You could pass parameters between pages just like in HTML pages so as to update the button content. An example is mentioned here: How To: Perform Page Navigation Hope this answers your question. Sandeep.

Hmm.. well, I'll have to hand you off to the Silverlight guys then. If you don't have a reference to the page and don't want to use messenger (which is really simple IMO), then I'd think you'd need a global static class that exposes an event or holds the references there. There might be something to handle that in Silverlight that I'm not aware of. In WPF, I'd certainly use messenger to communicate between views.
