WPF Notification (Desktop Alert, Toast)

Notifications.Wpf paketini kullanarak notification paketi kullanımının yönergeleri ve örnek proje  aşağıda ki adreste yer alıyor.

https://github.com/Federerer/Notifications.Wpf


Burada MVVM modeli için güzel bir örnek var. Ben MVVM kullanmadan standart özelleştirilmiş bir notification yapımını göstereceğim.

1. Notifications.Wpf paketini projemize nuget ile ekleyelim.

2. NotificationView adında bir User Control ekleyelim.

3. NotificationView.xaml içerisine aşağıdaki xmlns ekleyelim.

xmlns:controls="clr-namespace:Notifications.Wpf.Controls;assembly=Notifications.Wpf"

Ayrıca notification kapatmak için button içerisine  controls:Notification.CloseOnClick="True"
property eklendi. Yani bu butona basıldığı zaman Notification kapatılacak.

4. NotificationView.cs içerisine aşağıdaki kodları ekleyin
     
        private readonly INotificationManager _manager;
        public string Title { get; set; }
        public string Message { get; set; }


        public NotificationView(INotificationManager manager)
        {
            InitializeComponent();
             _manager = manager;

        }

5. Açmak için is MainWindows içerisinde aşağıdaki NotifcationManager tanımlayalım.

private NotificationManager notificationManager;

MainControl() constructor içerisinde notificationManager'ın bir örneğini oluşturalım

notificationManager = new NotificationManager();


Daha sonra notification ile göstermek için

 var content = new NotificationView(notificationManager);

ile gösterilecek notification oluşturulur.

notificationManager.Show(content, expirationTime: TimeSpan.FromSeconds(30));

metodu ile gösterilir.
