    e As CustomSummaryEventArgs
)

Remarks

When creating a CustomSummaryEventHandler delegate, you identify the method that will handle the corresponding event. To associate an event with your event handler, add a delegate instance to this event. The event handler is called whenever the event occurs unless you remove the delegate.
