DataGridViewComboBoxCell用法问题

请问我使用   DataGridViewComboBoxCell时，在指定单元格中显示下拉框，这样写问什么不行，谢谢各位啦

                      DataGridViewComboBoxCell dgvc1 = new DataGridViewComboBoxCell();
                      dgvc1.Items.AddRange(new object[] { "ID", "X", "Y", "Z", "Ca", "Mg", "Na","K","NaK","HCO3","CO3","Cl","SO4" });
                      DataGridView1.Rows[0].Cells[1] = dgvc1;
显示结果，下拉框点击没有变化
