Developer Express, Inc. has released DevExpress VCL Controls 25.2 is includes updated VCL components for: data entry, charting, data analysis, navigation, layout, grids, scheduling, styling, reporting, printing and planning.



What's new in VCL Controls v25.2


RAD Studio 13 Support
VCL v25.2.1+ and v25.1.4+ officially support the most recent versions of RAD Studio (Delphi 13 and C++Builder 13 for both 32-bit and 64-bit compilers).
Support Deprecation: Delphi/C++Builder 10.3, 10.2, 10.1, 10.0
Embarcadero first released IDE version 10.0 a decade ago. With our most recent update (v25.2), our VCL libraries only support 10.4 Sydney and more recent versions of RAD Studio (11.3, 12.3, 13.vLast)

ExpressReports – Official Release
This update marks the official release of our AI-enabled VCL Reporting Platform (ExpressReports). New features/capabilities include:
- Subreport support
- Report Parameters
- UI Localization enhancements
- Unified VCL backend and enhanced Dependency Management
- Updated Demos and enhanced documentation

A Preview of the Business Intelligence Dashboard (ExpressDashboards)
Our Delphi/C++Builder product line now includes a new VCL BI Dashboard (aka ExpressDashboards). ExpressDashboards is available as a Community Technology Preview (CTP). Much like ExpressReports, DevExpress VCL Dashboard leverages our JavaScript Dashboard Designer and Viewer for native VCL apps (using modern web-based design capabilities via WebView and ASP.NET Core/JavaScript wrappers). All required .NET and JavaScript dependencies are embedded into a single self-contained EXE file. As such, you can use Delphi/C++Builder for many dashboard-specific customizations. You can display/design BI dashboards either in modal full-screen mode or as an embedded/ad-hoc control on a form. Database, file system, and other dashboard template storage options are supported.

Accessibility, UI Automation, and Keyboard Navigation
VCL v25.2 includes accessibility (A11Y) enhancements for the following DevExpress VCL UI components:
- VCL Data Grid: Added group row support and additional control over cell data announcement.
- VCL Tree List: Key navigation support, read-only, and partial data editing usage scenarios (without complex interactions).
- Most popular VCL Data Editors: Key usage scenarios for both in-place and standalone editors.

Artificial Intelligence (AI) Enhancements
v25.2 introduces AI-powered Smart Paste within the DevExpress VCL Data Grid and Layout Control. Smart Paste analyzes content and intelligently assigns correct values to appropriate layout fields or row cells (to transform traditional copy-and-paste operations):

SmartCore AI Component Pack Integration
As you know, Embarcadero released brand new SmartCore AI Components shipped through the GetIt package manager. At present, the SmartCore AI platform is under active development. Once SmartCore APIs reach a production-ready state, we will integrate them into our AI-powered commands for native VCL controls. In the meantime, review the following integrations:
- Smart/AI-powered menu commands for DevExpress VCL Text Editors, such as TcxMemo or TdxRichEditControl.
- Smart/AI-powered semantic search/filter for the DevExpress VCL Data Grid.
- AI-powered Smart Paste functionality for the DevExpress VCL Data Grid and Layout controls.

Easier SVG Assignment for Image Lists at Design Time
Since our v24.1 release, the DevExpress VCL Ribbon allows you to use a single image list for large and small SVG icons. VCL v25.2 adds this capability to the following components:
- TcxButton
- TcxImageComboBox/TcxDBImageComboBox
- TdxNavBar
You can now configure large/small SVG icon settings for these components using new SVGOptions properties:

NOTE: Existing apps and usage habits will remain unaffected.

PDF Viewer Content Rendering Enhancements
BlendImage Support
We introduced BlendImage functionality with Darken and Multiply blend modes (additional modes will be added at a later time). You can now combine two images using multiple blending techniques.
Enhanced Gradient Rendering
We enhanced gradient rendering for image-to-fill and fill-to-image usage scenarios.
Optimized Embedded File Handling in PDF
We fixed issues related to nested PDF file embedding (for example, when a PDF contains another PDF). Additionally, binary data processing is now significantly faster because the parser no longer needs to pre-read embedded PDF data.
JBIG2Image Mask Support
Added support for predefined image masks in the JBIG2Image decoder. With v25.2, the JBIG2Image decoder supports predefined image masks and ensures correct rendering of PDF images that use mask data.
ColorSpaceName Persistence
We improved ColorSpaceName handling during document save operations to guarantee accurate color rendering.
Advanced Printing Features
When printing non-AsImage content, you can now print semi-transparent images or images with masks directly onto the printer canvas.
Shading Enhancements
Masks and transformation matrices are now applied correctly to final image output.
PNG Decoder Performance
Thanks to our optimized PNG decoder, you can expect up to a 30x speed improvement in certain decoding scenarios. Overall rendering performance has increased by 2–5x across multiple document types.
Text Rendering in TextClip Mode
Documents can now display multi-colored text, apply text fill effects, and overlay images on text. ClearType and Antialiasing at low DPI improve text rendering quality (compared to traditional clipping for small font sizes).

Enhanced HighDPI Support, Stability, and Performance
Hundreds of Quality Fixes
We continue to focus our efforts on quality bug fixes, performance and usability enhancements (especially for High DPI-related scenarios and vector skins).
Faster Rendering of Vector Skin Elements
v25.2 introduces performance-related enhancements for VCL apps running on 4K and other high-resolution displays. We optimized caching algorithm used for SVG images (applies to all vector-based skins):
- Approximately 20% rendering speed gains for apps using WXI/WXI Compact skins. Up to 10% performance improvement for other vector skins.
- Up to 10-15% speed gain for UI element resize operations and reduced form flickering (especially noticeable with RibbonStatusBar-based forms).
- Up to 60% rendering speed gain for complex form layouts using multiple editors in different states (disabled, read-only, etc.).

Updated RAD Studio Palette Icons
We "refreshed" the component icons in the IDE toolbox to help you distinguish them easier.
