title: Disable sorting when clicking DataGridView column header
body: <p>I have a <code>DataGridView</code> column header. When I click that header, the data is resorted according to the value.</p>
  
  <p>I don't want that.</p>
  
  <p><code>DataGrid</code> has an <code>AllowSort</code> property. DataGridView doesn't have that. Anything I can do?</p>
