How to delete row in sqlite via ListView in C# for windows 8 app

Here is the code i am using. The item in ListView AllEventsList in table Events does not gets deleted.

private async void DeleteSelected(object sender, RoutedEventArgs e)
    {
        try
        {
            var dbpath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "data.db3");
            using (var db = new SQLite.SQLiteConnection(dbpath))
            {

                db.Delete<Events>(AllEventsList.SelectedItem.ToString());//selected item



                var d = from x in db.Table<Events>() select x;
                AllEventsList.Items.Clear();
                foreach (var sd in d)
                {
                    AllEventsList.Items.Add(sd.EventName.ToString());
                }

                db.Dispose();
                db.Close();  
            }
            var line = new MessageDialog("Selected Item Deleted");
            await line.ShowAsync();
        }
        catch
        {
        }
    }

while this works:

  db.DeleteAll<Events>();
