Unfortunately, you simply can't re-open a Window after it has been closed. However, you can 'pretend' that you can and use a little deception... instead of closing the Window in the first place, you could simply hide it, as it can be hidden and re-displayed any number of times:
You could improve this situation slightly perhaps, by attaching an event handler to the Window.Closing Event. This particular event provides a way to cancel the Close operation and so at this point, you could hide it instead:
You could alternatively put this functionality inside the Window code behind using the Window.OnClosing Method if you preferred.
