title: System.ArgumentException: DataGridViewComboBoxCell value is not valid
body: <pre><code>dataGridView.Rows.Add(
      metaData.Offset.ToString("X2"),
      metaData.Length,
      metaData.Format,        // This parameter goes to a ComboBox cell which throws an
      metaData.Description,   //     exception above                       
      null,
      null);
  </code></pre>
