title: DataGridView column bound to a read-only field must have ReadOnly set to True
body: <p>I know there must be a simple solution to this question, but I seem to be missing the answer.
  I have a Visual Studio 2008 Winforms application where I created a datagridview to display data to users. In the datagridview I allow the users to edit information. One of the cells is set to read only and the users want to be able to edit this information now. When I go into the datagridview designer to set the cell to Readonly = False the change does not get saved. Does not matter what I do the change WILL not get saved. I am now looking into changing this at run time using the code below:</p>
  
  <p>When I use that code I get the error mentioned in the title. It seems to me that I am stuck now... I can't change the cell to readonly = false using the Visual Studio designer. I can't set the cell to readonly = false at runtime.</p>
  
  <p>Question: What am I doing wrong? Is there something else I can do? This is quite a sizable application for multiple users and this is a request made by most of the users.</p>
  
  <p>Any help would be appreciated.</p>
