title: DataGridView's Column name not found
body: <p>Why do I get the exception that Column Name is not found for MyEntity as well as FullName Columns?  Although I see the column names being displayed in UI.</p>
  
  <pre><code>InitializeComponent();
  
  dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
  
  foreach (DataGridViewRow row in dataGridView1.SelectedRows)
  {
      int rowIndex = dataGridView1.Rows.IndexOf(row);
      myObject = dataGridView1.Rows[rowIndex].Cells["MyEntity"].Value as IEntityObject;
      fileName = dataGridView1.Rows[rowIndex].Cells["FullName"].Value.ToString();       
  }
  </code></pre>
