Use the ShowValidationIcon global option to specify whether Blazor editors should show validation icons - error or success .

You can specify this option in a few different ways:

• Call the AddDevExpressBlazor(IServiceCollection, Action<GlobalOptions>) method.

  Program.cs

  using DevExpress.Blazor;
  
  builder.Services.AddDevExpressBlazor(configure => configure.ShowValidationIcon = true);
  

• Call the services.Configure method that registers a configuration instance with the specified global option’s value.

  Program.cs

  using DevExpress.Blazor;
  using DevExpress.Blazor.Configuration;
  
  builder.Services.Configure<GlobalOptions>((options) => options.ShowValidationIcon = true);
  

• Define the global option’s value in the appsettings.json file.

  appsettings.json

  { 
      "DevExpress": { 
          "ShowValidationIcon": "true" 
      } 
  } 
  

  Call the services.Configure method. Use the ConfigurationBinder.Bind method to register a configuration instance with the specified global option’s value.

  Program.cs

  using DevExpress.Blazor;
  using DevExpress.Blazor.Configuration;
  
  builder.Services.Configure<GlobalOptions>(options => builder.Configuration.Bind("DevExpress", options));
  

You can also specify the ShowValidationIcon property for each editor individually.
