To use the save contact task

  1. Add the following statement to your code.

    using Microsoft.Phone.Tasks;
    
  2. Declare the task object. It must have page scope, so declare it in your page before the constructor.

    SaveContactTask saveContactTask;
    
  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.

    saveContactTask = new SaveContactTask();
    saveContactTask.Completed += new EventHandler<SaveContactResult>(saveContactTask_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.

    You can pre-populate the properties, but it is not required. The user can add and edit all the properties before saving. For the full list of available properties, see SaveContactTask.

    
    
    
    saveContactTask.FirstName = "John";
    saveContactTask.LastName = "Doe";
    saveContactTask.MobilePhone = "2065550123";
    
    saveContactTask.Show();
    
    
    
    
    
    
    
  5. Add the code for the completed event handler to your page. This code runs after the user completes the task. You can check to see whether the contact was saved successfully.

    void saveContactTask_Completed(object sender, SaveContactResult e)
    {
        switch (e.TaskResult)
        {
            //Logic for when the contact was saved successfully
            case TaskResult.OK:
                MessageBox.Show("Contact saved.");
                break;
    
            //Logic for when the task was cancelled by the user
            case TaskResult.Cancel:
                MessageBox.Show("Save cancelled.");
                break;
    
            //Logic for when the contact could not be saved
            case TaskResult.None:
                MessageBox.Show("Contact could not be saved.");
                break;
        }
    }
