Raises the AbortTransaction event.

The following code example demonstrates how to use the and OnCommitTransaction methods. Because TemplateControl is an abstract class, this code example uses the Page class, which is derived from the TemplateControl class. Account is a class that supports a Debit operation, which is transactional and must execute as a unit. If any exception is raised during this operation, the transaction is ended.
