In my WPF application I am having a user control in main window and a Frame(Navigation frame) and my first page is menu page and I will navigate from menu page to other page using navigation service and here comes my question. I will be connecting to a hardware device in main window and updating the usercontrol(which shows the status of the device as connected or not) in main page and I will be using a event handler from H/W device provider dll which triggers if the connection status changed and now lets say if I am in some of the page in app and the connection got lost. How can I update the main window the control status and I can't implement the eventhandler in all the pages and I also trying with MVVM.

You can declare a public static property to store the connection status. You need to handle connection change in every form. Once connection changed occurred, change the static variable of Main form ( MainWindow.MyConnection) from that form. Shoot the notifier from set method of this property ( MyConnection).
