Updating the master page when the control is within an update panel on the content page
I have an application which has a control within a update panel but needs to update a part of the master page aswel - i m not sure if this can be done?

The 

     <asp:ScriptManager ID="ScriptManager" runat="server" />

is within the master page
and the part of the master page i want to update is the following:

    <div id="divPanelMyCover" class="divPanelMyCover" runat="server">
                                    <div class="sectionYourProtection">
                                        <div class="sectionPadding">
						                    <h4>Title</h4>
						                </div>
                                        <div class="innerPanelMyCover">
                                            <br/>
                                            <ul class="bulletList" type="square">
                                                <li><span class="spBold">Monthly Payment: </span><asp:Label ID="lblMonthlyPayment" runat="server" Text=""></asp:Label                                                                                        </div>
       </div>
     </div>	

code behind:

     lblMonthlyPayment.Text = Convert.ToString(application.Premium);


The lblMonthlyPayment needs to change depending on what the user selects on a content page but as the control is within an update panel it is not working.

Content page:

     <asp:UpdatePanel ID="upUpSell" runat="server">
                 <ContentTemplate>  
    <div id ="divSlider" runat="server" visible="false">
                            <br />
                            <h3>If you want, you can change the amount ... </h3>
                                                        <hr />
                            <div class="sliderContainer"> 
                               <telerik:RadSlider id ="rdSlider" AutoPostBack="true" runat="server" Orientation="Horizontal" Width="450"
                                            Height="70" MinimumValue="0" MaximumValue="50" LargeChange="10" TrackPosition="BottomRight"
                                            ItemType="Tick" IsSelectionRangeEnabled="false" SelectionStart="10" SelectionEnd="30" Skin="Default" DragText="Select Premium" >
                                 
                                </telerik:RadSlider>
                            </div>
                            <asp:Label ID="lblValue" runat="server" Text="" Visible="false"></asp:Label>
                        </div>                   


c#

    protected void Page_Load(object sender, EventArgs e)
        {
            //if (!Page.IsPostBack)
                        
             //Pre-populate the screen with data from ApplicationBO
            ApplicationBO application = (ApplicationBO)Session["Application"];

            if (!Page.IsPostBack)
            {
                if (Session["Application"] == null)
                    application = new ApplicationBO();
                else
                    application = (ApplicationBO)Session["Application"];
                lblclientName.Text = application.FirstName;
                rdSlider.Value = Convert.ToDecimal(application.Premium);
                lblMonthlyPayment.Text = Convert.ToString(application.Premium);
            }
            
            divSlider.Visible = true;
                      
            string upsellValue = Convert.ToString(application.Premium);

            if (divSlider.Visible == true)
            {
                upsellValue = Convert.ToString(rdSlider.Value);

                // Save the current page information
                application.Premium = Convert.ToDecimal(upsellValue);

            }
