How to get Resulting Objects before they are Persisted to database?

Hi Experts,

     I am trying to get resulting Objects added to the change task before they are persisted to the database, as I am trying to put a constraint on the resulting object. I want only the resulting object having design view to be permitted and if other parts are added it should not allow him to create the change notice. So is there a way I can get the resulting object before they are persisted.
