Question

I send toast notification to mobile with Windows Phone 7. When I'm out of application I get bar at top on screen with my title and description. That is great.
But how can I handle event when I click this bar?

Answer 1

You can specify a page that the user will be navigated to along with parameters when your app opens via clicking on the toast notification. It's called deep linking and you can read about it on MSDN .

The XML that you send should include an additional element called Param .

<wp:Param>[stuff goes here]</wp:Param>

You have three options of what you can supply:

/page1.xaml – Defines the screen to navigate to in the app when the app starts. The string must begin with a "/".

/page1.xaml?value1=1234 &value2=9876 – Defines the screen to navigate to when the app starts, along with name/value pairs of info. The string must begin with a "/".

?value1=1234 &value2=9876 – Contains name/value pairs of info passed to the default start screen of the app. The string must begin with a "?".

You can then then pick these up in your page like so:

protected override void OnNavigatedTo(NavigationEventArgs e)
{
    string strVal1 = this.NavigationContext.QueryString["value1"];
}
