ReportViewer changing CultureInfo?

Question

I have created a windows form in .NET 4.0 which dynamically loads reports into a ReportViewer. However after certain reports are loaded my current threads culture info changes to "en-US" (System.Threading.Thread.CurrentThread.CurrentCulture). Is there any reason for this?

PS This seems to be happening after the report has rendered on the screen.

Answer 1

I have done some more digging and it is definately the ReportViewer rendering that is causing the problem. I have created a work around using the RenderingBegin and RenderingComplete events to store the curent culture and reapply it post render. Is there anything in a report that can cause the culture to change (it isn't happening on all reports and I'm yet to find an obvious reason)?

Answer 2

I've tried to repro this locally but haven't had any luck so far, can you provide a little more information about the reports that are causing the issue such as what kind of data regions are on the report (Chart, Gauge, Tablix ...). Also are you able to create an isolated repro of the issue?

Done some more digging and this issue only occurs on reports with a document map.

This has been fixed in the dll versions of Microsoft.ReportViewer that come with Visual Studio 2010, version 10.0.40219.329.

I've successfully reproduced the thread culture change error with the dlls version 10.0.30319.1. The offending call was to 

Microsoft.Reporting.WinForms.Render(renderExtension, null, out mimeType, out encoding, out extension, out streams, out warnings);

The dlls involved are:

Microsoft.ReportViewer.Common.dll

Microsoft.ReportViewer.DataVisualization.dll

Microsoft.ReportViewer.ProcessingObjectModel.dll

Microsoft.ReportViewer.WebForms.dll

Microsoft.ReportViewer.WinForms.dll

These were installed with the Microsoft Report Viewer 2010 redistributable, at some point, on the problem machine. So examine your references and the GAC, you might find the error there, or be sure to restore the old culture after rendering anything report related.
