Can you elaborate "Now on click of Button I want to find all the radio button elements" ? Using jquery/javascript or in the action method?

you can easily find all radio buttons using jquery:

JavaScript

$('input[type="radio"]').each();

So if you want to do something with your radiobuttons after clicking a button then:

ASP.NET

<asp:button id="myButton" runat="server" onclientclick="doSomWork()" />

JavaScript

<script type="text/javascript">
function doSomeWork(){
  $('input[type="radio"]').each(function(){
     // iterates all radio buttons
     var radioButton = $(this)
     // do something with the current radiobutton...
  });
}
</script>

The easiest way to implement jquery is to add this script reference in your head section:

HTML

<link rel="stylesheet" type="text/css" href="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" />
