The DevExpress Blazor Rich Text Editor ships with a built-in spell check service that can detect spelling errors and suggest corrections. Review demo source code to learn how you can enable and configure this service as business needs dictate.

Configuration involves two steps:

• Register a spell check service.
  Call the AddSpellCheck extension method. In this method call, you can customize service options.

• Enable spell check within the Rich Text Editor control.
  Set the component's CheckSpelling property to true.

The DocumentCulture property specifies the culture name for an open document. Depending on document culture, the service determines which dictionaries to use.

If the built-in service does not address your requirements, you can implement and use a custom spell check service.
