When the DevExpress ASP.NET Web Forms Spell Checker finds a word missing from dictionaries, the control displays the check spelling form. This form allows users to correct, skip, or ignore the word. In this example, the ASPxSpellChecker control corrects spelling automatically.
[!NOTE]
In the example, the Spell Checker replaces a misspelled word with the first word from the suggestion list. As a result, the control may correct words incorrectly.
