title: How can I display a tooltip showing the value of a trackbar in WinForms
body: <p>I'm new to C# and WinForms so please excuse me is this is a bit of a newbie question.</p>
  
  <p>I'm trying to add a tooltip to my TrackBar control which shows the current value of the bar as you drag it. I've instantiated a ToolTip object and tried the following handler code but it doesn't show any tooltip:</p>
  
  <pre><code>private void trackBar1_Scroll(object sender, EventArgs e)
  {
     toolTip1.SetToolTip(trackBar1, trackBar1.Value.ToString());
  }
  </code></pre>
