NOTE: This API is now obsolete.
Gets or sets an arbitrary string for use by a Windows SharePoint Services 2.0 event handler for document library events.
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
The EventSinkData property only applies to a document library or to a list derived from a document library and contains the data that is specified in the user interface when the event handler is bound to the list. This property returns a NotSupportedException exception if the list is neither a document library nor a list derived from a document library.
For more information about this property and about document library events, see Walkthrough: Handling Document Library Events.
