我们在WinForms报表查看器中指定预览时使用低分辨率的图像，在网页激活打印时使用PDF格式预览。

We customized the preview by displaying low resolution image in WinForms report viewer and by using PDF preview when the printing is activated from a web page.

查看器的工具栏有很多图标，他们可以完成内容表格的显示，重新运行报表，导出数据，以多种格式导出报表以及客户端和服务器端打印等任务。

The Viewer toolbar has ICONS for displaying the table of contents, re-running the report, exporting data, exporting the report to another format, and client and server-side printing.
