# TextControl.SpellChecker Property

> Specifies the spell checking component to be used with a TextControl. The property value must be the key of a resource added to the Resources dictionary of a TextControl or a parent of a TextControl in the logical element tree of the application. The resource key must be a string. Specifying an empty string, a connected spellchecker can be disconnected. When a spell checking component is connected and the IsSpellCheckingEnabled property has been set to true, misspelled words are automatically underlined with a red zigzag line. The SpellCheckDialog method can be used to correct the misspelled words contained in the document. When a spell checking component is connected and the IsHyphenationEnabled property has been set to true, a document is automatically hyphenated. If the IsLanguageDetectionEnabled property has been set to true, a language is automatically detected for all text parts with a neutral language.
