dz论坛如何做网站地图/在线建站网页制作网站建设平台

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;
 }
