How make toast notification keep display until user click on it?

Question

I am using the Microsoft.Toolkit.Uwp.Notifications package to display toast notification on my WPF project in windows10

I found that the toast will only shows for 6-7 seconds and then disappears, I want him keep display until user interact on it, I try this:

            var builder = new ToastContentBuilder()
                .AddArgument("Action", "NewToast")
                .AddArgument("ActionData", url);

//The documentation says set scenario to "reminder" will keep the toast display, but not work at all..
//And the "ExpirationTime" property is also not working...
            builder.SetToastScenario(ToastScenario.Reminder);
            builder.AddText(sFrom + " " + date.Substring(11, 5) + " " + windowTitle)
            .AddText(title)
            .AddText(idea)
            .Show(toast =>
            {
                toast.ExpirationTime = DateTime.Now.AddHours(8);
            });

So what's the right way to keep it display?

@aluzi liu , Welcome to Microsoft Q&A, based on my test, I reproduced your problem when using ToastScenario.Reminder.

There are two methods to let toast notification keep display until user click on it.

First method, we need to add a button to the ToastContentBuilder, like the following code:

 var builder = new ToastContentBuilder()
               .AddArgument("Action", "NewToast")
               .AddArgument("ActionData", "");

            //The documentation says set scenario to "reminder" will keep the toast display, but not work at all..
            //And the "ExpirationTime" property is also not working...
            builder.SetToastScenario(ToastScenario.Reminder);
  
            builder.AddText("2023-03-08")
            .AddText("test1")
             .AddButton(new ToastButton()
        .SetContent("Text reply"))
            .AddText("My Idead")
            .Show();

You could refer to the Microsoft Learning Reminders, which has the following description:

You must provide at least one button on your app notification. Otherwise, the notification will be treated as a normal notification.

Therefore, we have to add a button in the ToastContentBuilder.

Second method, you could also useToastScenario.IncomingCall directly without adding the button.

Please try the following code:

 builder.SetToastScenario(ToastScenario.IncomingCall);

Based on my test, after I used the above two methods, the toast notification will keep displaying until you click it.

Hope my solution could help you.

Best Regards,

Jack
