Using
http://www.4guysfromrolla.com/webtech/071101-1.shtml
example, I have a list of resources from a MSAccess database.  When the
user selects one of the items in the listbox, I would like him/her to be
automatically redirected to a page that describes the resource s/he
chose from the list.

I did this with a hard coded listbox in
http://adams.dom.washington.edu/resources/index.html
and a little javascript to redirect onchange.

But how to accomplish the same thing in asp.net?  I do not want the user
to have to make an extra key click by adding a submit button.

Thanks.

assuming your listbox has an ID="lb"

C#

on page load, or on control load, add this:

this.lb.Attributes.Add("onchange", "name_of_javascript_function_here");

now when the selection is changed by the user, the javascript function will 
get fired to redirect the user to the new page.  you can probably reuse the 
existing javascript function you already have written.

make sense?

Sorry I'm new at this, take a look at 
http://adams.dom.washington.edu/resources/tindex.aspx
and you will see my javascript function (that worked with the static
page http://adams.dom.washington.edu/resources/index.html)
Also you will see how asp.net translated my <asp:listbox...> to a html
<select...> where I have included the onchange action. I used vb.net to
fill the listbox according to the sample by scott mitchell at 4guys. How
should I change my code so the onchange action will fire the javascript
function "redir2aspx"?
thanks again.

this.lb.Attributes.Add("onchange", "redir2aspx()");
