Silverlight: how to disable browser refresh button?

Question

I am working on a Silverlight application (i.e. without HTML content), and one of the biggest complaints is that if a user accidentally lands on F5, the application restarts.

So is it possible to disable the Refresh button in the browser? Or at least handle F5?

Here are some options.

From the link:

One option is to connect the "onbeforeunload" object to the window and ask the user to confirm refresh / exit. Here is a simple example that you can define in your HTML markup or even release from an SL application (if it has DOM access):

<script type="text/javascript"> window.onbeforeunload = function() { return "Leaving or refreshing this page can result in data loss."; } </script>
