There is no built-in Recycle bin. Once you click "Delete" the object is delete from the memory and database immedetally.
You could create a custom table in the database and once a object is deleted, save all data to the database. This will
allow you to restore all deleted objects if necessary.
You could track when an item is being deleted by using the CommandName of Executed event of ContentManager(content items) or CmsManage(pages). You should add
your code in custom dll or inside Global.asax, Application_Start. This will ensure tha your code will be called every time.
