--Devexpress GridControl AdvBandedGridView 数据多行显示
1 实现效果：
2 |基本信息| 费率 |
3 | 名称 | 运杂费 |采购费 |
4 | |优惠系数|优惠系数|
5 | 第1段 | 2.2% | 1.0% |
6 | | 80% |90% |
7
8 操作：
9 1.GridView设计器“ClickHereToChangeView-ConvertTo-advBandedGridView”
10 2.GridControl设计器中Bands新增“基本信息”和“费率”两个Band
11 3.GridControl设计器中Bands中ShowColumnsSelector并拖动“运杂费”“采购费”“优惠系数”“优惠系数”到各自的Bands
12 3.GridControl设计器中Bands拖动2个优惠系数分别到第二行
13 4.GridControl设计器中Columns修改“名称”列rowcount属性为2
14 5.GridControl设计器中Bands和Columns所有列的MinWidth=100
15 6.GridControl设计器中Bands和Columns所有列的AllowMove=false
16 7.GridControl设计器中Bands中AutoWidth的勾去掉
--Devexpress GridControl RepositoryItemComboBox 只读
1 GridControl 的RepositoryItemComboBox 控件，如果需要设置“只读+下拉”方法如下：
2 GridControl设计器-Columns-某字段-Column properties-ColumnEdit-TextEditStyle=DisableTextEditor
--Devexpress GridControl 统计技巧
1 比如对“数量”列进行统计，只要在GridControl的设计器中设置SummaryItem:
2 SummaryItem.DisplayFormat = "{0:f2}";3 SummaryItem.FieldName = "数量";
4 SummaryItem.SummaryType = DevExpress.Data.SummaryItemType.Sum;
--Devexpress GridControl 公式使用技巧
1 1.GridControl设计器 //由于数据库的列“合价”不能既有值又绑定公式，所以我们引入一个虚拟的列“小计”
2 SQL语句“select 单价,数量,合价 from 表名”
3 数据库真实列“单价”“数量”“合价”，非真实列“小计”
4 其中“小计”UnboundExpression=[单价] * [数量]
5 其中“小计”Visible=False //隐藏该虚拟列
6 2.后台代码 //把“小计”计算的值写入“合价”单元格
7 private void gridView_CellValueChanged(object sender, CellValueChangedEventArgs e)
8 {9 if (gridView.FocusedRowHandle >= 0)
10 {11 if (e.Column.Caption.Equals("数量") || e.Column.Caption.Equals("单价"))12 {13 //设置结果值
14 gridView.SetRowCellValue(gridView.FocusedRowHandle, gridView.Columns["合价"], gridView.GetFocusedRowCellValue("小计").ToString());15 }
16 }
17 }
--Devexpress GridControl 屏蔽右键
1 optionmenu-》enablegrouppanelmenu类似参数为false
--Devexpress GridControl 全选
1.如图添加DevExpress.XtraEditors.CheckEdit，设置Size（18, 19）
2.设置GridControl首列“check”属性MinWidth，MaxWidth为20
3.添加代码
1 private void checkBox_All_CheckStateChanged(object sender, EventArgs e)
2 {
3 foreach (DataRow dr in dt_EvaluateProjectT.Rows)
4 dr["check"]=(sender as DevExpress.XtraEditors.CheckEdit).CheckState;
5 }
