8 操作：
9 1.GridView設計器“ClickHereToChangeView-ConvertTo-advBandedGridView”
10 2.GridControl設計器中Bands新增“基本信息”和“費率”兩個Band
11 3.GridControl設計器中Bands中ShowColumnsSelector並拖動“運雜費”“采購費”“優惠系數”“優惠系數”到各自的Bands
12 3.GridControl設計器中Bands拖動2個優惠系數分別到第二行
13 4.GridControl設計器中Columns修改“名稱”列rowcount屬性為2
14 5.GridControl設計器中Bands和Columns所有列的MinWidth=100
15 6.GridControl設計器中Bands和Columns所有列的AllowMove=false
16 7.GridControl設計器中Bands中AutoWidth的勾去掉

--Devexpress GridControl 統計技巧
View Code
1 比如對“數量”列進行統計，只要在GridControl的設計器中設置SummaryItem:
2 SummaryItem.DisplayFormat = "{0:f2}";
3 SummaryItem.FieldName = "數量";
4 SummaryItem.SummaryType = DevExpress.Data.SummaryItemType.Sum;
--Devexpress GridControl 公式使用技巧
View Code
1 1.GridControl設計器 //由於數據庫的列“合價”不能既有值又綁定公式，所以我們引入一個虛擬的列“小計”
2 SQL語句“select 單價,數量,合價 from 表名”
3 數據庫真實列“單價”“數量”“合價”，非真實列“小計”
4 其中“小計”UnboundExpression=[單價] * [數量]
5 其中“小計”Visible=False //隱藏該虛擬列
6 2.后台代碼 //把“小計”計算的值寫入“合價”單元格
7 private void gridView_CellValueChanged(object sender, CellValueChangedEventArgs e)
8 {
9 if (gridView.FocusedRowHandle >= 0)
10 {
11 if (e.Column.Caption.Equals("數量") || e.Column.Caption.Equals("單價"))
12 {
13 //設置結果值
14 gridView.SetRowCellValue(gridView.FocusedRowHandle, gridView.Columns["合價"], gridView.GetFocusedRowCellValue("小計").ToString());
15 }
16 }
