Hello,

I am trying to run the Telerik Report Viewer with a WinForms application along with Wine on Linux. The application runs correctly, but it gives the following error before showing me the Report Viewer (the attached image). Is there a way to fix it. Thanks in advance

error: culture is not supported, the parameter name eo is an invalid identifier

Hi Josue,

Generally, the report is globalized with the help of a System.Globalization.CultureInfo object. The error indicates that the culture code for Esperanto 'eo' is not valid. The culture code is supported in Windows 10.

The problem may be that the culture is not available in the environment where the application is running. You use Wine and the problem may be there. I am not sure whether Wine supports the 'eo' culture. You need to verify this.

Note also that you may use Telerik Reporting REST Service directly on Linux, without Wine. You may test to embed the Html5 Report Viewer in your application and host the service under Linux - see for example:
