A SQL Server technology that supports the creation, management, and delivery of both traditional, paper-oriented reports and interactive, web-based reports.
Hi @jkiel ,
a bit late, but it might still help.
One option that seems particularly aligned with your requirements is the reporting component List & Label from combit, which you can find on the Visual Studio Marketplace. It is designed specifically for this kind of application-embedded, paginated reporting scenario: you can integrate it into .NET applications and run reports from C#, while reports can be designed independently by users who don't need to know .NET. SQL Server is supported as a data source as well.
It also focuses strongly on the type of reports you mention—printable, precisely formatted documents such as picking lists, delivery notes/certificates, forms, labels, and similar outputs—rather than primarily being a dashboard/BI tool. That may make it a better fit for your use case than Power BI, while offering an alternative to SSRS and Telerik.
