How can I add WaterMark property to PasswordBox in Winrt?

I need WatermarkPasswordBox control but there is not in Winrt. Maybe we can add Watermark property to PasswordBox. Are there anyone who can do it?

Thanks

UPDATE 1

If you don't want to use 3rd party DLL, add these two methods in PasswordBoxBehavior.cs file.

using System.Reflection;

public static T FindVisualChildByName<T>(this DependencyObject fe, string name) where T : DependencyObject
{
    if (string.IsNullOrEmpty(name))
    {
        throw new ArgumentNullException("name");
    }
    for (int i = 0; i < VisualTreeHelper.GetChildrenCount(fe); i++)
    {
        DependencyObject child = VisualTreeHelper.GetChild(fe, i);
        string a = child.GetValue(FrameworkElement.NameProperty) as string;
        if (a == name)
        {
            return child as T;
        }
        T t = FindVisualChildByName<T>(child, name);
        if (t != null)
        {
            return t;
        }
    }
    return default(T);
}

public static T FindVisualParent<T>(this DependencyObject fe) where T : DependencyObject
{
    for (fe = VisualTreeHelper.GetParent(fe); fe != null; fe = VisualTreeHelper.GetParent(fe))
    {
        T t = fe as T;
        if (t != null)
        {
            return t;
        }
    }
    return default(T);
}
