The implementation of the InvokeTransactedChange method notifies the design host, which is represented by serviceProvider, that a change is occurring to the specified member (property or method) of the associated control and, if the change is not canceled by the design host, invokes the specified callback using the specified context as the argument, and then notifies the design host that the change has completed.
If the design host or the associated control throws a static Canceled exception field of a CheckoutException exception, the transaction is canceled without invoking callback.
