title: TabControl with the same controls on each tab
body: <p>I'd like have the same controls on all pages of <code>TabControl</code>.</p>
  
  <p>I have <code>tabControl</code> without any <code>tabPages</code> in my form. And in the same form I have some controls that I want automatically add to each <code>tabPage</code>. And work with them. How can I do that?</p>
  
  <p>I'd like something like this:</p>
  
  <pre><code>    public chatForm(string chatID, object conversation)
      {
          InitializeComponent();
  
          createNewTab(chatID, conversation);
      }
  
      internal void createNewTab(string chatID, object conversation)
      {
          ISIMtabPage newTab = new ISIMtabPage();
          newTab.Text = Converter.getContactName(conversation);
          newTab.Name = chatID;
  
          newTab.conversation = conversation;
  
          newTab.avatarBox.Image = new Bitmap("graphics\\anonymousAvatar.png");// how can I work with this control in the selected tab?
  </code></pre>
  
  <p>How can I do that all controls will be automatically in each <code>tabPage</code> and how can I work with them?</p>
