I'm creating a messaging/bulletin board system that primarily consists
of two frames - a listing of messages at the top and a message
viewer/editor at the bottom.

I have already created a working model using code behind and now want
to convert it over to being a control and would be interested to know
the views of the panel here.

1. Firstly, can a single control being used on both the pages pass
variables behind the scenes other than using session variables? (I
suspect it can't, but it's worth asking.)

2. If the answer to 1 above is no, would it be best to create a single
control or two different controls for the top and bottom pages?

I would appreciate you views.

You're correct in assuming that it's not possible to pass information
directly between pages/frames. You have to use one of the state objects
or pass variables through the querystring. I personally find the
querystring method to be most useful.

As for creating one or two controls... There's no sense in creating two
different controls if they both have the exact same functionality and in
such a case you would benefit more from creating only one. If they both
contain SOME similar functionality, you might do best to create two
controls and derive them both from a base class that you should also
create. And, of course, if both controls are completely different, two
controls is definitely the way to go.

My $.02...
I've removed all of my framesets in my consulting home site with
top/bottom user controls (http://www.sharkcode.com).

1. The issues associated with passing variables between pages are the
same regardless of the controls. You still need to use things like
Session variables or, in some cases the Viewstate. There is one thing to
remember with the controls that is very handy -- you can pass values
into them from the HTML attributes as long as you define public
properties in the control.

2. I would guess that two controls (top/bottom) would be more flexible,
and make the coding of each page clearer.
