How to use the address chooser task for Windows Phone 8

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Use the address chooser task to obtain the physical address of a contact selected by the user. This task launches the Contacts application so that the user can choose a contact. If the user completes the task, an event is raised and the event handler receives an address in the result.

By using Choosers, you help provide a consistent user experience throughout the Windows Phone platform. For more information, see Launchers and Choosers for Windows Phone 8.

Note

The Windows Phone SDK includes APIs that you can use to retrieve contact information from within your application. For more information, see Contacts and Calendar for Windows Phone 8.

To use the address chooser task

1. Add the following statement to your code.

   using Microsoft.Phone.Tasks;
   

   Imports Microsoft.Phone.Tasks
   

2. Declare the task object. It must have page scope, so declare it in your page before the constructor.

   AddressChooserTask addressChooserTask;
   

   Dim addressChooserTask As AddressChooserTask
   

3. Add the following code to your page constructor. This code initializes the task object, and identifies the method to run after the user completes the task.

   addressChooserTask = new AddressChooserTask();
   addressChooserTask.Completed += new EventHandler<AddressResult>(addressChooserTask_Completed);
   

   addressChooserTask = new AddressChooserTask()
   AddHandler addressChooserTask.Completed, AddressOf addressChooserTask_Completed
   

4. Add the following code to your application wherever you need it, such as in a button click event. To test this procedure, you can put the code in the page constructor. This is the code to launch the task.

   
   
   addressChooserTask.Show();
   
   
   
   
   

   
   addressChooserTask.Show()
   
   
   
   

5. Add the code for the completed event handler to your page. This code runs after the user completes the task. The result is an AddressResult object that contains the name and address of the contact.

   void addressChooserTask_Completed(object sender, AddressResult e)
   {
       if (e.TaskResult == TaskResult.OK)
       {
           MessageBox.Show("The address for " + e.DisplayName + " is " + e.Address);
       }
   }
   

   Private Sub addressChooserTask_Completed(sender As Object, e As AddressResult)
   
       If e.TaskResult = TaskResult.OK
   
           MessageBox.Show("The address for " + e.DisplayName + " is " + e.Address)
       End If
   End Sub
