title: ASP.NET content incode id
body: <p>I recently started using Masterpages, the thing is I would like to add text in code to an asp:Content tag.</p>
  
  <p>So my content page markup code is:</p>
  
  <pre><code>&lt;%@ Page Language="C#" MasterPageFile="~/Template.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ASP_Test_WebApp.Default" %&gt;
  &lt;asp:Content id="TEST" ContentPlaceHolderID="Main" Runat="Server" /&gt;
  </code></pre>
  
  <p>So now I would like to add Contents to the "TEST" id incode.</p>
  
  <p>But my in code doesn't recognize TEST. If I don't use a masterpage and I give an id to a tag my in code reconigzes it, but now that I started using masterpages it doesn't.</p>
  
  <p>What am I doing wrong?</p>
