Highlight Selected Tab in ASP.Net Menu

Question

I am trying to hightlight with different color the selected tab in ASP.NET menu. It seems simple to do this but first I am not able to make it to work, and second I cannot find a good working example so far.

ASP/HTML

<div class="clear hideSkiplink">
                <asp:Menu ID="NavigationMenu" runat="server" CssClass="menu" EnableViewState="False"
                    IncludeStyleBlock="false" Orientation="Horizontal">

                    <Items>
                        <asp:MenuItem NavigateUrl="~/ReadMe.aspx" Text="Read Me" />
                        <asp:MenuItem NavigateUrl="~/Summary.aspx" Text="Summary" />
                        <asp:MenuItem NavigateUrl="~/Detail.aspx" Text="Detail" />
                    </Items>
                </asp:Menu>
  </div>

CSS

div.hideSkiplink
{
    background-color:#3a4f63;
    width:100%;
}

div.menu
{
    padding: 4px 0px 4px 8px;
}

div.menu ul
{
    list-style: none;
    margin: 0px;
    padding: 0px;
    width: auto;

}

div.menu ul li a, div.menu ul li a:visited
{
    background-color: #465c71;
    border: 1px #4e667d solid;
    color: #dde4ec;
    display: block;
    line-height: 1.35em;
    padding: 4px 20px;
    text-decoration: none;
    white-space: nowrap;
}

div.menu ul li a:hover
{
    background-color: #bfcbd6;
    color: #465c71;
    text-decoration: none;
}

div.menu ul li a:active
{
    background-color: #465c71;

    color: #cfdbe6;
    text-decoration: none;
}

This is a Working solution: *Script*

<script language="javascript" type="text/javascript">

   $(function () {
        // this will get the full URL at the address bar
        var url = window.location.href;

        // passes on every "a" tag 
        $("#cssmenu a").each(function () {
            // checks if its the same on the address bar
            if (url == (this.href)) {
                $(this).closest("li").addClass("active");
            }
        });
        $("#header a").each(function () {
            // checks if its the same on the address bar
            if (url == (this.href)) {
                $(this).closest("li").addClass("active");
            }
        });

    });
</script>

Markup

List items with div id ="cssmenu"

<div id='cssmenu'>
    <ul>
       <li><a href="../Admin/dashboard.aspx"><span>Dashboard</span></a></li>
       <li><a href="../Admin/Report.aspx"><span>Reports</span></a></li>
       <li><a href="../Admin/Shop.aspx"><span>Shop</span></a></li>
       <li><a href="../Admin/system.aspx"><span>System</span></a></li>
    </ul>
</div>
