Answer 2

I'm providing a more specific answer with code...

To get the desired effect, you can use a Grid and assign the same Row to both controls. Remember, since the TextBlock sits on top of the TextBox, you will need to account for the user tapping the TextBlock and also TABing into the TextBox.

XAML:

<Grid>
 <PasswordBox x:Name="PasswordTextBox" 
    Grid.Row="0" HorizontalAlignment="Left" 
    GotFocus="PasswordTextBox_GotFocus" LostFocus="PasswordTextBox_LostFocus"

 <TextBlock Name="PasswordWatermark" Text="Password" VerticalAlignment="Center"
    Grid.Row="0" Margin="20,0,0,0" Foreground="Gray" FontSize="24" 
    Tap="PasswordWaterMark_Tap" />
</Grid>

CODE BEHIND:

private void PasswordTextBox_GotFocus(object sender, RoutedEventArgs e)
{
  PasswordWatermark.Visibility = Visibility.Collapsed;
}

private void PasswordWatermark_Tap(object sender, GestureEventArgs e)
{
  PasswordWatermark.Visibility = Visiblity.Collapsed;
  PasswordTextBox.Focus();
}

private void PasswordTextBox_LostFocus(object sender, RoutedEventArgs e)
{
  PasswordWatermark.Visibility = PasswordTextBox.Password.Length > 0 
                                    ? Visibility.Collapsed
                                    : Visibility.Hidden;
}

Download the Windows Phone Toolkit and use the PhoneTextbox control.
