OK, so I've scoured the forums here including the archives and I haven't come across a clear way to do dependent listboxes without refreshing the page. I need to call a list of categories based on a department listbox and can't figure out how to do it. I have a bunch of fields pre-filled from the URL data, but when the page refreshes after the department listbox is changed, I lose everything but the department listbox value. Yes, it works right but I lose all the other values on the form. If I can make this work right, that would be great, but I'd rather get around the refresh thing and get it to work without that altogether. I've read about the javascript arrays but that was way over my head and I'm hoping there is a better way or that someone can better explain it to me.
Thanks again for all your help... I really appreciate the comraderie on this forum.

the same way you send parameters for the listbox to change you need to resend all other paramters on the current page

Here's a good website with an ASP class to generate the Javascript for doing the dependent listboxes without a refresh. I think it's easy to setup and use.
http://www.atgconsulting.com/oodynlistbox.asp
Make sure you get the latest version of the class

I like those but I was never thrilled about sending all the data for each item in the dependant boxes. I like this one
better. but that is only my opinion.

I still can't get this to work... the atgconsulting website is good but puts things together piece by piece and I couldn't get it to work at all.
Does anyone had a CCS 2 file with this example in it? I'd really appreciate if I could take a look at a completed page in a CCS project.
Thanks,
Frank

Oooh, I like it!
I did a quick a diirty one myself.
http://www.gotodon.com/examples/dependentlistbox.asp. I decided to accept
the page refresh. Putting it in an external page is definitely clever and
gets around the limitations noted on my example. I suppose one could even
to it in a frame with no height (or width) and not have the popup (although
it's not all that annoying, and you COULD position it at -100,-100 or
something like that)

Hi Don...
It seems you are the expert in CCS, I hope you could help me with this...
I've tried to implement http://www.atgconsulting.com/oodynlistbox.asp but I
just cant get it to work, first because CCS use templates, that is .html and
..asp, where and how I have to put that code, and in the page it's all in
pieces...

Here's the approach I took:

I have not tried to implement the one from ATG Consulting, but it should be
without any tricks to it.

When it was all said and done and I had spent countless hours worrying about how to implement dependent listboxes into my application, I ended up using the codecharge FAQ method. It works ok for what I need it to do, but users have to make sure they select that box first or the rest gets cleared when the page refreshes.
The FAQ is at:

Here is an example of dependent list boxes. I like doing it this way but ... everyone has their own preference.

guys... most of the examples have only 2 listboxes... well i have four and i do not know what went wrong but for the third listbox, everything went crazy after changes occur... below is the code... pls help
function page_efi_reports1_ppu_name_OnChange()
{
var result;
window.location.href = "report.asp?ppu_name=" + this.value ;
return result;
}
function page_efi_reports1_substation_name_OnChange()
{
var result;
window.location.href = "report.asp?ppu_name=" + efi_reports1.ppu_name.value + "&substation_name=" + this.value;
return result;
}
function page_efi_reports1_feeder_code_OnChange()
{
var result;
window.location.href = "report.asp?ppu_name=" + efi_reports1.ppu_name.value + "&substation_name=" + efi_reports1.substation_name.value + "&feeder_code" + this.value;
return result;
}
the feeder_code listbox depends on the substation_name listbox, and the substation_name listbox depends on the ppu_name listbox... what did i do wrong?
