The Spell Checker for WPF supports the following dictionaries:

  • Simple
  • ISpell
  • OpenOffice
  • Hunspell
  • Custom

You can add multiple dictionaries to the spell checker’s dictionary collection or share dictionaries between multiple spell checkers.

Customize Spell Check UI


You can customize or hide the following UI elements:

Spelling Dialog
This dialog is used to make corrections: select one of the suggested corrections to replace a misspelled word (either once or all occurrences), skip the word, ignore the word and all its further occurrences, or add the word to a custom dictionary.
Spelling Options Dialog
Allows users to adjust Spell Checker behavior (ignore words in upper case, mixed case, words that contain numbers, and so on), edit the custom dictionary, and change the language of the selected text to use the corresponding proofing dictionary.
