ActiveReports 报表应用教程 (16)

ActiveReports 支持多种格式的报表导出，包括PDF、Excel、Word、RTF、HTML、Text、TIFF以及其它图片格式，用户可以将它们应用到Windows Forms、Web、WPF、Silverlight等应用系统中。

在专业版的 ActiveReports 里，对PDF格式的数据输出又有了增强功能。现在用户可以将不可见的数字签名或者可见的文字图案加入到报表里。通过多种属性对数字签名进行个性化设置， 用数字签名验证报表作者，还可通过Certification Level 来设定用户访问权限。用时间印章功能建立第三方授权版本。这些新功能完全和Adobe的新安全机制兼容。

本文以客户订单为例演示如何将 ActiveReports 报表导出为各种格式。

1、创建报表文件

在应用程序中创建一个名为 rptInvoice.rdlx 的 ActiveReports 报表文件，使用的项目模板为 ActiveReports 页面报表。

2、打开报表资源管理器，并按照以下信息创建报表数据源

名称：	NWind_CHS
类型：	Micorsoft OleDb Provider
OLE DB 提供程序：	Microsoft.Jet.OLEDB.4.0
服务器或文件名称：	Data\NWind_CHS.mdb

 

3、 添加数据集

在新建的 NWind_CHS 数据源上鼠标右键并选择添加数据集菜单项，添加以下两个数据集：

常规-名称：OrderDetails

查询-查询：

SELECT TOP 10 订单.订单ID, 订单.客户ID, 订单.订购日期, 产品.产品名称, 订单明细.数量, 订单明细.单价, 订单明细.折扣, 订单.货主城市, 订单.货主地址, 订单.货主名称, 订单.货主邮政编码, 客户.电话

FROM ((订单 INNER JOIN 订单明细 ON 订单.订单ID = 订单明细.订单ID) INNER JOIN 产品 ON 订单明细.产品ID = 产品.产品ID) INNER JOIN 客户 ON 订单.客户ID = 客户.客户ID

ORDER BY 订单.订购日期 DESC;

 

4、设计报表界面

4.1、选中报表文件，并设置以下属性：

常规-数据集名称：	OrderDetails
分组：	名称：FixedPage1_Group 表达式：=[订单ID]

 

4.2、从 VS 中将 Table 控件添加到报表设计界面，并按照以下列表设置相应属性：

表格	属性
DataSetname	OrderDetails
FixedSize	19cm*15.75cm
RepeatHeaderOnNewPage	True
RepeatToFill	True
单元格	属性
Cells[2,1]	Value：=RowNumber("Table1")
Cells[2,2]	Value：=Fields!产品名称.Value
Cells[2,3]	Value：=Fields!数量.Value
Cells[2,4]	Value：=Fields!单价.Value
Cells[2,5]	Value：=Fields!数量.Value * Fields!单价.Value
合计单元格	属性
TextBox38	Value：=Sum(Fields!数量.Value * Fields!单价.Value,"FixedPage1_Group")
TextBox42	Value：=ReportItems!TextBox38.Value * 0.17
TextBox39	Value：=ReportItems!TextBox38.Value + ReportItems!TextBox42.Value

 

最终设计界面如下：

5、添加报表导出功能
