水晶报表中的按需子报表

Question

I have a report where I am using an on-demand sub-report. But my user is viewing this report from a java application. So whenever he run the report he will view this report in PDF.

Report format:

country name         location            sales

<on-demand subreport>

Now once he run the report he will get all the above fields data in PDF format.

So now if clicked on location field data in PDF will he get the sub-report's data.

Answer 1

PDF isn't intended to generate dynamic content. As such, you'll need to find an approach that will render the desire content in a static manner.

I would suggest that you parameterize your report to display one of these options:

1. main only
2. main + subreport

The PDF will either contain the main report's content or the main and subreport's content.

** edit ** If you are using BusinessObjects Enterprise (BOE), you could use the openDocument API to generate a new report instance or the most-recently-generated instance. I don't know if Crystal Reports Server supports this feature for certain.

If you are rendering reports in a Java application, then you will need to a way to intercept the hyperlinks--a server, most likely. By in large, you'd be reinventing Crystal Reports Server/BOE.

Answer 2

Basically I understand as you need two thing.

1. you need to generate a report and export/generate in pdf.

2. in you need to attach link or something like editable field pdf.

For First answer, you can easily hide/show of sub-report in crystal report side. but not after report generate in pdf.

So for second answer, you need to pdf professional or editable allow version. after you get that you simply use itextsharp.dll (to generate pdf from asp.net-see below link).

So finally I think, does not needed crystal report.
