    text
    copied!<p>I have a simple ASP.NET application which has one master page called MasterPage.master. In MasterPage.master I have a Label called <code>lblStatus</code>. I want to update the text of this label when certain events happen in the website and always display the latest status no matter which web page I am on in the site.</p> <p>This is what I'm thinking of doing, but I'm unsure if this is the most elegant:</p> <ol> <li>Create a new class file with the code to update session state <code>Session["status"]</code></li> <li>Call a method in this new class file to update Session state whenever something happens</li> <li>In the PageLoad event of the MasterPage.master page, update the <code>lblStatus.Text</code> with <code>Session["status"]</code></li> </ol> <p>Questions</p> <ol> <li>Should I use a <code>Literal</code> instead of a <code>Label</code>? </li> <li>Would it be better to do it another way?</li> </ol> <p>Thanks, here's my code so far in MasterPage.master:</p> <pre><code>&lt;%@ Master Language="C#" %&gt; &lt;script runat="server"&gt; public string StatusText { get { return ltlStatus.Text; } set { ltlStatus.Text = value; } } &lt;/script&gt; &lt;html&gt; &lt;head runat="server" id="Header"&gt; &lt;asp:contentplaceholder id="ContentPlaceHolderScript" runat="server" /&gt; &lt;title&gt;MooDB - &lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;form id="frmMaster" runat="server"&gt; &lt;div&gt; &lt;asp:Menu ID="mnuNav" Orientation="Horizontal" runat="server"&gt; &lt;.. removed for brevity ..&gt; &lt;/asp:Menu&gt; &lt;/div&gt; &lt;div&gt; &lt;asp:Literal ID="ltlStatus" runat="server" /&gt; &lt;/div&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>I'm unsure of the next bit. Do I need to copy this code onto every page in my site:? </p> <pre><code>&lt;%@ Page Language="C#" %&gt; &lt;script runat="server"&gt; private void ChangeStatus(string newStatus) { ((SiteMaster)this.Master).StatusText = newStatus; } &lt;/script&gt; &lt;asp:Content ContentPlaceHolderID="contentMain" runat="server" ID="Main" &gt; &lt;... my page content ...&gt; &lt;/asp:Content&gt; </code></pre> <p>Sorry I'm new to ASP.NET and I'm not sure what to do. What is SiteMaster?</p>
