unable to get report parameters in Telerik.Reporting on ISS Server

[Esteban]

Hi.

I have a problem with Telerik Reporting.

Everything works fine when working under a Visual Studio instance, but when I make a deploy to my IIS Server it sends me the error that the parameters cannot be obtained. I install on my server Telerik Report Designer R2 2017 and Fiddler to catch the error.

Hi Esteban,

Thank you for providing the error. After reviewing it, I can see that there's a problem with the ReportSource Resolver.

The reason for this is the path for the reports is likely not defined correctly and the viewer can't find the reports in the folder that it's looking in.

Below are two articles that can be used as a reference on how to set up the ReportSource properly:

- Report Sources

- How to set up Report Source for the Report Viewer

I hope that this information helps solve the issue and if you have any further questions please don't hesitate to ask!
