title: Win Forms DataGridView - showing hierarchical parent/child rows
body: <p>I am trying to construct a datagridview that will show a number of rows with a particular set of fields, but also allow me to show some 'subrows' ie rows that can be expanded below the parent row in question (if that parent row has these children - part of the datasoruce) the only real problem is that the expanded rows will have completely different fields(columns)</p>
  
  <p>is this possible with a standard datagridview in a windows form?
  I am presuming somehow I would have to shoehorn in a new datagridview in a row of the parent grid.</p>
  
  <p>We do have the Syncfusion suite which includes the gridgroupingcontrol. but after much hair pulling and other pains. I have given up on that completely.</p>
