    private void UpdateToast(string style, string value)
        ToastTemplateType template = (ToastTemplateType)Enum.Parse(typeof(ToastTemplateType), style);
        XmlDocument toast = ToastNotificationManager.GetTemplateContent(template);
        XmlNodeList text = toast.GetElementsByTagName("text");
