Raw Notification Handling in UI inside my App in Windows Phone 8 - user-interface

Question

Can some one help me out in showing a TextBox in all screens after parsing a Raw Notification data. I'm successfully able to show this data on a MessageBox like the code below but unable to show in TextBox and I want this TextBox to be called from any screen in my app. How can I do this?
public void PushChannel_HttpNotificationReceived(object sender, HttpNotificationEventArgs e)
{
string message;
using (System.IO.StreamReader reader = new System.IO.StreamReader(e.Notification.Body))
{
message = reader.ReadToEnd();
}
Debug.WriteLine("This is a "+message);
var RawNotification = (RawData)serializer.ReadObject(e.Notification.Body);*/
Dispatcher.BeginInvoke(() =>
MessageBox.Show(String.Format("Received Notification {0}:\n{1}",
DateTime.Now.ToShortTimeString(), message))
);
}

I did this for one of my app. I Don't know if this is correct way of doing it or not but it solved my purpose.
1) First Create a UserControl in whatever look and feel you want to have. Make sure you create a Public Variable that will accept String ( In this case your Message )
2) Create a method in App.xaml.cs with String parameter ( To Pass your message string ). Withing the Method, Do a Dispatcher which will call a Messagebox with Content as the usercontrol. When invoking the UserControl, Pass your message as parameter.
Now whenerver or wherever you want to display a message, Use this method from App.xaml.cs and then you can create this textbox update.
