* Integrated multi-language spell checking for any text field. With Infragistics WinSpellChecker, you can check the spelling of any text based control, including TextBoxes, RichTextBoxes, and any object that implements the IProvideTextBox or ISupportSpellChecking interfaces. The WinSpellChecker component can check spelling as the end user types, and automatically correct commonly misspelled words. Misspelled words are underlined with the familiar red 'squiggly' line.
