c＃datagridview组合框列错误

Question

我收到此错误：“DataGridViewComboBoxCell值无效。” 这是我的代码

 DataGridViewComboBoxColumn dgvcombo = new DataGridViewComboBoxColumn();
                            dgvcombo.ValueType = typeof(decimal);
                            dgvcombo.Name = Name;
                            dgvcombo.DataPropertyName = colname;
                            dgvcombo.DataSource = dtsource;
                            dgvcombo.DisplayMember = DisplayMember;
                            dgvcombo.ValueMember = ValueMember;
                            dgvcombo.Visible = Visible;
                            dgvcombo.Width = width;
                            DataGridView.Columns.Add(dgvcombo);

每次为所有行生成Combobox列时，我都会收到此错误

你可以试试这个

DataGridViewComboBoxColumn dgvcombo =
            dataGridView1.Columns[0] as DataGridViewComboBoxColumn;
