一. 控件說明: XtraPivotGridControl；數(shù)據(jù)控件

?

?

二. 控件特點:

1. 支持行, 列字段拖動, 對調(diào)

?? 支持行, 列字段的添加, 移除

?? 支持?jǐn)?shù)據(jù)字段的添加, 移除, 對調(diào)

2. 支持以行, 列字段排序

??支持以過濾字段排序

3. 支持行, 列字段過濾??????????????????????????????????????????

4. 支持行, 列字段的歸類, 即形成父子層

橫向和豎向同時形成樹結(jié)構(gòu), 可收縮展開

?

三.測試數(shù)據(jù): 1.數(shù)據(jù)庫: sqlserver2000; Norwind

???? 2.關(guān)聯(lián)表: Customers; Orders; Order_Details; Products;

???? 3.DevExpress 版本: V8.1

?

四. 運行截圖:

1.?????? 行字段: 客戶名稱；訂單號

列字段: 產(chǎn)品名稱

數(shù)據(jù)字段: 商品單價；購買數(shù)量

過濾字段: 客戶公司名稱；所簽合同名；訂購日期；截止日期；提貨日期

?

?2. 以客戶名稱進(jìn)行過濾

?

3.?? 拖動行字段和列字段(此處演示對調(diào))

產(chǎn)品名稱作為行, 客戶名稱作為列顯示

同時將過濾區(qū)的字段 訂購日期作加入列中

這樣重構(gòu)樹: 客戶名稱à訂購日期

數(shù)據(jù)字段移除商品單價, 只保留購買數(shù)量

?

?

五. 程序代碼

1. 此處全部以 RunTime 進(jìn)行設(shè)計

2. 綁定數(shù)據(jù)源:

(1):selectSql:

?this.sqlstr = "select a.*, b.*, c.*, d.* from Orders a inner join Order_Details b on a.OrderID=b.OrderID "

+ " inner join Customers c on a.CustomerID=c.CustomerID inner join Products d on b.ProductID=d.ProductID;";

(2): DataSource ; DataMember;

this.pivotGridControl1.DataSource = this.database.RunReturnDataSet(this.sqlstr);

this.pivotGridControl1.DataMember = this.database.dataSet.Tables[0].TableName;

3.????? 運行時添加字段

子逸制作--動態(tài)添加字段
/// <summary>
/// 給消費鏈添加添加字段
/// </summary>
private void AddOrdersColumns()
{
//Customers表
PivotGridField customerID = new PivotGridField();
customerID.FieldName = "CustomerID";
customerID.Caption = "客戶名稱";
customerID.Area = DevExpress.XtraPivotGrid.PivotArea.RowArea;

PivotGridField companyName = new PivotGridField();
companyName.FieldName = "CompanyName";
companyName.Caption = "客戶公司名稱";
companyName.Area = DevExpress.XtraPivotGrid.PivotArea.FilterArea;
companyName.Width = 150;

PivotGridField contactTitle = new PivotGridField();
contactTitle.FieldName = "ContactTitle";
contactTitle.Caption = "所簽合同名";
contactTitle.Area = DevExpress.XtraPivotGrid.PivotArea.FilterArea;


//Orders表
PivotGridField orderID = new PivotGridField();
orderID.FieldName = "OrderID";
orderID.Caption = "訂單號";
orderID.Area = DevExpress.XtraPivotGrid.PivotArea.RowArea;

PivotGridField orderDate = new PivotGridField();
orderDate.FieldName = "OrderDate";
orderDate.Caption = "訂購日期";
orderDate.Area = DevExpress.XtraPivotGrid.PivotArea.FilterArea;

PivotGridField requiredDate = new PivotGridField();
requiredDate.FieldName = "RequiredDate";
requiredDate.Caption = "截止日期";
requiredDate.Area = DevExpress.XtraPivotGrid.PivotArea.FilterArea;

PivotGridField shippedDate = new PivotGridField();
shippedDate.FieldName = "ShippedDate";
shippedDate.Caption = "提貨日期";
shippedDate.Area = DevExpress.XtraPivotGrid.PivotArea.FilterArea;

//OrderDetails
PivotGridField unitPrice = new PivotGridField();
unitPrice.FieldName = "UnitPrice";
unitPrice.Caption = "商品單價";
unitPrice.Area = DevExpress.XtraPivotGrid.PivotArea.DataArea;


PivotGridField Quantity = new PivotGridField();
Quantity.FieldName = "Quantity";
Quantity.Caption = "購買數(shù)量";
Quantity.Area = DevExpress.XtraPivotGrid.PivotArea.DataArea;


//Product表
PivotGridField productName = new PivotGridField();
productName.FieldName = "ProductName";
productName.Caption = "產(chǎn)品名稱";
productName.Area = DevExpress.XtraPivotGrid.PivotArea.ColumnArea;

//添加到控制中
this.pivotGridControl1.Fields.Add(customerID);
this.pivotGridControl1.Fields.Add(companyName);
this.pivotGridControl1.Fields.Add(contactTitle);

this.pivotGridControl1.Fields.Add(orderID);

this.pivotGridControl1.Fields.Add(orderDate);
this.pivotGridControl1.Fields.Add(requiredDate);
this.pivotGridControl1.Fields.Add(shippedDate);

this.pivotGridControl1.Fields.Add(unitPrice);
this.pivotGridControl1.Fields.Add(Quantity);

this.pivotGridControl1.Fields.Add(productName);


}

?

2.????? 運行時改變字段的顯示區(qū)域

?

?customerID.Area = DevExpress.XtraPivotGrid.PivotArea.RowArea;

?

五. 屬性

1. 允許拖動

this.pivotGridControl1.OptionsCustomization.AllowDrag = true;

2. 允許排序

this.pivotGridControl1.OptionsCustomization.AllowSort = true;

3. 允許過濾

?this.pivotGridControl1.OptionsCustomization.AllowFilter = true;

?

六: 總結(jié)后記

1.????? 此控件較為靈活；對于 Master_Details 關(guān)系表處理的相當(dāng)好；

2.????? 此控件數(shù)據(jù)區(qū)只能顯示數(shù)字類型字段, 類似于統(tǒng)計分析；

3.????? 后面會有更多的 DevExpress 控件介紹給大家

4.????? 這里只介紹控件的簡單使用；如需更復(fù)雜的技術(shù)支持或交流請與作者聯(lián)系；
