The following table shows the results of repeatedly calling this method as a user enters digits from a phone number, using a formatter set to the "US" region.

The following code snippet demonstrates a TextChanged event handler that updates a TextBlock with the formatted partial number whenever the number typed into the event handler's TextBox changes.

using Windows.Globalization.PhoneNumberFormatting;

PhoneNumberFormatter currentFormatter;

public MainPage()
{
    this.InitializeComponent();

    // Using the current default region
    currentFormatter = new PhoneNumberFormatter();
}

private void gradualInput_TextChanged(object sender, TextChangedEventArgs e)
{
    outBlock.Text = currentFormatter.FormatPartialString(gradualInput.Text);
}
