IDesignerHost.TransactionOpening Event

Adds an event handler for the TransactionOpening event.

[Visual Basic]
Event TransactionOpening As EventHandler
event EventHandler TransactionOpening;
__event EventHandler* TransactionOpening;

[JScript] In JScript, you can handle the events defined by a class, but you cannot define your own.

Event Data

The event handler receives an argument of type EventArgs.


This event occurs when a transaction is about to begin.

This method allows designer host clients to perform operations before other handlers are notified that a transaction has begun. The specified handler is called only when the first call to CreateTransaction is made. Subsequent calls do not generate this event until all transaction objects have been disposed.


Platforms: Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
