if you use singleton class then you can send message at any screen and use Binding and
INotifyPropertyChanged Interface class to show the message in any screen.

Please make it as correct answer if it helps you!!!!!!
Sujeet Raman11y ago
yup thanx.letme try singleton pattern.i have to send message in second page and that message should display in the screen.what i can do?
Suresh M11y ago
Hi i checked your code.Problem is you are not maintain the xmpp connection properly .If you need the xmpp connection in different screen ,then you need to implement the singleton class.

now run the app and send the message in the same screen.

For testing

Install gajim and login with one user account(user1)

Now run your WPH app and login with another user(user2)

after successful login in WPH enter your To JID and send the message.

----------------------------------------------------------------
This XMPP library doesn't support MUC(group chat) protocol. You need to rewrite the xmpp library.
Sujeet Raman11y ago
i send the project,please help me how to create group chat and all
Suresh M11y ago
install Gajim client for testing
http://gajim.org/downloads.php?lang=en

Send your sample project i will check and help you
