Visual Elements
The DevExpress WinForms Spell Checker ships with all UI elements you'll need to fully replicate the spell checking user experience available in Microsoft Word or Microsoft Outlook.
Customizable Spell Checking Dialogs
Built-in spelling error indication forms.
Customizable Spell Checking Dialogs
Choose one of two spelling error indication dialogs - both replicate dialogs found in Microsoft Office (Outlook & Word). In addition, the control includes Dictionary dialogs so that end-users can add unrecognized words to their dictionary. As you would expect, end-users can build a custom word list as needs dictate.
Spelling Options Dialog
Built-in spell checking options dialog.
Spelling Options Dialog
From general options such as "ignore uppercase" to editing custom dictionary entries and language selection, the Options Dialog allows end-users to modify spell checking behavior as necessary.
Popup (Context) Menu
Integration with Popup Menus.
Popup (Context) Menu
You can automatically embed Custom Items (suggestions, etc) to the context menu to simplify error correction (without the need to invoke a dialog).
Check-as-You-Type Mode
Intuitive error indication.
Check-as-You-Type Mode
Errors can be underlined using wavy red lines. The control automatically checks spelling as you type, word by word in a separate thread without affecting UI responsiveness.
