LinkDataBase link=new LinkDataBase();
string tempsql=" select * from prodtable ";
DataTable mytable=new DataTable();
DataSet ds=new DataSet();
ds=link.SelectDataBase(tempsql,"prodtable");
this.dgview_prod.DataSource = ds.Tables[0];
this.dgview_prod.Columns[0].HeaderText = "货品编号";
this.dgview_prod.Columns[1].HeaderText = "物料编号";
this.dgview_prod.Columns[2].HeaderText = "物料名称";
this.dgview_prod.Columns[3].HeaderText = "数量";
this.dgview_prod.Columns[4].HeaderText = "单位";
this.dgview_prod.Columns[5].HeaderText = "单价";
this.dgview_prod.Columns[5].HeaderText = "小包装";
this.dgview_prod.Columns[5].HeaderText = "大包装";
this.dgview_prod.Columns[5].HeaderText = "备注";
this.dgview_prod.Columns[5].HeaderText = "开单日期";
this.dgview_prod.Columns[5].HeaderText = "开单";
DataGridViewComboBoxColumn dgview_prodtype=new DataGridViewComboBoxColumn();

我想将其类型设为DataGridViewComboBoxColumn

DataGridView?

dataGridView1.Columns[i].ValueType = System.Type.GetType("System.Int32");
