在一个报告查看器 (rdlc) 中呈现多个报告 [英] Render multiple reports in one report viewer (rdlc)

问题描述

使用 ReportViewer 我想使用 rdlc 文件在一个 pdf 中呈现多个报告.

Using ReportViewer i want to render multiple reports in one pdf using rdlc file.

Byte pdfByte = Byte();
pdfByte = ReportViewer.LocalReport.Render("PDF", Nothing, mimeType, encoding, extensions, stream, warning);
Response.Clear();
Response.ContentType = mimeType;
Response.AddHeader("content-disposition", "attachment; filename=myfile." + extension);
Response.BinaryWrite(pdfByte);
Response.Flush();
Response.End();

这只会生成一份 pdf 报告.但我想在一个 pdf 文件中呈现多个报告.

This only generate only one report in pdf. But i want to get multiple reports rendered in one pdf file.

请帮帮我.

推荐答案

最简单的方法是将所有报表设计为一个主报表的子报表.然后，默认情况下，所有报告都将以一个 PDF 格式呈现.

The easiest way to do this would be to design all the reports to be sub-reports of one main report. Then, by default all reports will be rendered in one PDF.

这里有几个演示子报告的视频:第 1 部分&第 2 部分

There's a couple of videos demonstrating sub-reports here: Part 1 & Part 2

如果您无法将报告组织成子报告，那么 &坏消息...

If you can't structure your reports into sub-reports, then there is good & bad news...

坏消息:在框架中没有直接的方法来实现这一点.

Bad news: there's no straightforward way to achieve this in the framework.

好消息:可以使用 PDFsharp 3rd-party library.它是开源的免费使用，即使在商业应用中也是如此.

Good news: it's possible by using the PDFsharp 3rd-party library. It's open source & free to use, even in commercial applications.
