On your calling window:

ChildWindow w = new ChildWindow ();
w.Owner = this; //here your calling window
w.Show();

On your child window:

(this.Owner as YourMainWindow).YourProperty  = "Your Text";

the Owner property is a Window, so if you want to access a your custom property you have to cast to your window type.

In your case, using a Page, add this proprerty to your LobbyStandardPopupView:

 public LobbyStandardView mycallingpage = null;
 public LobbyStandardPopupView(LobbyStandardView callingPage)
 {
     InitializeComponent();
     mycallingpage = callingPage;
 }

and in your button event:

mycallingpage.Ring_Game.Text = "Hello";
