body: <p>I have a user control called "TopMenu". I have five pages in my website. Menu codes are like that below:</p>
  
  <pre><code>&lt;%@ Control Language="C#" AutoEventWireup="true" CodeFile="UstMenu.ascx.cs"         Inherits="UstMenu" %&gt;
  &lt;ul class="tabs menu"&gt;
  &lt;li&gt;
  &lt;a href="Default.aspx" class="active"&gt;Anasayfa&lt;/a&gt;
  &lt;/li&gt;
  &lt;li&gt;
  &lt;a href="AboutUs.aspx"&gt;Hakkımızda&lt;/a&gt;
  &lt;/li&gt;enter code here
  &lt;li&gt;
  &lt;a href="Products.aspx"&gt;Ürünler&lt;/a&gt;
  &lt;/li&gt;
  &lt;li&gt;
  &lt;a href="Support.aspx"&gt;Destek&lt;/a&gt;
  &lt;/li&gt;
  &lt;li&gt;
  &lt;a href="Contact.aspx"&gt;İletişim&lt;/a&gt;
  &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>I have an "active" class as you see upthere in my css.For example, If a user click on support page, Support page link must take "active" class. I dont want to write my menu to all of my pages.    How can i detect which page i am in?</p>
