Limitations

The Bold Reports^® ASP.NET Core Report Writer has the following limitations for custom code, data sources, PDF fonts, Excel export and image formats.

Can I use custom code in the Report Writer?

Yes. The Report Writer supports custom code with additional settings, because the VBCodeProvider is not available in the .NET Core platform. Custom code in a report lets you include new custom constants, variables, functions, or subroutines. Use the following solution to use custom code with the Report Writer.

Which data sources does the Report Writer process for RDL reports?

For RDL reports, the Report Writer has built-in data source processing only for SQL data sources. For other data sources, create a custom data extension for data processing.

Which font does the Report Writer use in PDF exports?

Without custom fonts, the Report Writer generates PDF documents only with the TimesNewRoman font, because the .NET Core platform cannot get font details from the system environment to embed report fonts in a PDF document. To get the fonts used in the report, provide the report font details separately in the PDF options. See Add custom fonts to PDF document to resolve this problem.

How many rows and columns can a Report Writer Excel export have?

An Excel document exported by the Report Writer can have at most 1,048,576 rows and 16,384 columns. Microsoft Excel cannot create a document with more than 1,048,576 rows and 16,384 columns, so the Report Writer does not create Excel documents from reports above that size.

Which image formats does the Report Writer support in PDF export?

The ASP.NET Core Report Writer supports only PNG and JPEG format images in PDF export. The limitation comes from the Syncfusion.Pdf.Net.Core library.
