title: Changing text of a combobox in a different tab
body: <p>I have a combo box which I need to mirror in another tab page in a C# winforms based application.</p>
  
  <p>I have perfectly working code for when you select a different item from the drop down list.  Unfortunately, however, when I change the <code>Text</code> of a tab that has not been clicked on yet nothing actually happens.</p>
  
  <p>If I first click each tab then everything works as expected.</p>
  
  <p>Now I'm putting this down to some form of lack of initialisation happening first.  So I've tried to select each tab in my constructor.</p>
  
  <pre><code>tabControlDataSource.SelectedIndex = 0;
  tabControlDataSource.SelectedIndex = 1;
  // etc
  </code></pre>
  
  <p>But this doesn't work.</p>
  
  <p>I've also tried calling <code>tabControlDataSource.SelectTab( 1 )</code> and still it doesn't work.</p>
  
  <p>Does anyone know how I can force the tab to "initialise"?</p>
