Valeur de propriété

true if the computed field is used to determine digest grouping; otherwise, false.

Notes

The DigestGrouping property is optional, and the default value is false.

If you want a computed field used to determine if notifications should be grouped when using digest delivery, set DigestGrouping to true. For example, if a calendar application notifies users of future events, you can set DigestGrouping to true on a computed DaysToEvent field so that only notifications for events on the same day 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 Microsoft SQL Server tables used by this notification class.

Exemple

The following examples show how to set the DigestGrouping property when using the default constructor:

NotificationComputedField computedPrice = 
    new NotificationComputedField();
computedPrice.Name = "FormattedPrice";
computedPrice.Parent = flightNotifications;
computedPrice.DigestGrouping = false;
computedPrice.SqlExpression = "CONVERT(NVARCHAR(10), Price, 1)";
flightNotifications.NotificationComputedFields.Add(computedPrice);

Dim computedPrice As NotificationComputedField = _
    New NotificationComputedField()
computedPrice.Name = "FormattedPrice"
computedPrice.Parent = flightNotifications
computedPrice.DigestGrouping = False
computedPrice.SqlExpression = "CONVERT(NVARCHAR(10), Price, 1)"
flightNotifications.NotificationComputedFields.Add(computedPrice)
