The ClearUndo method clears any undo operations available for the schedule.

The ClearUndo method prevents users from undoing operations that have been performed on the schedule. Good programming practice dictates the use of this method only if the application performs some operation that should not be undone. Otherwise, using this method can confuse the user, or cause the application to be in an unwanted state if the operation is undone.
