winForm下改变DataGridView的某行某列的值和控制列的位置

控制DataGrieView的某列的位置可以这样做：

this.dataGridView1.Columns["OperType"].DisplayIndex=5;

则OperType列的位置就是在第6列上。DisplayIndex的索引是从0开始的。

如果改变DataGridView的某行某列的值则可以这样做：

 

private void dgv_serverLRRecord_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
        {
　　　　　　　//以下两行分别是设置列标头居中和单元格内数据居中
            this.dgv_serverLRRecord.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;
            this.dgv_serverLRRecord.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;

            int _count = this.dgv_serverLRRecord.Rows.Count;
            //if (!this.dgv_serverLRRecord.Columns.Contains("LRType"))
            //{
            //    this.dgv_serverLRRecord.Columns.Add("LRType", "借还车类型");
            //    this.dgv_serverLRRecord.Columns["LRType"].Width = 150;
            //    this.dgv_serverLRRecord.Columns["LRType"].DisplayIndex = 5;//控件列的位置
            //    this.dgv_serverLRRecord.Columns["LRType"].Visible = false;
            //}
            for (int i = 0; i < _count; i++)
            {
                string _tempVal = string.Empty;
                if (this.dgv_serverLRRecord.Rows[i].Cells["OperType"].Value.ToString() == "1")
                {
                    _tempVal = "借车";
                }
                else if (this.dgv_serverLRRecord.Rows[i].Cells["OperType"].Value.ToString() == "2")
                {
                    _tempVal = "还车";
                }
                else
                {
                    _tempVal = "异常记录";
                }
                this.dgv_serverLRRecord.Rows[i].Cells["OperType"].Value = _tempVal;
                //this.dgv_serverLRRecord.Rows[i].Cells["LRType"].Value = _tempVal;
            }
            this.dgv_serverLRRecord.Columns["BikeSN"].HeaderText = "自行车编号";
            this.dgv_serverLRRecord.Columns["RentalName"].HeaderText = "租凭点名称";
            this.dgv_serverLRRecord.Columns["MachineSN"].HeaderText = "停车桩编号";
            this.dgv_serverLRRecord.Columns["RentalSN"].HeaderText = "租赁点编号";
            this.dgv_serverLRRecord.Columns["Premoney"].HeaderText = "交易前余额(元)";
            this.dgv_serverLRRecord.Columns["Premoney"].Width = 113;
            this.dgv_serverLRRecord.Columns["Money"].HeaderText = "交易金额(元)";
            this.dgv_serverLRRecord.Columns["Money"].Width = 110;
            this.dgv_serverLRRecord.Columns["OperType"].HeaderText = "借还车类型";
            this.dgv_serverLRRecord.Columns["OperDate"].HeaderText = "借还车时间";
            this.dgv_serverLRRecord.Columns["OperDate"].Width = 103;
            this.dgv_serverLRRecord.Columns["Address"].HeaderText = "租赁点地址";
            this.dgv_serverLRRecord.Columns["Address"].Width = 160;
            this.dgv_serverLRRecord.Columns["AllMoney"].Visible = false;
            this.dgv_serverLRRecord.Rows[0].Cells[0].Selected = false;
        }
