title: How to show Enum type members in a DataGridViewComboBox?
body: <p>What else I have to do in order to show <code>ReadAccess</code> enum members in this DatagridViewComboBox?  </p>
  
  <pre><code>ReadDataGridViewComboBoxColumn.Items.Clear();
  ReadDataGridViewComboBoxColumn.Items.AddRange(ReadAccess.None, ReadAccess.Allowed);
  ReadDataGridViewComboBoxColumn.ValueType = typeof(ReadAccess);
  </code></pre>
  
  <p>here is designer-generated codes about DataGridView:</p>
  
  <pre><code>this.rolesDataGridView.AutoGenerateColumns = false;
  this.rolesDataGridView.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] {
  this.TableNameDataGridViewTextBoxColumn,
  this.ReadDataGridViewComboBoxColumn,
  this.WriteDataGridViewComboBoxColumn,
  this.ReadCodeDataGridViewComboBoxColumn,
  this.ProcessDataGridViewCheckBoxColumn,
  this.AdministrateDataGridViewCheckBoxColumn});
  this.rolesDataGridView.DataSource = this.bsTablePermissions;</code></pre>
  
  <p>and finally, in after <code>InitializeComponent();</code>, i'm setting DataGridView's DataSource:</p>
  
  <pre><code>this.rolesDataGridView.DataSource = this.RoleTablePermissions;  // a bindingsource list</code></pre>
