DevExpress Reporting Versionen

Accessibility Enhancements

• PDF/UA-2 Format Support
  • The PDF export engine now supports the PDF/UA-2 format (for enhanced accessibility compliance). You can specify PDF/UA-2 conformance for exported documents to meet the latest accessibility standards. Set the PdfExportOptions.PdfUACompatibility property to PdfUA2 to specify PDF/UA-2 conformance for exported documents.
• PDF/UA Export Enhancements
  • DevExpress improved PDF/UA export for report controls and screen reader interpretation. You can now define semantic roles for XRPageInfo, XRRichText, and XRPanel elements and supply accessible descriptions for digital signatures.
• XRPageInfo
  • Use the AccessibleRole property to define how screen readers interpret XRPageInfo content.
• XRPanel
  • You can reduce unnecessary noise in the accessibility tree with the AccessibleRole property.
• XRRichText
  • XRRichText content can now be exported as accessible (tagged) PDFs. The export process preserves semantic structure and reading order and improves compatibility with screen readers.
• Digital Signature - Accessible Description
  • You can specify accessible descriptions for the XRPdfSignature control when it is used as a digital signature or as a placeholder.

Report Designer for JetBrains Rider

• .NET Projects Support
  • In v25.2, DevExpress introduced the DevExpress Report Designer for JetBrains Rider with .NET Framework support. With v26.1, DevExpress extended this integration to .NET-based projects and reset in the Properties panel, along with light/dark theme support to match the JetBrains Rider IDE.

AI-powered Extensions

• Report Designer for WPF - Create Expressions with Natural Language
  • The WPF Report Designer allows users to generate AI-powered Criteria Language expressions within both the DevExpress Expression Editor and Filter String Editor. Users can describe the desired logic in plain text instead of writing complex expressions.
• AI Prompt-to-Report Wizard - Optimized Report Generation
  • To optimize the report generation process, DevExpress added a multi-agent system for the DevExpress AI Report Wizard (introduced in v25.1). This architecture improves result quality, consistency, and predictability, reduces token usage, and scales better for high-volume scenarios. The Report Wizard can generate complete reports from natural language prompts without detailed descriptions of report structure, controls, bindings, or calculations.
• AI Prompt-to-Report Cross-Platform API
  • The new AI APIs allow you to incorporate an AI-powered report generation engine into agentic workflows. Use it across desktop, web, and service applications and integrate with any AI provider via IChatClient.

AI-assisted Development

• AI Agent Skills for DevExpress Reports
  • DevExpress AI Agent Skills equip AI coding assistants with accurate, built-in knowledge of DevExpress Reports features up to v26.1. Instead of relying on general training data that produces incorrect APIs or outdated patterns, your assistant receives authoritative, scenario-focused guidance for reporting stack areas you use most.
• Custom GitHub Copilot Agent - DevExpress Report Designer
  • DevExpress created an *.agent.md file that gives GitHub Copilot in Visual Studio and JetBrains Rider DevExpress Reports-specific context. The file includes API patterns, expression syntax rules, common report design examples, troubleshooting guidance, and best practices. Developers who use GitHub Copilot in Visual Studio can get more accurate, context-aware answers when they work with DevExpress Reports.
