Good evening in advance thank you very much for any contribution, I'm doing a project and at the time of making the reports I stumble with Npgsql not link to the ReportViewer any suggestions? or maybe a editor of reports defirentes to VS as a report manager but still connect with Npgsql
Is that you do not need to link anything from Npgsql to ReportViewer
If you have created a local report .rdlc you must link this to a data source, which can be a datatable or list based on the type you define.
This example
How to create local reports RDLC featuring barcode images in ASP.NET
is very complete. There you will see that you can connect the report to a dataset or to a Custom Objects
The idea is that you use ado.net in a traditional way with the Npgsql libraries to load the object that you then assign to the report to link it to data
