protected override IList<SubscriptionInformation> ReadData(
	int dataIndex
)

Protected Overrides Function ReadData ( 
	dataIndex As Integer
) As IList(Of SubscriptionInformation)

Parameters

dataIndex

Type: SystemInt32
When data to read is paged this is the index if the data page to read. This first data page is zero the event handler increments this value for each subsequent calls.

Return Value

The event handler calls this method when it reads subscribers to send mail to. This method gets called until the returned collection is either null or empty.

Note
Important When you implement this method you must make sure to return an empty collection of data when there is no more data to return. Even if there is only one record returned the event handler will call this method again with the next dataIndex!
