Remarks

Call the AddSpellCheck method to register external spell check services within the following options:

AddToDictionaryAction

Allows you to implement a delegate method that writes the selected word to a dictionary file. The Rich Text Editor executes this method after a user clicks the Add to dictionary command in the context menu. If you do not set the AddToDictionaryAction property value, the component hides the command.

Dictionaries

Stores a list of dictionaries you added. To extend the dictionary list, pass a simple, ISpell, or Hunspell dictionary to the list’s Add method.

FileProvider

Specifies a file provider that accesses dictionary files. The FileNotFoundException error occurs if you add a dictionary without specifying a file provider.

MaxSuggestionCount

Specifies the maximum number of suggestions that the Rich Text Editor should display in its context menu. The component can display up to 15 suggestions.

The following code snippet retrieves a logging service within the AddToDictionaryAction:

Program.cs

var builder = WebApplication.CreateBuilder(args);
// ...
builder.Services.AddSingleton<ILoggingService, LoggingService>();
builder.Services.AddDevExpressBlazor().AddSpellCheck((options, serviceProvider) => {
    options.AddToDictionaryAction = (word, culture) => {
        var loggingService = serviceProvider.GetRequiredService<ILoggingService>();
        loggingService.LogWord(word);
    };
});
// ...
var app = builder.Build();
