         }

         //得到GridControl单元格的值： string d =gridView1.GetRowCellDisplayText(i,col); i代表行号，col代表标题

     }

 }

代码设定我需要的gridcontrol格式

效果如下：

c# 数据表DataTable给devexpress的gridControl提供数据源

https://jingyan.baidu.com/article/25648fc1d46dfb9191fd00c0.htmlc# 数据表DataTable给devexpress的gridControl提供数据源

c# 数据表DataTable给devexpress的gridControl提供数据源

             //绑定DataTable

             gridControl1.DataSource = dt;

             gridView1.OptionsCustomization.AllowColumnMoving = false;//如何让各列头禁止移动

             gridView1.OptionsCustomization.AllowFilter = false;//不允许过滤

             gridView1.OptionsCustomization.AllowSort = false;//不允许排序

             gridView1.OptionsCustomization.AllowGroup = false;//不允许分组

             gridView1.OptionsView.ShowGroupPanel = false;//不显示组面板

             gridView1.OptionsSelection.MultiSelect = true;//可以多选

gridcontrol-gridview各种设置

添加行号：

c# 数据表DataTable给devexpress的gridControl提供数据源

参考：http://www.cnblogs.com/liulunet/archive/2011/08/08/2131227.html

取第三行第三列单元格的值:
gridView2.GetDataRow(2)[2]
         private void gridView1_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)

         {

             if (e.Info.IsRowIndicator && e.RowHandle >= )

             {

                 e.Info.DisplayText = (e.RowHandle + ).ToString();

             }

         }

gridcontrol-GridView显示行号

4．得到GridControl的列数
        int a =gridView1.Columns.Count；
5．得到GridControl的行数
int b =gridView1.RowCount；
6．得到GridControl的列标题的值
         DevExpress.XtraGrid.Columns.GridColumn col = gridView1.Columns[0];第一个列表题
7.得到GridControl单元格的值：
string d =gridView1.GetRowCellDisplayText(i,col); i代表行号，col代表标题
  		string e =gridView1.GetFocusedRowCellValue("字段名");

添加引用

using System.Data;

创建表

//创建一个空表

DataTable dt = new DataTable();

//创建一个名为"Table_New"的空表

DataTable dt = new DataTable("Table_New");

创建列

c# 数据表DataTable给devexpress的gridControl提供数据源
//1.创建空列

DataColumn dc = new DataColumn();

dt.Columns.Add(dc);

//2.创建带列名和类型名的列(两种方式任选其一)

dt.Columns.Add("column0", System.Type.GetType("System.String"));

dt.Columns.Add("column0", typeof(String));

//3.通过列架构添加列

DataColumn dc = new DataColumn("column1",System.Type.GetType("System.DateTime"));

DataColumn dc = new DataColumn("column1", typeof(DateTime));

dt.Columns.Add(dc);
c# 数据表DataTable给devexpress的gridControl提供数据源

创建行

c# 数据表DataTable给devexpress的gridControl提供数据源
//1.创建空行

DataRow dr = dt.NewRow();

dt.Rows.Add(dr);

//2.创建空行

dt.Rows.Add();

//3.通过行框架创建并赋值

dt.Rows.Add("张三",DateTime.Now);//Add里面参数的数据顺序要和dt中的列的顺序对应 
//4.通过复制dt2表的某一行来创建
dt.Rows.Add(dt2.Rows[i].ItemArray);
c# 数据表DataTable给devexpress的gridControl提供数据源

赋值和取值

c# 数据表DataTable给devexpress的gridControl提供数据源
//新建行的赋值

DataRow dr = dt.NewRow();

dr[0] = "张三";//通过索引赋值

dr["column1"] = DateTime.Now; //通过名称赋值

//对表已有行进行赋值

dt.Rows[0][0] = "张三"; //通过索引赋值

dt.Rows[0]["column1"] = DateTime.Now;//通过名称赋值

//取值

string name=dt.Rows[0][0].ToString();

string time=dt.Rows[0]["column1"].ToString();
