You're quite right, the scenario you described would be very inefficient.
But in the same sentence I assume those 50 - 60 items are reference data
(Countries, UOMs etc) and to hit the database to get a list of data like
that every time would in my eyes be expensive even for each user. A façade
or any other caching mechanism could hold those pieces of data to be
retrieved by the form when needs be.

Enough already, I have had a Stella and am ranting (Fired by today's drivel
OT conversations). I find the session forms annoying from my perspective as
I use them in a Wizard based approach (Back and Next) which handles creates
and updates so I have to be really careful about what I do and don't reset.
I would love a tag I could drop into my forms to copy properties to the next
request form without having to describe the underlying data, as suggested.
In fact I like this idea so much that I am going to crack on with it, I may
let you know how I get on if it is a worthy solution.

Tell me which is performance efficient & desired way:

Putting the form in session or making a trip to the
database..

assuming we have collection of 50 - 60 records..
