Reading dropdown values in ASP

[Martin Walke]

Hi all,

I have an ASP application where I need to not only read the selected item
from a combo box on a web page but also all the options in the combo box.
Can someone point me in the right direction.

I can obviously use request.querystring() or request.form() to get the
selected value but not sure about how to get the options.

TIA
Martin

Obviously, you have to store the values somewhere that is accessible to the
code running on the web server. Possibilities inclued a database, a text
file, an xml file, a session variable, an application variable, or some
combination of the above.

Oh! One possibility i neglected to mention was to use a hidden field in
the form to store the option values, making them part of the Request.

You can't. When the form is submitted, one value is transmitted for a
select group: the "value" attribute of the selected option. Nothing
else is sent.

If you want to know the other options in the select group, you'll have
to do it another way: store them in a database, in the session object,
something like that. And bear in mind, that what's transmitted for the
selected option is not what the user sees, it's the "value" attribute.

Thanks Bob.

My line of thinking was to a hidden field anyway.

I just wondered, although couldn't find any reference to it, whether the
srever could access the data in some sneaky way. Obviously, if I'd thought
it through, that client side data doesn't get transmitted in the Request.

Thanks Tim. It was as I assumed. As per my comment to Bob, I'll use a hidden
field populated by my validate routine.
