provides a way for calling code to identify a particular EditOperation within a subsequent EditEvent. Setting an EventToken in an EditOperation is optional - by default it is null. If set to a non-null object, the EditOperation is subsequently successful, and, an EditEvent is published, then the EventToken object set here, will be available from the corresponding ArcGIS.Desktop.Editing.Events.EditCompletedEventArgs.EventToken.

public object EventToken {get; set;}
