ExpressSpellChecker Features include:

• Built-in support for Ispell and OpenOffice dictionaries.
• Using the ExpressSpellChecker, you can check text in standard text editors.
• If you use Developer Express text input controls, words that aren't in the dictionary can be underlined. The ExpressSpellChecker automatically checks spelling as you type, word by word. This is done in a separate thread without affecting UI responsiveness.
• Plain text format custom dictionary support.
• Dictionary 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 as their needs dictate.
• A choice of two error indication dialogs - both replicate dialogs found in Microsoft Office.
• Pre-built Options editor.
• Spell checker options allow you to ignore emails, URLs, mixed case/upper-case words, repeated words and words with numbers within them.
• You can force the spell checker to start scanning the text from the current cursor position or to check the current selection first.
• Error correction using a customizable built-in context menu.
• The ExpressSpellChecker's API includes methods to check an arbitrary string, a text editor's content or all text editor controls within a specified container.
• You can handle specially designed events to fully manage the spell checking process - including suppression of built-in forms, modification to suggestion lists, skipped words, manual error processing, etc.
