将组合框列添加到 winforms 中的数据表

Question

问题如何将 comboBoxcolumn 添加到 dataTable 而不仅仅是网格？我尝试将 "Connector Name" 列设置为 comboboxcolumn ，但显然我没有做对。

我有什么（片段）：

  if (_DtMain.Columns.Count == 0)
            {

                var cols = new List<DataColumn>();
                cols.Add(new DataColumn("PocketName", typeof(string)));
                cols.Add(new DataColumn("KeyIndex", typeof(string)));
                cols.Add(new DataColumn("SortOrder", typeof(int)));
                cols.Add(new DataColumn("ConnectorName", typeof(DataGridViewComboBoxColumn )));
                _DtMain.Columns.AddRange(cols.ToArray());
                dataGridView1.DataSource = _DtMain.DefaultView;

            }

这是我的新解决方案：

    if (_DtMain.Columns.Count == 0)
    {
        var colPN = new DataGridViewTextBoxColumn();
        var colCN = new DataGridViewComboBoxColumn();
        var colKI = new DataGridViewTextBoxColumn();
        var colSO = new DataGridViewTextBoxColumn();

        dgvHeaderEdit.Columns.Add(colPN);
        dgvHeaderEdit.Columns.Add(colCN);
        dgvHeaderEdit.Columns.Add(colKI);
        dgvHeaderEdit.Columns.Add(colSO);

        colPN.HeaderText = "Pocket Name";
        colPN.DataPropertyName = "Pocket Name";

        colCN.HeaderText = "Connector Name";
        colCN.DataPropertyName = "Connector Name";

        colKI.HeaderText = "Key Index";
        colKI.DataPropertyName = "Key Index";

        colSO.HeaderText = "Sort Order";
        colSO.DataPropertyName = "Sort Order";

        _DtMain.Columns.Add(new DataColumn("Pocket Name", typeof(string)));
        _DtMain.Columns.Add(new DataColumn("Connector Name", typeof(string)));
        _DtMain.Columns.Add(new DataColumn("Key Index", typeof(string)));
        _DtMain.Columns.Add(new DataColumn("Sort Order", typeof(int)));


 dgvHeaderEdit.AutoGenerateColumns = false;
                dgvHeaderEdit.DataSource = _DtMain.DefaultView;

这样使用：为 Grid 的数据源构建数据表时：

 DataTable dt = new DataTable();
            dt.Columns.Add("PocketName", typeof(string));
            dt.Columns.Add("KeyIndex", typeof(string));
            dt.Columns.Add("SortOrder", typeof(int));
            dt.Columns.Add("ConnectorName", typeof(int));

            dgv.DataSource = dt;

现在为 GridView 创建一个组合框列并为此组合框创建一个数据源。添加所有值以显示在 dtConnectorSource 的 ComboBox 中在 ComboBox 中用您需要的值填充 dtConnectorSource。

DataTable dtConnectorSource = new DataTable();

dtConnectorSource.Columns.Add("ConnectorName", typeof(int));
dtConnectorSource.Columns.Add("ConnectorNameDisplay", typeof(String));

    DataGridViewComboBoxColumn cmb = new DataGridViewComboBoxColumn ();
    cmb.DataSource = dtConnectorSource;
    cmb.DisplayMember = "ConnectorNameDisplay";
    cmb.ValueMember = "ConnectorName";

    cmb.DataPropertyName = "ConnectorName";

    dgv.Columns.Add(cmb);
