I got it figured out, the problem was that i was using server control. Using
<a href='attendance1.htm?albumid=<%=clickedalblum%>'>--some stuff--</a> Solved the problem. Thanks everyone for their response specially Ratna.

Do it from code behind in load event as

HyperLink1.NavigateUrl = "attendance1.aspx?albumid=" + clickedalbum;

ok do it as follows:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="test.aspx.cs" Inherits="test" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:HyperLink ID="HyperLink1" runat="server"  NavigateUrl='<%#clickedalbum %>' Text="Testlink"></asp:HyperLink>
</div>
</form>
</body>
</html>

In the code behind:

using System;

public partial class test : System.Web.UI.Page
{
 public string clickedalbum = "";
protected void Page_Load(object sender, EventArgs e)
{
     clickedalbum = "attendance1.aspx?albumid=123";
     DataBind();
}
}

do as avove, First copy paste whole code in a new page, then play with it. — Ratna, Apr 02 '13 at 11:38
