[Description("The UndoManager for this model.")]
publicUndoManager UndoManager {get; set;}
Property Value
This value may be null, when there is no UndoManager. By default this value is null. If this value is null, it is automatically set to a new UndoManager when HasUndoManager is changed to be true.
Remarks
Of course, when there is no UndoManager, the user cannot perform an Undo or a Redo. Setting this property does not raise a Changed event. Setting this property may also change the value of HasUndoManager.
