IDesignerHost.TransactionOpened Event

Adds an event handler for the TransactionOpened event.

Namespace:  System.ComponentModel.Design
Assembly:  System (in System.dll)

event EventHandler TransactionOpened

This event occurs when a transaction has begun.

A transaction can sometimes change multiple values. The transaction methods provide a way to prevent performance and flicker problems by avoiding repetitive processing. These methods defer processing until after the transaction has closed.
