In the MainWindow.xaml form, double‑click the Refresh button. This adds a click event method in the MainWindow.xaml.cs code file.
Add the following code to the btnRefresh_Click method.
private void btnRefresh_Click(object sender, RoutedEventArgs e)
{
lstCustomers.ItemsSource = bank.AllCustomers;
lstCustomers.DisplayMemberPath = "LastName";
}
Run the BankingApp application and then click the Refresh button.
If you have created Customer objects previously as part of the JADE developer's course, they are displayed.
