title: How to display DataGridViewCell tooltip with title in c++/cli
body: <p>I'm using C++/CLI with .net 4.5. I try to display tool tips on <code>DataGridViewCell</code> but with <strong>title</strong>. I can easily set the text (property <code>ToolTipText</code>) but I found no way to add a title. In class <code>ToolTip</code> there is a property <code>ToolTipTitle</code> but it is neither accessible from the <code>DataGridViewCell</code> object, nor usable via the underlying <code>ToolTip</code> used by the <code>DataGridView</code>. I tried either to set it in the <code>CellValueNeeded</code> and in the <code>CellToolTipTextNeeded</code> events but nothing...</p>
  
  <p>My next try was to directly set the <code>ToolTip</code> to the <code>DataGridViewCell</code> but I rapidly discovered that such a cell was not inherited from <code>Control</code>... :-(</p>
  
  <p>I succeeded to display a titled tool tip by calling <code>ToolTip::Show()</code> but I "was told" that we should never call <code>ToolTip::Show()</code> and let the framework do the job.</p>
  
  <p>Is there something I missed or fully handling the tool tip by hand is my only solution?</p>
  
  <p>Thanks in advance for your help! </p>
