TemplateControl.CommitTransaction Event
.NET Framework 3.0
Occurs when a transaction completes.
Namespace: System.Web.UI
Assembly: System.Web (in system.web.dll)
Assembly: System.Web (in system.web.dll)
'Declaration Public Event CommitTransaction As EventHandler 'Usage Dim instance As TemplateControl Dim handler As EventHandler AddHandler instance.CommitTransaction, handler
/** @event */ public void add_CommitTransaction (EventHandler value) /** @event */ public void remove_CommitTransaction (EventHandler value)
In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.
The following code example demonstrates how to register a custom event handler for the CommitTransaction event. 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.
