Sharepoint 2010 - connection between custom webparts on different site pages.

Question

Hello!

I would be grateful if you could help me / hint me on the issue I'm struggling with at the moment.

I try to implement connection (using custom connection interface) between 2 custom web parts on different pages, essentially a "master-detail" behaviour.

If I add both web parts on the same page, they can be connected successfully. But for some reason I can't see any "Connections" menu among the options for the "provider" web part.

Do you know by any chance what could be the issue, or possibly you may know what has to be implemented additionally to connect 2 web parts located on different pages.

Thanks in advance.
