WP8 Notification Param

Question

Hello, 

I develop a app for wp8.

When the app is active the notification sent from the App42 portal arrive correctly

Whe the app is not active it appear as notification and when I tap on it will open the application 

but I can't read the message.

I the documentation I found:

       protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
        {
            base.OnNavigatedTo(e);

            //  If we navigated to this page
            // from the MainPage, the DefaultTitle parameter will be "FromMain".  If we navigated here
            // when the secondary Tile was tapped, the parameter will be "FromTile".
            textBlockFrom.Text = "Navigated here from " + this.NavigationContext.QueryString["NavigatedFrom"];

        }

But when I use this and when I tap on the message in the notification bar the query string is always empty.

reading on internet I see that the format of notification can contain this values:

wp:text1 (In this fiels I found the message)

wp:text2 (never found )

wp:Param (never found)

 

In particulari in the wp:Param I read that I can setup the query string for the app.

Can you help me ?

I need to read the notification received whe app is in background or not active.

 

Best regards

Hi Gabriele Fain,

 

Apologies for getting late back to you.

 

For sending param with push notification please read our tutorial http://api.shephertz.com/tutorial/Push-Notification-WindowsPhone/#sending-toast-message-to-user, you can add parameters somethong like

 

String param = /MainPage.xaml?ID=1

 

There is not direct way to read push notification in background but you can achieve this by using background agents provided by Windows phone for detail please have a look on this link also.

Let me know if it helps.

Hello,
I cannot use SendPushToastMessageToUser because I send the notification from a java program that send notification to the user, and I don't know if the user have a IOS, ANDROID or WP8 phone.
So I use the sendPushMessageToUser function that is generic, but I need to add the param for toast.

There is a way to do this ?
Best regards
