Hi, Try this
1. Bind your ListView with an
ObservableCollection<t></t>
in XAML or at runtime with the Listview property ItemSource
2. Load your Data From your database in this ObservableCollection object you created
3. After Deleting the the entity in your database you have 2 choice. fisrt delete the entity directly from your ObservableCollection object (better performance but will ingnore change made by other user if your application run in an network environnement ) or second Reload your Data From your database in then ObservableCollection object.
HOPE IT'S HELP
