I am working on a web page where I have 16 questions to be answered all with radio buttons. I need to set up the site so that for each question, if the user does not select an answer for a question in the list of radio buttons, I want a validation control to kick in and tell the user to please select an answer. How would I do that? Thanks!

Well, kinda but instead of using radiobuttonlsts I just use 2 radio buttons per question. 1 is yes and the other is no. Here is a look at my code in the control. If a person does not select either a yes or a no and they go to submit the form, i want a validation control to notify the person that the question has been left blank. Thanks!
Sure.
1. Create a style as follows in your css file:
.errordiv
{
background-color: #ffff99;
border: #ff0000 2px solid;
}
basically what it does is to add a red border around the group of radio buttons to alert user to select an answer.
2. Use the attached JavaScript function in your page. It is a complex function, but it will loop through all radio buttons for you automaticallly.
3. For your submit button, add OnClientClick="return validateForm()"
You are done.
Let me know if you have any trouble with the code.
Can I show you my back end code? Maybe this will help you help me with the Javascript. Basically for each question, if a person answers a question either yes or no, it stores a bit value which is eventually sent into the database. I will post it below:

When you say "list of radio buttons", do you mean the built-in ASP.NET RadioButtonList control?
