I'm developing a new module and in my testing of it, I discovered that it doesn't delete the records from the database associated with when the module is deleted from a page.  Somehow, I thought that was automatic, but apparently it's not.  Is there an event I can tie into or some method that can be used to delete all the records associated with a module instance when it is dropped from a page? 

Thanks very much for any information.

After reading your post, I went back and looked at the Survey Module code and this is how they seem to try to handle the problem.  However, it doesn't work even in the Survey Module code.  The reason it appears not to work is because when you delete a module instance from a page, the module's record in the Modules table is not deleted.  It has an IsDeleted field that gets set to true.  So, the Foreign Key remains valid. 

Thanks for the response, but that doesn't seem to solve the problem.
