DevExpress.XtraGrid在winform里使用还挺麻烦，为了减少重复代码和代码复用，本人针对DevExpress.XtraGrid封装了一个Form的基类，其中涵盖了DevExpress.XtraGrid的基本用法，本文没有多少营养大家慎重观评啊，否则浪费您看岛国爱情动作片的宝贵时间本博概不负责！哈哈。

关注点： WinForm项目使用封装、继承；DevExpress.XtraGrid在WinForm的基本运用。

前戏：

本人已经逃离上海，回老家上成都发展了（继续做开发，到传统软件公司做安卓和.net c/s方向的开发）。求关照，求介绍私活(速度赚钱还房贷啊！！！回成都收入减少那是刚刚嘀)。认识多年的朋友邀请我作为的战略合作伙伴加入他成都的公司，本作离老家（重庆）近可经常回去和妻儿呆在一起，且收入下降的比例还可以接受，遂接受邀请，心不甘情不愿的回来了。去上海十一年，好像没什么收获啊，临走前想找个15k的工作说服自己留下来，天可怜见，不能如愿啊。

正文：

1)DevExpress.XtraGrid基本技巧

1.DevExpress控件组中的GridControl控件不能使横向滚动条有效。现象：控件中的好多列都挤在一起，列宽都变的很小，根本无法正常浏览控件单元格中的内容。

解决：

gridView1.OptionsView.ColumnAutoWidth属性是true，即各列的宽度自动调整，你把它设成false，就会出现了。

2.使单元格不可编辑。

gridcontrol -->gridview -->OptionsBehavior -->Editable=false

3.去除"Drag a Column Header Here To Group by that Column"或者改为中文

属性Gridview->Option View->Show Group Panel=false,就好了，“gridView.GroupPanelText”是设置改默认文字的属性。

4.数据绑定

（1）在GridControl控件面板中点击

（2）在出现的窗体中，点击左边的进行列名的编辑。点击上方的可添加一列，插入一列，移除一列。点击后在右边的属性面板中找到Caption设置显示的列标题和FieldName设置该列绑定数据的字段名，Visible设置列是否隐藏。

绑定代码：

gridControl2.DataSource = od.data_select("select * from tablename").Tables[0];//od是数据库操作类，data_select返回DataSet类型，绑定DataTable类型

5.选择某行数据触发时间

gridView2.RowClick += new DevExpress.XtraGrid.Views.Grid.RowClickEventHandler(gridView2_RowClick);

这样设置以后必须点击最左边的行编号才可以触发事件，需要设置gridcontrol -->gridview -->OptionsBehavior -->Editable=false即可点击任意单元格触发事件。

6.选择某行后获取当前表格数据

this.textBox1.Text = gridView2.GetDataRow(e.RowHandle)["列名"].ToString();

7.设置奇、偶行交替颜色

（1） OptionsView.EnableAppearanceEvenRow = true；OptionsView.EnableAppearanceOddRow = true;

（2）设置Appearance.EvenRow.BackColor和Appearance.OddRow.BackColor

8.在每行第一列显示行号

（1） this.gridView2.IndicatorWidth = 30;//设置显示行号的列宽

（2）设置动作gridView2.CustomDrawRowIndicator += new DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventHandler(gridView2_CustomDrawRowIndicator);

//添加行号

void gridView2_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)

{

if(e.Info.IsRowIndicator && e.RowHandle >= 0)

{

e.Info.DisplayText = (e.RowHandle + 1).ToString();

}

9.根据绑定的数据源自动产生列

gridView2.PopulateColumns();
