      { 
       isset.Visible = notsesstion.Visible = false; 
       if (!String.IsNullOrEmpty(Session["name"] as String)) 
       {

      <!-- Brand and toggle get grouped for better mobile display --> 
      <div class="navbar-header"> 
       <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar"> 
        <span class="sr-only">Toggle navigation</span> 
        <span class="icon-bar"></span> 
        <span class="icon-bar"></span> 
        <span class="icon-bar"></span> 
       </button> 

       <a class="navbar-brand" href="HomePageClient.aspx"> 
        <img alt="Brand" src="images/logo2.png" height="50" /> 
       </a> 

      </div> 
      <div id="notsesstion" runat="server">

事情是這樣的：

<% if (!String.IsNullOrEmpty(Session["name"]){ %>    
    // html code here 
<% } %>
