使用单个报告查看器创建多个PDF报告 [英] Creating multiple PDF reports with a single report viewer

问题描述

在基于单个报告查看器创建多个PDF文档时，我需要帮助.

我的页面上有几个下拉字段，用于获取登录用户的所有可能值.基于选择，我有一个SqlDataSource，它获取所需的记录数据.我的报表查看器基于SqlDataSource.

目前，对于我需要的每个PDF文件布局，我都有一个不同的报表查看器. 数据是相同的，但是布局根据下拉选择而有所不同."

如何消除对多个报表查看器的需求，并基于if语句动态更改PDF布局.

非常感谢，

I need help in creating multiple PDF documents based on a single report viewer.

My page has a couple of dropdown fields that get all possible values for the person that is logged in. Based on the selections, I have a SqlDataSource that gets the needed record data. My report viewer is based on the SqlDataSource.

Currently, I have a different report viewer for every PDF file layout that I need. "The data is the same, but the layout differes based on the drop down selection."

How can I eliminate the need for multiple report viewers, and dynamically change the PDF layout based on an if statement.

Thank you very much,

Nasser Hamdan

推荐答案

假设您将PDF查看器留给客户端，则可以通过将mime类型更改为"application/pdf"将二进制pdf从虚拟页面转储到客户端. br/>

Assuming you leave PDF viewer to the client you can dump binary pdf from a dummy page to client by changing mime type to "application/pdf".

protected void Page_Load(object sender, EventArgs e)
{
Response.ContentType = "application/pdf";
// Fill data here with binay PDF supplied by reporter or create PDF here.
// You can check GET or POST parameters to decide what to report here.
Response.BinaryWrite( data );
}
