title: C# TabControl Selected event seems to not work
body: <p>I am trying to access the event handler for selecting a tab, basically I have 3 tab pages inside of tabControl1. I want to be able to manipulate what is displaying in a listbox based on what tab is selected at the moment as a new tab is selected.
  This does not work, anytime a tab page is selected it fails to show the message box, (when that line is uncommented)</p>
  
  <pre><code>private void tabControl1_Selected(Object sender, EventArgs e)
  {
      //MessageBox.Show(tabControl1.SelectedIndex.ToString());3
  
      if (tabControl1.SelectedIndex == 0)
      {
          //do something
      }
  }
  </code></pre>
