OnChangeEventHandler Delegate

Handles the OnChange event that is fired when a notification is received for any of the commands associated with a SqlDependency object.

Namespace: System.Data.SqlClient
Assembly: System.Data (in system.data.dll)

public delegate void OnChangeEventHandler (
	Object sender,
	SqlNotificationEventArgs e
)
/** @delegate */
public delegate void OnChangeEventHandler (
	Object sender, 
	SqlNotificationEventArgs e
)
Not applicable.

Parameters

sender

The source of the event.

e

A SqlNotificationEventArgs object that contains the event data.

The OnChange event does not necessarily imply a change in the data. Other circumstances, such as time-out expired and failure to set the notification request, also generate OnChange.
