Hi folks!

I have a (perhaps simple) question about collections. I have read past threads, and NHibernate documentation, but unsure of what is the best way to proceed. Any pointers would be greatly appreciated.

Scenario:

Basically, I have a collection that is ordered by the user. The default order should be the order, in which the user added items to the collection. But, then, user should have a ability to change the order based on his wishes. (Think of NetFlix.com’s movie queue).

Thanks in advance!

You just need to implement a list with a sequence. Then use the sequence to control the order. Basically the sequence will be managed for you by NHibernate. The sequence will be determined by the order of the items in the list.

So if a user moves an item from index 5 to say index 3, your code would remove the element from index 5 and insert it into index 3.

Previously I have created wrapper classes that expose a Move operation that will handle all the internals for you and the caller only has to know that they should execute the Move operation.

Hi Jnapier,

Could you share some code that you are talking about?

Thanks,
Desiguy
