屬性值
true if the field is used to determine digest grouping; otherwise, false.
備註
The DigestGrouping property is optional, and the default value is false.
If you want a field used to determine if notifications should be grouped when using digest delivery, set DigestGrouping to true. For example, if a flight application sends notifications for multiple carriers, you can set DigestGrouping to true on the Carrier field so that the notifications for a carrier are grouped into a single notification.
If you are using digest delivery but you do not set DigestGrouping to true on any fields, Notification Services groups messages within a notification batch that have the same SubscriberId, DeviceName, and SubscriberLocale values.
If you add, delete, or update a DigestGrouping element, updating the application deletes and re-creates the notification class to which it corresponds. This includes dropping and re-creating the SQL Server tables used by this notification class.
範例
The following examples show how to define a notification field that is used to group digest notifications, and then add the field to the collection of notification fields for a notification class:
// Define a LeavingFrom notification field and use it for grouping
// digest messages. Add it to the end of the field collection
NotificationField notificationOrgin =
new NotificationField(flightNotifications, "LeavingFrom");
notificationOrgin.Type = "nvarchar(6)";
notificationOrgin.DigestGrouping = true;
flightNotifications.NotificationFields.Add(notificationOrgin);
' Define a LeavingFrom field and use it for grouping
' digest messages. Add it to the end of the collection.
Dim notificationOrgin As NotificationField = _
New NotificationField(flightNotifications, "LeavingFrom")
notificationOrgin.Type = "nvarchar(6)"
notificationOrgin.DigestGrouping = True
flightNotifications.NotificationFields.Add(notificationOrgin)
