RadSpellChecker

Provides functionality for checking spelling in various types of controls. The class allows for spell checking in two modes: word-by-word and all at once. It manages the display of custom windows for error correction and handles the completion of spell checking tasks through events. The spell checker configuration and window display settings are customizable through the WindowSettings property. It raises the SpellCheckingCompleted event to signal when the spell checking operation is complete, allowing for appropriate responses or notifications to be triggered once checking is finished.
