Noobie question: best way to maintain a list?

On an Asp.Net webpage, what's the best way to go about managing a list of
items?

When editing a library title I display a DataGrid of authors to which I'd
like to be able to add and remove. Ideally, I'd like to be able to work with
the list within a single page and not save the list until pressing an OK
button.

Should I keep a list of record IDs in a Session variable? Or postback the
list of IDs in the Request? Is there a way to hang onto a DataTable between
postbacks?

Thanks for any help,
Todd.

Database. SQL Express is one that is free.

You can store the datatable in ViewState or Session between clicks./

Yes, in ViewState. Be careful that you do not run into the native way
ViewState works, however, or you will delete records only to have them
reappear and visa/versa.
