Fire logic when new object is saved

[Robert Lautenbach]

Is it possible to execute some custom logic whenever a particular new persisted object is saved?

For example, I have a bunch of persisted objects. One of them is a person object. Whenever I create and save a new person object I want to fire my custom logic to create some default related items for the new person.

It looks like I can add some event code to fire before a save occurs. But I don't see anyway to fire after a save.

Hi Robert Lautenbach,

You could use ITracking.Added event which occurs after an object was marked as persistent capable by the object context. The ITracking.Added event is being raised after the persistent object has been added to the IObjectContext:

…
scope.Tracking.Added += new AddEventHandler(Tracking_Added);
…

private static void Tracking_Added(object sender, AddEventArgs e)
{
 ClassName addedObject = e.PersistentObject as ClassName;
 if (addedObject!= null)
 {
  //retrieving of the addedObject’s ObjectId
  IObjectId objectId = Database.GetObjectId(addedObject);

  Console.WriteLine("{0}. {1}", objectId, addedObject.Name);
 }
}

I think that will help you.

Does this mean that's there's no way to link to this event from within the persistent class itself?

I basically want to have a PostStore event similar to PreStore so I can execute custom logic when a specific class is created and/or updated. Is there any way to accomplish this?

Hi Robert Lautenbach,

You could use the Database.GetContext method to obtain the IObjectContext instance which manages the given persistence capable object:

IObjectScope scope = Database.GetContext(this) as IObjectScope;

After that you could use the proposed approach from the preceding answer.
Hope that helps.
