you can use javascript function something like this..
function yourfunction(radioBtnListID)
{
var rdbtnlist = document.getElementId(radioBtnListID);
for(var i=0;i<rdbtnlist.options.length-1;i++)>
{
if (rdbtnlist.options[i].checked==true)
{
var name = rdbtnlist.options[i].name;
alert("item " + name + " is checked");
}
else
{
var name = rdbtnlist.options[i].name;
alert("item " + name + " is checked");
}
}
}
hope this helps...
