title: Crashing when trying to see if my Cell is checked or unchecked
body: <p>My system clock is 9/16/2014 (Tuesday)</p>
  
  <p>But in code, I'm always jumping to Monday.</p>
  
  <pre><code>DayOfWeek dow = DateTime.Now.DayOfWeek;
  int columnNumber = 0;
  
  columnNumber = columnNumber + 0;
  
  foreach ( DataGridViewRow row in dataGridView1.Rows )
  {
    switch ( dow )
    {
    case DayOfWeek.Monday:
      columnNumber = 4;
      if (Int32.Parse(row.Cells[columnNumber].Value.ToString()) == 1)
      {
           row.Cells["activeTodayDataGridViewCheckBoxColumn"].Value = true;
      }
      break;
  </code></pre>
  
  <p>I have a <code>DataGridView</code></p>
  
  <ul>
  <li>Columns 0&mdash;3 are <code>Text</code></li>
  <li>Columns 4&mdash;9 are <code>DataGridViewCheckBoxColumn</code></li>
  </ul>
