Undoes the most recent undo command. In other words, undoes the most recent undo unit on the undo stack.
You cannot use methods in XAML.
Type: System.Booleantrue if the undo operation was successful; otherwise, false. This method returns false if the undo stack is empty.
The following example demonstrates how to use the Undo method.
private void undoAction(object sender, RoutedEventArgs e)
if (myTextBox.CanUndo == true)
