You are developing a Windows Presentation Foundation (WPF) application. You add a TextBox control to the design surface and bind it to an underlying window resource named dsGiftCertificate. The control uses the binding XAML as follows.

  validation and error message.
• B.Update the binding source as follows.
  <Binding Source="{StaticResource dsGiftCertificate}"
  UpdateSourceTrigger="Explicit" Path="Coupon"
  ValidatesOnDataErrors="True" />
• C.Implement the IDataErrorlnfo interface. Use the indexer for the custom validation and
  error message.
