Property Value
true if the user can undo the previous operation performed in this AnnAutomation; otherwise, false.
Remarks
If this property value is true, you can call Undo to undo the previous operation performed in this AnnAutomation. You can use this property to update your user interface; for example, to enable/disable an Undo menu item. Use the UndoCapacity property to get or set the number of user actions that can be reversed using the Undo method, or re-applied using the Redo method. The default for the UndoCapacity property is 10 actions.
For more information, refer to Undoing WPF Automation Operations.
Please note that the Undo operation does not work for the Realize operation that has been performed with the RealizeRedaction method to realize the entire image.
Example
For C#/VB examples, refer to UndoRedoChanged.
