You can try the following markup side code.

XML

<script type="text/javascript">
    function checkJavaScriptValidity()
    {
        document.getElementById("Enabled").style.visibility = 'visible';
        document.getElementById("Disabled").style.visibility = 'hidden';
    }
    </script>

Write the function within the head tag.
Now call the function from body onload. like the following:

<body onload="checkJavaScriptValidity()">

And Now create two div(within the form tag) to show the message on your browser.Please follow the code below:

XML

<div id="Enabled" style="visibility: hidden">
    Ya Browser JavaScript is enabled.have fun!!
</div>
<div id="Disabled">
    Browser JavaScript is disabled. Please Check the Browser Setting.
</div>

If you want to know that, the browser supports the javascript or not. You can use the following code:

C#

if (Request.Browser.JavaScript)
{
Response.Write("Javascript Enabled") ;
}
else
{
Response.Write("Javascript Disabled") ;
}

this is interisting,man. but i dont think the first code is neccesary where you can surrond the div "Disabled" with <noscript> tag.

Countered downvote. Looks good.

Agreed! 5+

In fact this is the only answer that deals with OP's question as Monjurul included code that can be used on the server side if the browswer supports JavaScript. OP asked specifically about checking in the web application which most certainly runs on the server side.
@Monjurul: Don't let that get you down though. Just keep up the good work and sooner or later you'll reap the benefits of your persistence. :thumbsup:

Thanks.I have checked both links and used this one in my application.
<noscript><meta http-equiv="refresh" content="0; url=whatyouwant.html"></noscript>

This one is also very good.
<noscript> <style type="text/css"> .pagecontainer {display:none;} </style> <div class="noscriptmsg"> You don't have javascript enabled. Good luck with that. </div> </noscript>

Good practical advice, my 5.
I added some explanation, please see. Trivial? Yes, very much. Still I feel for some it won't be immediately apparent form the first glance :-)

A bit of explanation to the Answer by Marcus: I may seem to be not really answering the question. Really, he did not provide the function IsJavascriptAllowed. But where such function should be called if it is not allowed? There is no such thing. So <noscript> is all you need.
