Property Value

The undo stack contains the operations in last-in-first-out order: The first element is the operation that was executed last and that needs to be undone first.

This is a read-only collection and should only be used to read information about the most recently executed operations. The operations on the undo stack should not be manipulated directly. Call Undo or Redo to undo or redo operations.
