title: Making text box hidden in ASP.NET
body: <p>I am using ASP.NET 3.5 and C#.</p>
  
  <p>On my page I need to have a Text box that must not be visible to the user but it MUST be there when you look at the Page Source, reason being, another program called Eloqua will be looking at the page source and it must get the value of that text box.</p>
  
  <p>The value of that text box will be populated based on what the user selects.</p>
  
  <p>Thus, I cant set the text box property to Visible = False because then it will not be in the source HTML and I can't set the Enabled = False because I do not want the user to see the text box.</p>
  
  <p>Is there some property I can use to make this text box hidden to the user but still visible in the page source?</p>
  
  <p>My ASP.NET text box</p>
  
  <pre><code>&lt;asp:TextBox ID="txtTester" runat="server"&gt;&lt;/asp:TextBox&gt;
  </code></pre>
