ummmmm I see!
I gave it a look...
Add this to your addeditarticle code behind:
Protected Sub objCurrArticle_Inserted(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.ObjectDataSourceStatusEventArgs) _
You can do by your own the same on product page.
Find the objectdatasource that do the "product insert" and make a function like the one that I gave you for articles!
p.s. This only work for new articles inserted. If you want the same for article updated use the same code with the difference = ...objCurrArticle_Updated
feel free to post some doubt if you have some!
