Built-in Dialogs and Check as You Type Mode
Spell Checking Dialogs: Allow end-users to add unrecognized words to a dictionary. As one would expect from this type of control, end-users can build a custom word list if required. Spelling options allow you to ignore emails, URLs, mixed case/upper-case words, repeated words and words with numbers within them.
Check as You Type: Whether you use DevExpress or standard text input controls, words that aren't in the dictionary can be underlined with straight or wavy red lines. When activated, the ExpressSpellChecker automatically checks spelling as you type, word by word in a separate thread without affecting UI responsiveness.
