title: Setting DataGridView Column type to drop down at run time (C#.net)
body: <p>I have a datagridview its datasource is set to a data view -> data table and rows &amp; columns are auto generated at run time.</p>
  
  <pre><code>    dtable.Columns.Add("1", typeof(int));
      dtable.Columns.Add("2", typeof(string));
      dtable.Columns.Add("3", typeof(string));
      datagridview1.DataSource = dtable;
  </code></pre>
  
  <p>I want column 3 to be a drop down type and have 3 options in it. How do I do that at run time as I only populate the grid at run time.</p>
