OnChangeEventHandler Delegate

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


Type: System.Object

The source of the event.

Type: System.Data.SqlClient.SqlNotificationEventArgs

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.
