datagridview下拉框

下面介绍Winform中DataGridView的DataGridViewComboBoxColumn的使用方法：

//首先获取数据源

//自己建立的静态数据源，你也可以从数据库读取

  DataTable dtb = new DataTable();
                 dtb.Columns.Add("目标", typeof(string));
                 DataRow drow = dtb.NewRow();
                 drow["目标"] = "型号";
                 dtb.Rows.Add(drow);
                 drow = dtb.NewRow();
                 drow["目标"] = "厂牌";
                 dtb.Rows.Add(drow);
                 drow = dtb.NewRow();
                 drow["目标"] = "批号";
                 dtb.Rows.Add(drow);
                 drow = dtb.NewRow();
                 drow["目标"] = "货期";
                 dtb.Rows.Add(drow);
                 drow = dtb.NewRow();
                 drow["目标"] = "库存量";
                 dtb.Rows.Add(drow);
                 drow = dtb.NewRow();
                 drow["目标"] = "起订量";
                 dtb.Rows.Add(drow);
                 drow = dtb.NewRow();
                 drow["目标"] = "基础价格";
                 dtb.Rows.Add(drow);
                 drow = dtb.NewRow();
                 drow["目标"] = "库存地点";
                 dtb.Rows.Add(drow);
                 drow = dtb.NewRow();
                 drow["目标"] = "封装方式";
                 dtb.Rows.Add(drow);
                 drow = dtb.NewRow();
                 drow["目标"] = "包装方式";
                 dtb.Rows.Add(drow);
                 drow = dtb.NewRow();
                 drow["目标"] = "图片地址";
                 dtb.Rows.Add(drow);
                 drow = dtb.NewRow();
                 drow["目标"] = "产品描述";
                 dtb.Rows.Add(drow);
                 drow = dtb.NewRow();
                 drow["目标"] = "pdf索引地址";
                 dtb.Rows.Add(drow);
                 this.DGV_ExcelToDgv.DataSource = dtb;

//接下来就是把数据源绑定到DataGridViewComboBoxColumn

DataGridViewComboBoxColumn comUserName = new DataGridViewComboBoxColumn();
comUserName.HeaderText = "目标";//列头显示的汉字
comUserName.DisplayStyle = DataGridViewComboBoxDisplayStyle.ComboBox;
comUserName.DataSource = dtb;//下拉框绑定的数据源
comUserName.ValueMember = "目标";//要和上面**处的一样
DGV_ExcelToDgv.Columns.Add(comUserName);
