I have a class which inherits from BusinessBase . The constructor for this class includes a call to MarkAsChild( ).

I am attempting to perform some post-save logic by handling the Saved event:

Protected Sub OnObjectSaved(ByVal sender As Object, ByVal e As Csla.Core.SavedEventArgs) Handles Me.Saved

This event handler is never executing. I have found that this never executes for child objects. Is this by design? Is there another way to accomplish the same thing? Thanks.

Only Root objects have a Save method, all child objects are "saved" through the Root. That is probebly the reason why the OnObjectSaved event is not called on a child.

I see, but is anyone aware of any other way to include post-save processing for child objects that occurs on the client side of the DP functions?

That is, I cannot use Child_Insert, Child_Update, etc. because this processing may occur on the server side of the DP call.

You want this code to run on the client?

The only way I can see is to override Save() in the root class and have it recurse through the object graph, calling some post-processing method on each object. Or use a cascading method pattern like CSLA does with IsDirty, etc.

In any case, the trick is the override of Save(), and to do your client-side work after you call base.Save().

Oh, and make sure you use the result of the base.Save() call, because that'll be a different object graph than the one your override is living inside.
