How to give session in menuitem

Hi Jasna,
I am not getting Exactly what u want, hope this may help u..
session used in masterPage. Hope u may get some idea..

Note the @ Master instead of the usual @ Page declaration.
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="Master1.master.cs" Inherits="Master2"%>

To change the Master Page dynamically..
Create a new Master Page different from the first. Then add buttons to change between the Master Pages.

void LinkButton1_Click(Object sender, EventArgs e)
{
Session["masterpage"] = "Master1.master";
Response.Redirect(Request.Url.ToString());
}

Now to dynamically load the Master Page:

public partial class About : System.Web.UI.Page {
void Page_PreInit(Object sender, EventArgs e)
{
if(Session["masterpage"] != null)
{
this.MasterPageFile = (String) Session["masterpage"];
}
}
}

The front end pages should look something like this:
Home.aspx
<%@ Page Language="C#" MasterPageFile="~/Master1.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Home" Title="The Home Page" %>
<%@ MasterType virtualpath="~/Master1.master" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<span style="color: #ffffff"></span>
<span style="color: #ffffff"></span><span style="color: #ffffff">Welcome to the website</span>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder2" Runat="Server">
<h1>
give Comment if it helps you.</h1>
</asp:Content>

Default.aspx
<%@ Page Language="C#" MasterPageFile="~/Master1.master" AutoEventWireup="true" CodeFile="About.aspx.cs" Inherits="About" Title="About Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<h1>
<span style="color: #ffffff">About the site</span></h1>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder2" Runat="Server">
<h1>This is the about page</h1>
</asp:Content>

The Master Pages should look something like this:
<form id="form1" runat="server">
<div>
<asp:contentplaceholder id="ContentPlaceHolder1" runat="server"></asp:contentplaceholder>
<table border="0" cellpadding="0" cellspacing="0" style="width: 100%; height: 100%">
<tr>
<td colspan="2" bgcolor="#ccffcc" height="48" valign="top">
<asp:Menu ID="Menu1" runat="server" Orientation="Horizontal">
<Items>
<asp:MenuItem NavigateUrl="Default.aspx" Text="Home" Value="Home"></asp:MenuItem>
<asp:MenuItem NavigateUrl="About.aspx" Text="About" Value="About"></asp:MenuItem>
</Items>
</asp:Menu>
<asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click">Plain</asp:LinkButton>
</td>
</tr>
<tr>
<td bgcolor="#ccffcc" valign="top" width="48">
<asp:Image ID="Image1" runat="server" ImageUrl="images.jpg" Width="48px" />
</td>
<td bgcolor="#ccffcc" valign="top">
<asp:ContentPlaceHolder ID="ContentPlaceHolder2" runat="server">
</asp:ContentPlaceHolder>
</td>
</tr>
<tr>
<td colspan="2" bgcolor="#ccffcc" height="48" valign="top">Copyright..</td>
</tr>
</table>
</div>
</form>
