 <p>I found the answer to your question due to @Squidward. From the above article I went to <a href="https://msdn.microsoft.com/ru-ru/library/windows/apps/xaml/hh868212.aspx" rel="nofollow">https://msdn.microsoft.com/ru-ru/library/windows/apps/xaml/hh868212.aspx</a></p> <p>In my code I added the following and my OnLanched field in the Arguments data. Now I might be able to make plans!</p> <pre><code> ToastTemplateType _toastTemplate = ToastTemplateType.ToastText02; XmlDocument _toastXml = ToastNotificationManager.GetTemplateContent(_toastTemplate); //this set argument for OnLaunched IXmlNode toastNode = _toastXml.SelectSingleNode("/toast"); ((XmlElement)toastNode).SetAttribute("launch", "111111"); //--- </code></pre>
