it should still fix some issue What I would do for the particular case is:
i. Define the body as a server side control
code :
<body runat="server" id="masterpageBody">
<% MasterPageFile="..." %>

This might help you Yes.
You want to create a strongly-type master page and you can then access it's properties from your content page during Page_Load or wherever else.

may help you . I am talking specific to the URL you gave in your question: If you investigate the code, the basket part in the HTML part is :
code :
<div id="divBasketHeaderContent">
        <span id="ctl00_DesktopSideColumn_Basket_lblTxt">Your order</span>
function updateBasket(n, t, i) {
    document.getElementById("ctl00_DesktopSideColumn_Basket_modalProductId").value = n;
    var r = n + "#" + t + "#" + i + "#";
    __doPostBack("ctl00_DesktopSideColumn_Basket_UpdatePanel1", r)

Hope this helps I have prepared you complete solution to show you how you can do this.
First sample master. Take notice I have added ScriptManager to page and target label is inside content template:
code :
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site1.master.cs" Inherits="WebTester.Site1" %>
<!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 runat="server">
    <form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
                <asp:Label ID="SensorTemperatureLabel" runat="server" Text="TEMP"></asp:Label>
        <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
<%@ Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebTester.WebForm1" %>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Test" />
protected void Button1_Click(object sender, EventArgs e)
    Site1 site = this.Master as Site1;
    if (site != null)
        Label SensorTemperatureLabel = site.FindControl("SensorTemperatureLabel") as Label;
        SensorTemperatureLabel.Text = DateTime.Now.ToString();

Change label in masterpage in just one content page

I hope this helps . I think I get the gist of what you're asking:
Firstly, I would strongly type the master page, in your content page just below the @Page directive, by using the @MasterType directive:
code :
<%@ MasterType TypeName="*fully qualified type of your master page*" %>
public string MyText
  set { this.ViewState["TheText"]; }
this.Master.MyText = "Whatever you want to say!";
protected void Page_Load(object sender, EventArgs e)
  this.myControl.Text = Convert.ToString(this.ViewState["TheText"]);

this one helps. If your control "tbToolbar" is inside ContentPlaceHolder then you have to first find the ContentPlaceHolder by id and then you have to find your control from that ContentPlaceHolder. Take a look at below link:
