組件描述

PivotTable	使用戶連接到支持 OLE DB Provider for OLAP Services 8.0 或更高版的 OLAP 數據源上 (也可連接到 Excel 電子數據表單 和 SQL Server 、 Access 關系數據庫)。PivotTable 控件允許用戶對數據進行透視、分組、篩選和排序等操作。
Spreadsheet	提供電子數據表單用戶接口,包括重算引擎和擴展函數庫。
Chart	圖形化顯示來自某個綁定數據源、PivotTable 或 Spreadsheet 控件的數據。當 Chart 組件被綁定到 PivotTable 控件且用戶重新透視數據時能自動刷新。
DataSource	管理與后臺數據庫服務器的通訊。PivotTable 和 Spreadsheet 組件實際上能單獨連接到數據源，，不一定非得要 DataSource 組件。這是因為其 XML 數據可以直接包含 OLE DB 連接串。

成員描述

PivotTable	使用戶連接到支持 OLE DB Provider for OLAP Services 8.0 或更高版的 OLAP 數據源上 (也可連接到 Excel 電子數據表單 和 SQL Server 、 Access 關系數據庫)。PivotTable 控件允許用戶對數據進行透視、分組、篩選和排序等操作。
PivotView	表示 PivotTable 的一個特定視圖. 用于對 PivotTable 視圖中的行、列、標尺、格式化進行設置。
PivotDataAxis	包含與數據軸相關的方法和屬性
PivotResultColumnAxis	包含與列軸相關的方法和屬性
PivotResultRowAxis	包含與行軸相關的方法和屬性
PivotFieldSet	多維數據集中定義的字段集
PivotField	多維數據集中定義的字段
ChartSpace	使用戶連接到支持 OLE DB Provider for OLAP Services 8.0 或更高版的任何 OLAP 數據源上，(也可連接到 Excel 電子數據表單和 SQL Server、Access 關系數據庫)。ChartSpace 允許用戶圖形化顯示數據并且將控件綁定到一個已存在的 PivotTable 或 Spreadsheet。
ChCharts	ChChart 對象集合
ChChart	ChartSpace 中的單個圖表，一個ChartSpace 可容納多達64個圖表。

Figure 5 PivotTable Component's Programmatic Interface

成員類型描述

ActiveView	屬性	表示一個活動的 PivotTable 布局。該屬性返回一個 PivotView 對象。
ColumnAxis	屬性	表示列軸中的字段。返回一個 PivotAxis 對象。
ConnectionString	屬性	設置連接到 Analysis Services 服務器的連接字符串，ConnectionString 屬性中的 DataSource 參數決定了 OWC 組件將要使用的連接協議。
DataAxis	屬性	表示數據軸的規模。返回一個 PivotAxis 對象。
DataMember	屬性	設置控件將要從 Analysis Services 請求的數據源名稱。它與多維數據集同名。
IncludedMembers	屬性	定義了 PivotField 內的數據成員。該屬性接受的參數為單一成員或成員數組。
IsIncluded	屬性	設置所包含的字段并激活 PivotFieldSet。
RowAxis	屬性	表示行軸中的字段，返回 PivotAxis 對象。
XMLData	屬性	設置或返回當前用于 PivotTable 報表控件的 XML 數據。有關報表的細節 (格式和數據) 均保存在 XML 數據中。也包括了 OLAP 連接詳細信息。
AddCustomGroupField	方法	為指定的 PivotFieldSet 添加一個定制的分組字段。
AddCustomGroupMember	方法	為指定的 PivotFieldSet 添加一個定制的分組成員。
InsertFieldSet	方法	在行或列軸中插入一個字段集。
CommandExecute	事件	在某個命令執行之后觸發，ChartCommandIdEnum 和PivotCommandId 常量包含用于每個 OWC 組件所支持的命令清單。
Query	事件	PivotTable 激活某個查詢時觸發。

Figure 6 Chart Component's Programmatic Interface

成員類型描述

DataSource	屬性	為 Chart 控件定義數據源。當設置另一個控件（如：PivotTable 或 Spreadsheet）這樣有效地綁定 Chart 控件到其它控件。
Type	屬性	象 ChartChartTypeEnum 枚舉所定義的那樣定義圖表類型，默認類型為條形圖。
