Hi everyone,
I’m currently integrating the Telerik Web Report Designer into an ASP.NET Core application and ran into an issue when trying to preview reports.
Setup:
- Telerik Reporting Version: 2025 Q1
- .NET Version: .NET 8
- Integration method: manual DLL references (no NuGet packages)
- Hosting: ASP.NET Core (Kestrel)
Problem:
The Web Report Designer itself loads correctly. I am able to browse reports, open .trdp files and modify them without any issues. However, when I try to preview a report, I consistently get the following error:
“HTML5Interactive rendering format is not available.”
Any ideas?
