c# - 如何填充 DataGridViewComboBoxColumn

Question

我有DataGridViewComboBoxColumn我的datagridview，我想linq在运行时填充使用：

我试试这个

var line = from li in dbdata.Production_lines select li;
grdEmp.Rows.Add();

(grdEmp.Rows[count].Cells["Line"] as DataGridViewComboBoxCell).DataSource = line;
(grdEmp.Rows[count].Cells["Line"] as DataGridViewComboBoxCell).ValueMember = "L_id";
(grdEmp.Rows[count].Cells["Line"] as DataGridViewComboBoxCell).DisplayMember = "L_id";

但这没有用。那么如何将数据绑定到ComboBox我的DataGridView

Answer 1

尝试这个 ：

DataGridViewComboBoxColumn combo = (DataGridViewComboBoxColumn)grdEmp.Columns["Line"];

combo.DataSource = line;
combo.ValueMember = "L_id";
combo.DisplayMember = "L_id"; // I also suspect this should be a text column
