## Remarks
  
This method can be used only if you have already called the [Undo()](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_WinControls_MultiLayerViewer_Undo.htm.md) method). If no undone states are available, the method will fail. You can check if the undone states exist using the [CanRedo](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_WinControls_MultiLayerViewer_CanRedo.htm.md) property.
