reportviewer issue

Hi,

I have .net mvc project and it uses Reportviewer to generate some reports.

The reportviewer works fine locally, but when I publish it to Winhost it first gave me the following error.

"Local report processing requires FullTrust Code Access Security permissions, which is unavailable to the calling code. Grant the application FullTrust permissions or use ServerReport to execute the report remotely."

Then, I came to this forum and realized that I need to add a line of code into web.config to set the trust to full.

<configuration>
<system.web>
<trust level="Full" />
</system.web>
</configuration>

Then, it gave me a completely blank page. But there was a error message typically generated by reportviewer before the page completely got white-out. I can't capture that.

After this, I saw a post that I need to change HTTP Handler in IIS, so I added following handler

Request Path: Reserved.ReportViewerWebControl.axd
Type: Microsoft.Reporting.WebForms.HttpHandler
Name: ReportViewerWebControl

But, still it doesn't solve my problem.

Can anyone help me?

Thanks in advance/

 

I also added following files to bin:

1) Microsoft.ReportViewer.Common.dll
2) Microsoft.ReportViewer.WebForms
3) Microsoft.ReportViewer.WebForms.dll
4) Microsoft.ReportViewer.WinForms
5) Microsoft.ReportViewer.WinForms.dll
6) Microsoft.ReportViewer.ProcessingObjectModel.dll

all are version 10.

Still not solved my problem. T.T

 

Do you have a URL we can look at to replicate the problem on our end?

Report Viewer Configuration Error

The Report Viewer Web Control HTTP Handler has not been registered in the application's web.config file. Add <add verb="*" path="Reserved.ReportViewerWebControl.axd" type = "Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> to the system.web/httpHandlers section of the web.config file, or add <add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> to the system.webServer/handlers section for Internet Information Services 7 or later.

This is part of my web.config after connectionString

Hi, I have the same issue, did you find a solution?

 

That works, thanks. Actually I had full trust on before, but with a recent publish, it was accidentally removed, so started getting this error.
