title: How to add tooltip to user defined textbox on a winform
body: <p>I have a <code>uvSelfLoadingTextBox</code> with multiple instances on a form.
  I would like to load the tooltip with the <code>_value</code> property at run time.</p>
  
  <p>I've tried </p>
  
  <pre><code>public ucSelfLoadingTextBox()
  {
      Windows.Forms.ToolTip myToolTip;
      myToolTip.AutomaticDelay = 5000;
      myToolTip.AutoPopDelay = 50000;
      myToolTip.InitialDelay = 100;
      myToolTip.ReshowDelay = 500;
  
      myToolTip.SetToolTip(this, _value);
  </code></pre>
  
  <p>inside the control but that does not work.</p>
  
  <p>I have tried using the tooltip that is dragged onto the form</p>
  
  <pre><code>    ucSelfLoadingLogicTextBox uc = new ucSelfLoadingLogicTextBox();
      toolTipA.SetToolTip(uc,uc._value );
  </code></pre>
  
  <p>and that does not work.</p>
  
  <p>What is the correct way to do this?</p>
