How to Launch Call Task From Secondary Tile in Windows Phone 7

Recently I got a mail from one of the readers. She asked "How could be launch Call Task from Secondary Tile?" In this article I am going to show the way to do that. Before proceeding with this article, I strongly recommend reading the following three posts for more on Live Tiles and Call Task.

The idea of launching a Call Task from Secondary Tiles is very simple. 

1. On clicking of Secondary Tile user will get navigated to a blank page. Let us call that page as Page1.XAML
2. On NavigatedTo method of the Page1.Xaml, we will instantiate Call Task and show call panel to user.

Let us create Secondary Tile on MainPage.Xaml. I have put a button on MainPage and on click event of the button Secondary Tile will get created. 

private void btnCreateSecondaryTiles_Click(object sender, RoutedEventArgs e)
{         
     var newTile = new StandardTileData()
     {
          Title = "Blogs Update",
          BackgroundImage = new Uri("background.png", UriKind.Relative),
          Count = 42,
      };
      var uri = "/Page1.xaml?state=Live Tile";
      ShellTile.Create(new Uri(uri, UriKind.Relative), newTile);      
}

If you notice in the preceding code, I have set navigation to Page1.Xaml. Now on onNavigatedTo() method we need to write code to launch Call Task.

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
      //base.OnNavigatedTo(e);
      PhoneCallTask callTask = new PhoneCallTask();
      callTask.PhoneNumber = "999999";
      callTask.DisplayName = "debugMode";
      callTask.Show();
}

On running you should be getting following output
