<%@ Master Language="C#" AutoEventWireup="true" EnableViewState="true"  CodeFile="master.master.cs" Inherits="master" %>
 
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp"%>
<!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 id="Head1" runat="server">
        <meta charset="utf-8"/>
        <meta http-equiv="X-UA-Compatible" content="IE=9" />
        <meta http-equiv="X-UA-Compatible" content="IE=7" />
        <meta http-equiv="X-UA-Compatible" content="IE=8" />
        <meta http-equiv="X-UA-Compatible" content="IE=10" />
        <meta http-equiv="X-UA-Compatible" content="IE=11" />  
        <meta http-equiv="X-UA-Compatible" content="IE=12" />
        <meta http-equiv="X-UA-Compatible" content="IE=13" />

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">       
    <link href="assets/css/Gallery.css" rel="stylesheet" type="text/css" />
    <!--<script src="js/lightbox-2.6.min.js"></script>-->
    <link rel="stylesheet" href="css/screen.css" media="screen" />
    <link rel="stylesheet" href="css/lightbox.css" media="screen" />

this is code behind of course page

protected void Page_Load(object sender, EventArgs e)
{
    Page.MetaDescription = "hi";
}
