通过 Web 正确渲染，但在使用 WinForms ReportViewer 时渲染时不计算表达式

Question

我遇到一个问题，在 SSRS 2005 上运行的 .RDL 报告（远程处理）将在通​​过 Web 浏览器查看时使用评估的表达式进行渲染：

http://my-server/ReportServer/Pages/ReportViewer.aspx?/Group%20Reports/Report_Lines&rs:Command=Render

但是，当在 C# 应用程序中运行时（通过 Microsoft.Reporting.WinForms.ReportViewer 控件），似乎报表呈现时无需评估报表中内置的表达式。

需要注意的一些事情：

• myReportViewer.ProcessingMode = Microsoft.Reporting.WinForms.ProcessingMode.Remote;
• 这些表达式通常具有条件格式性质 - 颜色变化取决于值等。
• 据我所知（我花了几个小时谷歌搜索/MSDN/查看这里等）问题在于在服务器端运行表达式 eval 时的信任/凭据。

另外，调用报告时 ReportServer__06_07_2011_07_57_20.log 中的差异：

基本上，我很乐意去日志拖网以获取更多信息 - 但我不知道在哪里查看。

有人告诉我下一步该去哪里吗？

tl;dr: Winforms.ReportViewer 不计算表达式，而 Webforms.ReportViewer 计算表达式。
