In this post I will show you, how you could get Address from contact and Display it.

Expected Output

1. On running of application you will get a button
2. On click of button Contact list will be open
3. On selection of a contact . address of that contact will be displayed in label.

Design the page

I am going to put a very simple design. Design would have just one button and label.

On click event of the button, contact list would be open and on user selection of a contact, we will display address of that contact in label.  We are going to do very simple stuff . Don’t we ?

Content Grid of MainPage.Xaml would be looking like below,

Write the Code

Add namespace

Globally defined a variable of type AddressChooserTask

In constructor of page create instance of AddressChooserTask and register completed event on that.

In the event, check whether TaskResult is equal to TaskResult enum OK. If yes then display name and address in label.

On click event of button, we will show the contact using addressChooserTask.Show

For you reference full source code of code behind is as below,

MainPage.Xaml.cs

using System;
using System.Windows;
using Microsoft.Phone.Controls;
using Microsoft.Phone.Tasks;


namespace AddressChooser
{
    public partial class MainPage : PhoneApplicationPage
    {

        AddressChooserTask addressChooserTask;

        public MainPage()
        {
            InitializeComponent();
            addressChooserTask = new AddressChooserTask();
            addressChooserTask.Completed += new EventHandler<AddressResult>(addressChooserTask_Completed);

        }

        private void addressChooserButton_Click(object sender, RoutedEventArgs e)
        {
            try
            {
                addressChooserTask.Show();
            }
            catch (System.InvalidOperationException ex)
            {

            }

        }

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

        }
    }
}

Now when you run phone application you should get the expected output.
