Solution 1

for your radio buttons, set their onclick property to countUp(). Then use a javascript function to update a counter and show its value in an element. like this :

<input type="radio" name="a" value="a" checked=""  önclick="CountUp()">a</input>
<input type="radio" name="b" value="b"  önclick="CountUp()">b</input>

<div id="result">0</div>

JavaScript

<script type="text/javascript">
var counter = 0;

function countUp() {
    counter++;
    document.getElementById("result").innerHTML = counter;
}
</script>

but I use radiobuttonlist item I didnt use radiobutton

radiobuttonlist not has onclick even

there is no radiobuttonlist element in html. every radiobuttonlist generates html code like above. if you are doing it with ASP.NET, like c#, you need to set each generated radiobutton's onclick attribute. something like this :

foreach(ListItem RadioButton in RadioButtons){
RadioButton.Attributes.Add("onclick", "countUp();");
}

In each of the input type="radio" ... objects that are in your html you will have an onclick handler that will hit a javascript method similar to what The Zetta has shown above.
In that onclick handler you will have to loop through the DOM objects and count the number of radio items that are checked and then set the resulting value to the appropriate label that is to show the value
