use this code ref from ASp.net Form site

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>Untitled Page</title>

<script type="text/javascript">


function ReceiveServerData(arg, context)
{
//alert(arg);
}

function getValues()
{
var name='john';
CallTheServer(name, '');


}
</script>

</head>
<body >
<form id="form1" runat="server">
<div>

<input id="btnSubmit" type="button" value="Submit" onclick="getValues();" />

</div>
</form>
</body>
</html>





In C# Code Behind



using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class Default7 : System.Web.UI.Page, System.Web.UI.ICallbackEventHandler
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{

string cbReference = Page.ClientScript.GetCallbackEventReference(this, "arg", "ReceiveServerData", "context");
string callbackScript = "function CallTheServer(arg, context) {" + cbReference + "; }";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "CallTheServer", callbackScript, true);
}
}


public string GetCallbackResult()
{
return "";
}


public void RaiseCallbackEvent(string eventArgument)
{
//In this POint U will get Value john in eventArgument
}



}
