在报表管理器中看不到子报表
我一直在关注本教程（课程6) 为了构建和部署带有嵌入式子报表的示例报表，该子报表从父报表读取其参数值。 该子报表嵌入到报表表的一组行之一中，并且两者共享相同的数据源。 此外，详细信息行会显示为折叠状态，直到用户按下表中每组数据的 (+) 按钮。
当我在 Business Intelligence Development Studio（顺便说一句，SQL 2005 Express 版本）中预览该报告时，该报告效果很好，但是当我部署它并尝试在报告管理器中查看时，子报告未显示 。 并且，如果我按 (+) 按钮，则会出现以下消息：
尚未指定某些参数或凭据
有人知道我做错了什么吗？ 为什么它在 Visual Studio 中嵌入的报表查看器中可以完美运行，但在报表管理器 Web 应用程序中却不能？
提前致谢。
I've been following this tutorial (lesson 6) in order to build and deploy a sample report with an embedded subreport which reads its parameters' values from the parent report. This subreport is embedded in one of the group rows of the report's table, and both share the same datasource. Additionally, detail rows appear collapsed until the user presses the (+) button for each group of data in the table.
The report works great when I preview it at the Business Intelligence Development Studio (by the way, SQL 2005 Express edition) but when I deploy it and try to see in the Report Manager, the subreport is not shown. And, if I press the (+) button, the following message appears:
Some parameters or credentials have not been specified
Does anybody has the slightest idea of what I am doing wrong? Why does it works perfectly in the Report Viewer embedded in Visual Studio but not in the Report Manager web app?
Thanks in advance.

子报表是否使用与父报表相同的数据源？ 如果不是，请务必检查子报表的数据源以确保其正确。 检查报告管理器，而不是您的本地副本。
Does the subreport use the same Data Source as the parent report? If not, be sure to check the data source of the subreport to make sure it is correct. Check in Report Manager, not your local copy.
我开始认为这可能是浏览器的问题。 我目前正在使用 Internet Explorer 8 Beta，并且我还遇到了报告管理器的奇怪行为。 我尝试过使用 Google Chrome 和 Firefox 3，虽然导航不如我喜欢的那么流畅，但问题似乎已经解决。
I'm beginning to think this could be an issue with the browser. I'm currently using Internet Explorer 8 Beta and I'm also experiencing weird behavior from the Report Manager. I've tried with Google Chrome and Firefox 3 and, although the navigation is not as smooth as I like, the problem seems fixed.
当您使用 IE8 作为报表浏览器时会发生这种情况。 我遇到了同样的问题，当我在 chrome 上测试时它工作得很好。
it happens when you use IE8 as a report browser. I faced same issue and when I tested on chrome it worked fine .
这可能相关，也可能不相关，但我前段时间遇到了类似的问题（除了在我的情况下，报告是通过自定义网页访问的），结果我们有一个旧版本的报告查看器控件（版本随 Sql 2005 RTM 一起提供）。 升级到最新版本后问题就消失了。
This may or may not be related, but I had a similar problem some time ago (except that in my case the reports were accessed through a custom web page) and it turned out we had an older version of the report viewer control (the version that came with Sql 2005 RTM). After upgrading to the latest version the issue went away.
