It’s obvious the error is on this line of code:

PaymentInfo payment = ((CreditCardInfo)Page).PaymentControl;

In your code, the PaymentControl belongs to Payment class.

  1. Replace CreditCardInfo with Payment.

Or

2. Check if a CreditCardInfo class has a property PaymentControl having PaymentInfo type.
