Remarks

Handle the UpdateToastContent event to customize a notification’s content. To specify the content markup in code, use facilities provided in the System.XML namespace. To learn more about the content schema, see Toast Content Schema.

C#

using System.Xml;

 public Form1() {
     InitializeComponent();
     //...
     toastNotificationsManager1.UpdateToastContent += ToastNotificationsManager1_UpdateToastContent;    
 }

 private void ToastNotificationsManager1_UpdateToastContent(object sender, DevExpress.XtraBars.ToastNotifications.UpdateToastContentEventArgs e) {
     XmlDocument content = e.ToastContent;
     XmlNode bindingNode = content.GetElementsByTagName("binding").FirstOrDefault();
     XmlElement group = content.CreateElement("group");
     bindingNode.AppendChild(group);

     //Create the first subgroup and add it to the root group.
     XmlElement subGroup = content.CreateElement("subgroup");
     group.AppendChild(subGroup);

     //Create the subgroup's first caption ("subgroup1").
     XmlElement text = content.CreateElement("text");
     subGroup.AppendChild(text);
     text.SetAttribute("hint-style", "base");
     text.InnerText = "subgroup1";

     //Create the subgroup's second caption ("captionSubtle").
     text = content.CreateElement("text");
     subGroup.AppendChild(text);
     text.SetAttribute("hint-style", "captionSubtle");
     text.InnerText = "captionSubtle";

     //Create the second subgroup and add it to the root group.
     subGroup = content.CreateElement("subgroup");
     group.AppendChild(subGroup);

     //Create the subgroup's first caption ("subgroup2").
     text = content.CreateElement("text");
     subGroup.AppendChild(text);
     text.SetAttribute("hint-style", "captionSubtle");
     text.SetAttribute("hint-align", "right");
     text.InnerText = "subgroup2";

     //Create the subgroup's second caption ("captionSubtle").
     text = content.CreateElement("text");
     subGroup.AppendChild(text);
     text.SetAttribute("hint-style", "captionSubtle");
     text.SetAttribute("hint-align", "right");
     text.InnerText = "captionSubtle";

     //Save the toast markup as an XML file for debugging purposes
     content.Save(@"D:\Toast.xml");
 }
