UndoEngine::UndoUnit::UndoCore Method ()

 

Called by Undo to perform an undo action.

Namespace:   System.ComponentModel.Design
Assembly:  System.Design (in System.Design.dll)

protected:
virtual void UndoCore()

The Undo method calls the UndoCore method to perform an undo operation. The Undo method itself works to maintain consistent state within the UndoEngine::UndoUnit, even in the event of an exception thrown by UndoCore.

Notes to Inheritors:

Do not call the UndoCore method directly; override it if you want, but always call the publicUndo method to perform undo work. The Undo method notifies the undo engine to suspend undo-operation data gathering until the current undo operation is completed. This prevents new undo units from being created in response to this unit doing work.
