Hi, i'n trying to show a report that i created using the report designer tool, but when i add it to the report viewer i get the error:
The data source 'testeds' uses a custom data processing WebAPI extension which cannot be null or empty. Please use a valid relative or absolute data extension.
Also i can't bind the path on xaml, ReportPath="{Binding RelatorioLivrosExcluidos}"(it doesn't find the report), but on code behind it works.
