Telerik Reporting R1 2019 fails to load assembly DocumentFormat.OpenXml 2.7.2+

Environment

Product Version 13.0.19.116
Product ProgressĀ® TelerikĀ® Reporting

Description

If DocumentFormat.OpenXML version 2.7.2 or higher is referenced in an application, the OpenXML rendering extensions are not available in the report viewers or an exception is thrown when a report is being programmatically exported to any OpenXML format.

Note: The issue is fixed in internal build 13.0.19.118.

Solution

Remove the current OpenXML references:

  • DocumentFormat.OpenXml version 2.7.2 or higher
  • Telerik.Reporting.OpenXmlRendering.2.7.2.dll

Add references to the following assemblies:

  • DocumentFormat.OpenXml version prior to 2.7.2 (i.e. 2.0.5022.0 - 2.5.5631.0)
  • Telerik.Reporting.OpenXmlRendering.dll
