Updating Sort Order
I have a User Interface where user can update the SortOrdr of any products or he can add a new product and can give a user defined sort order.Multiple products can be added and sortorder field is optional. I need to persist the sort order in the database after the user clicks save.So I have listed different scenarios on how sort oder should be updated.I need to write a stable sort or some logic to make sort order unique while persisting.Can you guys tell me where should I start?
