Property Value

A NotificationComputedFieldCollection object that represents the collection of noncomputed fields for the notification class.

Remarks

Notification fields define notification data storage for a notification class. The subscription rule that generates notifications inserts notification values into these fields.

Each notification class must have at least one NotificationField in a NotificationFieldCollection.

Example

The following examples show how to use the NotificationFieldCollection to add notification fields to 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)

You can add fields at a specific position:

// Define a Price field and add it at position 1 in the collection
NotificationField notificationPrice = 
    new NotificationField(flightNotifications, "Price");
notificationPrice.Type = "float";
flightNotifications.NotificationFields.Add(notificationPrice, 1);

' Define a Price field and add it at position 1 
' in the collection.
Dim notificationPrice As NotificationField = _
    New NotificationField(flightNotifications, "Price")
notificationPrice.Type = "float"
flightNotifications.NotificationFields.Add( _
    notificationPrice, 1)

You also can add fields before a specific notification field:

// Define a GoingTo field and add it before the Price field
NotificationField notificationDestination = 
    new NotificationField(flightNotifications, "GoingTo");
notificationDestination.Type = "nvarchar(6)";
flightNotifications.NotificationFields.Add(
    notificationDestination, "Price");

' Define a GoingTo field and add it before the Price field.
Dim notificationDestination As NotificationField = _
    New NotificationField(flightNotifications, "GoingTo")
notificationDestination.Type = "nvarchar(6)"
flightNotifications.NotificationFields.Add( _
    notificationDestination, "Price")
