title: label.visible = true not working
body: <p>The visible function doesnt work, but why? Is a true set in a callback not allowed?. When I set the visible to true on top of the page(<code>_Default : System.Web.UI.Page</code>)  it is working.</p>
  
  <pre><code>information_remedyID.Visible = true;
  information_remedyID.Text = inquiryId;
  </code></pre>
  
  <p>TOP Class:</p>
  
  <pre><code>public partial class _Default : System.Web.UI.Page
