In ImageGear for Silverlight TWAIN, when acquisition is canceled in an event, no exception is thrown. This is different from ImageGear .NET TWAIN, where an ImGearException is thrown with the error code TWAIN_OPERATION_CANCELED_BY_EVENT. For more information about how acquisition can be canceled by an event, see the BeforePage and AfterPage events and the associated event arguments ImGearTWAINBeforePageEventArgs and ImGearTWAINAfterPageEventArgs, respectively.
