The SPEventPropertiesBase class is not instantiated but provides methods for classes deriving from it that are listed in the Inheritance Hierarchy section below.


The following example of an event handler method overrides the ItemDeleting() method and uses inherited properties of the SPEventPropertiesBase class to cancel an event and display an error message.

public override void ItemDeleting(SPItemEventProperties properties)
    properties.Status = SPEventReceiverStatus.CancelWithError;
    properties.ErrorMessage = "Deleting items is not supported.";
Public Overrides Sub ItemDeleting(ByVal properties As SPItemEventProperties)
    properties.Status = SPEventReceiverStatus.CancelWithError
    properties.ErrorMessage = "Deleting items is not supported."
End Sub
