title: TrackBar Control acting as a Range Selector with Multiple Thumbs
body: <p>I am after a control which works similarly to a TrackBar control but has three thumbs, one for selecting a value and two others for selecting the minimum and maximum values on the same control.</p>
  
  <p>I have searched Google for this and I have found a lot of people asking for the same thing (or similar range control) but I haven't found any resources showing how to do this or examples of code.</p>
  
  <p>Does anyone know if I can find a resource for this? If not.. How would I go about creating a control like this?</p>
  
  <p>Many thanks for any information or advice you can provide me with. </p>
