Our Blazor year-end roadmap for v26.2 is here, shipping December 2026. Key focus areas: right-to-left support, the official Icon Library release, and the first components for a new styling and layout foundation.

RTL Support (CTP): Right-to-left layout ships as a Community Technology Preview. Switch an entire application to RTL, build custom RTL UI blocks alongside components, or keep individual editors in LTR mode within an RTL app. Supported across Grid, TreeList, Charts, Pivot Table, Filter Builder, Data Editors, Form Layout, AI Chat, HTML Editor, and navigation/layout/popup components. Requires Fluent themes.

New Components: App Bar provides a top-level command strip with title area, hamburger button, search item, avatar dropdown, and built-in adaptivity. Side Bar adds a vertical, icon-based navigation strip inspired by Microsoft Office applications.

Icon Library (Official Release): Moving from CTP to production. IconUrl parameter added to Editor Buttons, Progress Bar, Toast, and Scheduler Forms. New flexible API lets you specify any combination of style, set, and size. 400+ new Fluent icon metaphors added.

CSS Variable Rework: Public --dxds-* variables get role-based names with broader coverage, preparing the design system for future themes like Material. The Project Converter handles automatic migration when upgrading to v26.2.

AI Chat: Built-in reasoning visualization so users can review a model's step-by-step thinking. Built-in tool approval visualization for human-in-the-loop actions (no custom template required). Pre-attached resources API for providing AI context at session start. New ClearHistoryAsync method. UI/UX refinements in Fluent themes.

Grid and TreeList: Filter Row criteria selector menu for choosing filter conditions inline. On-input filter binding that applies filters as users type. Built-in toolbar items for Column Chooser, Export Buttons, and Search Box. Continuous cell editing on Enter. Striped rows option. Custom row height setting.

Also in v26.2:
- NET 11 support
- Minimum .NET raised to .NET 10
- DateTimeOffset support across Blazor UI components with a global offset option
- Security SBOMs moving out of preview for CRA readiness
- TextBox password visibility button
- Form Layout caption position mode and tab management API
- Accessibility: App Bar and Side Bar ship with keyboard navigation, ARIA roles, and high-contrast mode

Our Office and PDF File API year-end roadmap for v26.2 is here, shipping December 2026. This release introduces new document processing libraries for .NET and Java, expands security capabilities, and adds significant new features to the PDF Document API.

New Document Processing Libraries: A new Word Processing Document API replaces the current interface-based API with a concrete, tree-like object model. Generate complete documents from scratch, apply styles, insert tables and images, run mail merge, search and edit with a range-based API, export to PDF, and convert across Word-like formats including HTML. Ships as a dedicated NuGet/JAR package. A new Spreadsheet Document API follows the same object-based design for workbook processing, covering formulas, charts, shapes, sorting, filtering, and PDF export. Both APIs target .NET and Java with the same feature set.

Safer Document Processing: PDF Document API adds secure loading and sanitization for untrusted documents. Set limits for file size, object count, and page count. Strip embedded JavaScript, document actions, and attachments. Sanitize external links, metadata, and annotations. Presentation API adds its own security layer with loading limits, dangerous content removal during import, and a privacy Inspect/Sanitize API for metadata, hidden slides, speaker notes, and embedded objects.

PDF Document API: Digital Signature API for signing, inspecting, and creating signature fields with full appearance customization. Bookmark API for document outline navigation. Form field and annotation flattening. PDF/A and PDF/UA compliance for generating, converting, and validating compliant documents. Built-in OCR for turning scanned pages into searchable, extractable, AI-ready text. Incremental update support in research for saving changes as revisions without rewriting the entire file.

Presentation API: Full hyperlink support for text runs and shapes, targeting web URLs, email addresses, local files, and other slides. Round-trips on import and export.

Word Document Processing: Floating-point layout calculation for more precise text and object positioning in PDF export, with closer compatibility to Microsoft Word rendering. PDF/UA-2 export enhancements with structure destinations and AcroForm field tagging for accessible PDF forms.

Spreadsheet Processing: ODS (OpenDocument Spreadsheet) format support in research, driven by rising public sector demand including Germany's Deutschland-Stack mandate for ODF alongside PDF/UA.

Our WPF year-end roadmap for v26.2 is here, shipping December 2026. Two major focus areas: a modern Fluent-based look and feel, and broader AI-assisted development capabilities.

Fluent Theme and Modern UI: New Fluent Theme (CTP) for the WPF Grid Control, Property Grid, Dock Layout Manager, ThemedWindow, and other major component libraries. ThemedWindow gets Mica material support so navigation controls and Ribbon tabs render transparently, matching the look of Microsoft Office apps. The Accordion Control ships with a modern appearance modeled on Microsoft Teams and Microsoft Store. A new global switch lets you apply the Fluent Icon set across all DevExpress WPF controls, backed by a library of 13,000+ icons organized by set, style, color, and size.

AI Chat Control: Built-in workflow visualization for multi-agent, multi-step processes with parallel steps, tool calls, and tool-approval requests. New AG-UI demos showing visualized tool-call results, interactive multi-step flows, human-in-the-loop actions, and interaction with view components outside the chat control. The control will also expose an API for appearance customization.

WPF Agent Skills: New AI agent skills for building DevExpress WPF apps with coding assistants like Claude Code and GitHub Copilot. Initial skill catalog covers appearance customization, UI Automation test creation, accessibility remediation, performance optimization, dependency injection integration, and MVVM Framework implementation.

Also in v26.2:

- .NET 11 support (both v26.1 and v26.2)
- Minimum .NET raised to .NET 10 (following .NET 8 and .NET 9 end of support in November 2026)
- Minimum IDE raised to Visual Studio 2022
- DateTimeOffset support in core controls with automatic time zone conversion
- Data Grid validation icon and separator customization
- Tree List indent highlighting
- Duplicate command for conditional formatting rules
- DXTabControl delayed tab caching for faster startup
- Security SBOMs extended to NPM packages and VCL libraries, moving out of preview

DevExpress just shipped 14 new WinForms Agent Skills and reviewed every existing skill for reliability.

Agent Skills teach AI coding assistants proven DevExpress implementation patterns so they generate accurate code on the first try. The big WinForms addition: each skill leads with the designer-file pattern, putting controls in *.Designer.cs via InitializeComponent() instead of constructor code. That means the Visual Studio designer surface stays intact for the next developer who opens the form.

New skills cover 14 controls and features: Accordion, AI Chat, Charts, Data Grid, Editors, Layout, Loading Indicators, MVVM, Pivot Grid, Property Grid, Ribbon and Bars, Scheduler, Tab Control, Tree List

Works with 6 assistants: GitHub Copilot (VS Code, Visual Studio 2026, CLI), Claude Code, Cursor, Codex CLI, JetBrains Junie, JetBrains AI Assistant

What else changed:

- Enhanced MCP Server fallback so assistants reliably check documentation when unsure of an API
- Refined elicitation so skills prompt you for missing details before generating code instead of guessing
- .NET 8 minimum verified for v26.1
- Accuracy fixes for Office File & PDF API and DevExpress - Reports skills
- Plugin installation added for Codex CLI and Cursor

If you use plugins, updates arrive automatically. If you copied skill folders into .github/skills/ or .claude/skills/, grab fresh copies from the DevExpress GitHub repository.

Try a skill and share feedback in the DevExpress Support Center. Flag wrong API calls, missed steps, anything you fixed manually. That feedback shaped this update and will shape the next one.

In this post, I'll summarize our most recent update including: 14 new WinForms skills, a repository-wide review of every skill we've shipped previously, and plugin installation for Codex CLI and Cursor.

WinForms Year-End Roadmap (v26.2) is now published. Here's what the DevExpress WinForms team plans to ship in December 2026:

• .NET 11 support in both v26.1 and v26.2, following Microsoft's official release.

• Minimum supported versions move to .NET 10 and Visual Studio 2022. .NET Framework 4.6.2 stays the minimum.

• Software Bills of Materials (SBOMs) leave preview and become available to every customer, covering NuGet, NPM, and VCL libraries. They help EU customers document DevExpress components for Cyber Resilience Act compliance.

• A global switch to use Fluent icons across all DevExpress WinForms controls, with design-time filtering by set, style, color, and size.

• AI coding skills for Claude Code and GitHub Copilot that teach AI agents DevExpress best practices for appearance customization, UI Automation tests, and designer file code structure.

• AI Chat Control updates: workflow visualization for multi-step agent processes and a set of AG-UI demos showing tool-call results, interactive flows, and human-in-the-loop approvals.

• Native DateTimeOffset support in Data Editors and the Data Grid. Values display in each user's local time zone, including in filters, sorting, grouping, and summaries.

• Server Mode over Web API: connect to ASP.NET Core endpoints without OData, using your own HTTP client and server-side row rules.

• Accordion Control compact mode: one design-time action turns a classic accordion into a Teams- or Outlook-style navigation panel.

• Complete built-in localizations for selected languages, starting with German.

• WinForms UI Templates move into the DevExpress Template Kit.
