OnChangeEventHandler Delegate

Other Versions

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)

Syntax

C++

public delegate void OnChangeEventHandler(
	Object^ sender,
	SqlNotificationEventArgs^ e
)

Parameters

sender: Type: System::Object^
The source of the event.

e: Type: System.Data.SqlClient::SqlNotificationEventArgs^

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.
