Visibility of combo box based off another without resubmitting form

[laakins]

I have a form within a table and it's been requested that if a certain selection is made from a combo box in the form then another combo box will become visible. The way the asp page is coded (by someone else prior) I'd prefer not to have to submit the form and display it again. I'm not sure if it's possible. My main background is in VB programming and I still consider myself a bit of a noob when it comes to asp. I've looked at the FAQ for this forum but as far as I can tell it only deals with data in one already visible drop down affecting data in another already visible drop down. Any help would be greatly appreciated. Thanks!

you can either use client side vbscript or an iframe, but in this case you would submit the form to another page embedded in the iframe; visually it looks like the user stays in the same page and it performs rather fast as usually the pages in the iframe contain very few elements.

in the latter case (client side VBScript), I only advise it if the combo box has very few options as you will have to hardcode them in the script.
in that case you could run something like the code below.
Assuming that your form is called form1 and your combo is called select1

<script language="VBScript">
sub hide_display_control

if document.form1.select1.value = "right choice" then
document.form1.othercontrolname.visible = true
end if


end sub



</script>

Life is what happens when you are making other plans.

I'd post this in the VBScript forum or the Javascipt forum.
