AddUndoUnit Method

Adds the current state of the header or footer to the undo stack. Programmatic changes performed with the header's or footer's properties and methods are not automatically added to a TextControl's undo stack. Calling this method is not necessary, when the header's or footer's text and/or formatting is changed.
