Feature: Telerik Reporting export feature
Error Message: "RendererNotAvailableException... rendering format is not available" for the following formats:
- DOCX
- HTML
- PPTX
- XPS
Code Snippet:
Telerik.Reporting.Processing.ReportProcessor reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();
Telerik.Reporting.Processing.RenderingResult result = reportProcessor.RenderReport(format, reportToExport, deviceInfo);
reportBytes = result.DocumentBytes;
if (reportBytes != null && reportBytes.Length > 0)
Mailer.SendNotifications(_report, reportBytes);
Solution:
As noted in the Deploying Applications using Telerik Reporting help section, the DOCX/PPTX/XLSX rendering extensions require Telerik.Reporting.OpenXmlRendering.dll and Open XML SDK 2.0 for Microsoft Office (DocumentFormat.OpenXml.dll v.2.0.5022.0 or above).
The XPS rendering extension requires Telerik.Reporting.XpsRendering assembly (Telerik.Reporting.XpsRendering.dll). In both cases your project should be targeting .NET 3.5 Framework or above.
If just adding the DocumentFormat.OpenXml.dll does not work, then, the
Open XML SDK 2.0 for Microsoft Office must be installed first on the server.
If still, it doesn't work, check the project that references to the project where Telerik Reporting is originally referenced. That project also needs the mentioned DLLs.
