Check Browsers Javascript on Code-Behind

 Hello,
        How do I know if my users browsers javascript is enabled/disabled on code-behind?

 I can check using inline statements like below but what about on code-behind?
...

<body onload="checkJavascript()">
function checkJavaScriptValidity() {
    document.getElementById("jsDisabled").style.visibility = 'hidden';
}
<span id="jsDisabled">disabled</span>
...
 
cheers,
imperialx
