How do I show specific data in a form on ASP page if Radio Button has value of "checked" ?

Can someone show me how to do this? I have used a checkbox to show certain data if the box is checked and if the box isn't checked, it doesn't show the data. My only problem with that is this: the checkbox as a submit function that posts back to itself on the same page. I don't want to do that. I don't want the page to refresh because I don't want to lose the data if the user has typed anything in the form.





Something like what I'm trying to do is:


1. Have a form on an ASP page with 3 sections


Section A - Table with fields for Personal Information


Section B - Table with fields for Contact Information


Section C - Table with fields for Company Information


2. Before Section C I would like a Radio Group with 2 Options "Yes" and "No". If the user would like to register as a company they would click "Yes".


3. When the user clicks "Yes", the fields in Section C will no longer be greyed out and the user will be able to fill them in.





Much thanks to you guys!

I'd use javascript and html


%26lt;body%26gt;


%26lt;div id='SectionA'%26gt;


personal information table goes here


%26lt;/div%26gt;


%26lt;div id='SectionB'%26gt;


contact information table goes here


%26lt;/div%26gt;


%26lt;input type='checkbox' id='chkCompany'


onclick='javascript:togglecompany(this...


text='Register as company'%26gt;


%26lt;div id='SectionC' style='visibility:hidden;'%26gt;


company information table goes here


%26lt;/div%26gt;


%26lt;/body%26gt;





%26lt;script language='javascript'%26gt;


function togglecompany(thecheckbox){


if(thecheckbox.value==true){


document.getElementById


('SectionC').


style.visibility='visible';


//the above 3 lines should be 1


}


else{


document.getElementById


('SectionC').


style.visibility='hidden';


//the above 3 lines should be 1


}


}





%26lt;/script%26gt;





if the user checks "register as company"


then the company information appears,


otherwise it remains hidden.
