title: DataGridViewCheckBoxCell is not getting checked
body: <p>DataGridViewCheckBoxCell is not getting checked.  I have inserted the first column like this  </p>
  
  <pre><code>DataGridView1.Columns.Insert(0, new DataGridViewCheckBoxColumn { Name = "Print" });
  </code></pre>
  
  <p>This is not working  </p>
  
  <pre><code>DataGridView1.Rows[0].Cells[0].Value = true;
  </code></pre>
  
  <p>Neither this is working   </p>
  
  <pre><code>DataGridView1.Rows[0].Cells[0].Value = cell.TrueValue;
  </code></pre>
  
  <p>What could be the reason it is not getting checked?</p>
