for (int i = 0; i < 5; i++)//添加5行，第一列是下拉框 { dataGridView1.Rows.Add(new object[2] { "", "测试文本列"+i }); DataGridViewComboBoxCell cell = dataGridView1.Rows[i].Cells[0] as DataGridViewComboBoxCell; cell.Items.Add("选项"+(i+1)); cell.Items.Add("选项" + ( i + 2)); cell.Items.Add("选项" + ( i + 3)); } dataGridView1.Refresh(); //获取指定行的cell单元格下拉框里的所有数据 foreach (object obj in cell.Items) { string str = obj.ToString(); }
