dataGridView 设置

            //窗体加载事件
            //内容居中
            dataGridView1.RowsDefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;
            //列名居中
            dataGridView1.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;
            //第一列禁止修改
            dataGridView1.Columns[0].ReadOnly = true;
            //单元格第一列第一行 背景色
            dataGridView1.Rows[0].Cells[0].Style.BackColor = Color.FromArgb(((int)(((byte)(255)))), ((int)(((byte)(192)))), ((int)(((byte)(128)))));
去掉最左侧
RowHeadVisible属性设置为false

 
            //添加行
            for (int i=1;i<=6;i++)
            {
                int index = this.dataGridView1.Rows.Add();
                this.dataGridView1.Rows[index].Cells[0].Value = i;

            }


////第一行第一列 添加数据
            //dataGridView1.Rows[0].Cells[0].Value = "1";
            //dataGridView1.Rows[1].Cells[0].Value = "2";
            //dataGridView1.Rows[2].Cells[0].Value = "3";
            //dataGridView1.Rows[3].Cells[0].Value = "4";
            //dataGridView1.Rows[4].Cells[0].Value = "5";
 //循环读取DataGridView
            foreach (DataGridViewRow row in this.dataGridView1.Rows)
            {
                object cell0 = row.Cells[0].Value; //1
                object cell1 = row.Cells[1].Value;  // 2
                object cell2 = row.Cells[2].Value;  //3
                object cell3 = row.Cells[3].Value;  //4
                object cell4 = row.Cells[4].Value;  //5
                object cell5 = row.Cells[5].Value;  // 6
                object cell6 = row.Cells[6].Value;  // 7
            }

 原来在dataGridView的编辑列中有个属性DataPropertyName,在这里设置字段名称即可显示,查询结果的字段,全部添加上列后,就不会自动产生列了 //【没有测试】

 在编辑列中, HeaderText 姓名 是显示的字段

Data     DataPropertyName  姓名  -- 这是对应的数据库查询出数据的列

Design  (Name)  dgv姓名  - -这是 获取编辑框的内容

           //隐藏某列
            dgv.Columns["产品ID"].Visible = false;
            dgv.Columns["别名"].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;//设置某列  自动列宽

            dgv.Columns["别名"].SortMode = DataGridViewColumnSortMode.Programmatic; //自定义排序

   dgv.Sort(dgv.Columns[nColumnIndex], System.ComponentModel.ListSortDirection.Descending); //设置某列排序

设置显示格式 百分比显示

//dgv.Columns["A"].DefaultCellStyle.Format = "P"; //以百分号显示 "0\%";

dgv.Columns["A"].DefaultCellStyle.Format = "0.00\%"; //以百分号显示 "0\%";
