windows 8 metro app - toast notification - notifications

Question

I am developing a Windows 8 metro-style application using toast notification. (C# + xaml combination)
I looked into MS metro style sample code and tried to apply it to my project,
looks like I used the code exactly the same way, but I don't know why it is not working..
(There is no error, it builds successfully but just doesn't work.)
What I'm trying to do is very simple:
There is a button.
When the button_click event occurs, I'd like to pop a toast notification.
This is what I did:
namespace Application1
{
public sealed partial class BlankPage : Page
{
public BlankPage()
{
this.InitializeComponent();
Scenario2Init();
}
void Scenario2Init()
{
toastTest.Click += (sender, e) => { ToastAlarm(true); };
}
void ToastAlarm(bool loopAudio)
{
XmlDocument toastXml = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastText02);
// Toasts can optionally be set to long duration by adding the 'duration' attribute
IXmlNode toastNode = toastXml.SelectSingleNode("/toast");
((XmlElement)toastNode).SetAttribute("duration", "long");
// This XmlNodeList will have two items since the template we are using has two text fields.
XmlNodeList stringElements = toastXml.GetElementsByTagName("text");
stringElements.Item(0).AppendChild(toastXml.CreateTextNode("Long Duration Toast"));
XmlElement audioElement = toastXml.CreateElement("audio");
if (loopAudio)
{
// Long-duration Toasts can optionally loop audio using the 'loop' attribute
audioElement.SetAttribute("src", "ms-winsoundevent:Notification.Looping.Alarm");
audioElement.SetAttribute("loop", "true");
stringElements.Item(1).AppendChild(toastXml.CreateTextNode("Looping audio"));
}
else
{
audioElement.SetAttribute("src", "ms-winsoundevent:Notification.IM");
}
toastNode.AppendChild(audioElement);
ToastNotification toast = new ToastNotification(toastXml);
ToastNotificationManager.CreateToastNotifier().Show(toast);
//Scenario2OutputText.Text = toastXml.GetXml();
}
}
}
If I click the button, nothing happens. Why?

Answer 1

Your code looks correct to me; I don't have Win8 with me here right now so I can't test it. However, you may want to check your app's manifest if you enabled Toast or not in the "Toast Capable" field in VS. Hope this helps.

Answer 2

Did you enable "Toast capable" in Package.appxmanifest?

Answer 3

I think, there are two reasons,
First may be relating to toast capability of your application. For this set ToastCapable="true" in your Package.appxmanifest
Second one is run application in Local Machine rather than Simulator. I found that Simulator is not able to produce Toast notification.

Answer 4

i think you can just use Xml String
// Create the toast content by direct string manipulation.
// See the Toasts SDK Sample for other ways of generating toasts.
string toastXmlString =
"<toast duration=\"long\">\n" +
"<visual>\n" +
"<binding template=\"ToastText02\">\n" +
"<text id=\"1\">Alarms Notifications SDK Sample App</text>\n" +
"<text id=\"2\">" + alarmName + "</text>\n" +
"</binding>\n" +
"</visual>\n" +
"<commands scenario=\"alarm\">\n" +
"<command id=\"snooze\"/>\n" +
"<command id=\"dismiss\"/>\n" +
"</commands>\n" +
"<audio src=\"ms-winsoundevent:Notification.Looping.Alarm5\" loop=\"true\" />\n" +
"</toast>\n";
