<div class="markdown level1 remarks"><p>This method clears all recorded operations from both the undo and redo stacks. It is useful when the state of the document changes in such a way that
previous operations are no longer relevant or applicable. After clearing the history, the <a class="xref" href="GrapeCity.ActiveReports.Design.UndoManager.Changed.html">Changed</a> event is raised to notify subscribers
that the undo/redo history has been reset. Additionally, if any subscribers are registered to the <span class="xref">GrapeCity.ActiveReports.Design.UndoManager.Reset</span> event, it is also raised to signal
a complete reset of the undo/redo system.</p>
