Hello Rishi,
For the radiobuttonlist,you can iterate through all the conrols, and pass the ClientId property to a javascript function.
You basically create the javascript in a string in the codebehind, and in this string, you keep adding the clientid of each radio button.
Once that string is ready, you can add it to the page. The string you create will have the function, which does the validation
the function contains all the radio buttons to check for.
