title: Make cells visible DataGridView WinForms C#
body: <p>Is there any way to make some cells invisible in a <code>DataGridView</code> ?</p>
  
  <p>Basically I am making an invoice application in which certain cells have no meaning when a particular setting is used.
  I have currently made those cells ReadOnly with no value but it will be cool if they could become invisible/transparent.</p>
  
  <p>Any free 3rd party Control will also do !</p>
