title: Do function on only 1 Control of NumericUpDown
body: <p>I let a supertooltip (from DotNetBar) appear on every control of NumericUpDown. But I only need a supertooltip on the TextBox of NumericUpDown. Here is my current code:</p>
  
  <pre><code>foreach (Control c in NumericUpDown.Controls)
  {
      NumericUpDownToolTip.SetSuperTooltip(c, NumericUpDownSuperToolTip);
  }
  
  //Declarations:
  //NumericUpDownToolTip is a SuperToolTip from DotNetBar
  //NumericUpDownSuperToolTip is the configuration of the SuperToolTip (for example: the text of the tooltip)
  </code></pre>
  
  <p>So how do I set the tooltip only on the textbox?</p>
