Here’s a look at some of the new features.

Fundamentals

AnimatedTextPresenter

A changing dashboard value can be easy to miss when it simply switches from one number to another. AnimatedTextPresenter gives single-line text updates a smooth rolling or fading transition, making it a natural fit for metrics, counters, and status text.

Numeric values can roll like an odometer, with increasing and decreasing values moving in their respective directions. You can choose whether characters, words, or the whole line transition together, and optionally use temporary colors to emphasize numeric changes.

BorderBeam

BorderBeam surrounds content with a colorful animated border and soft inner illumination. Use it to highlight a status card, important input, or other surface while keeping its content interactive.

Choose a traveling beam or a pulsing effect, then adjust the colors, motion, and glow to suit your design. Its default palette adapts to light and dark themes, and the effect can be activated when a particular state needs attention.

More in This Release

Badge can now animate changes to string content when animation is enabled.

New ThemeStyleIncludes options let applications selectively load styles for individual Actipro products, and ModernTheme starts faster when native control themes are disabled.

The Shared Library also adds CanvasControl, a primitive for custom rendering and coordinated animation.

Explore both new Fundamentals controls in the Sample Browser to see how they can make changing information and important states clearer in your Avalonia apps.

Actipro WPF Controls v26.1 modernized the entire product suite with official Visual Studio 2026 and .NET 10 support, comprehensive nullable reference type annotations, and a new shared Core assembly.

Here’s a look at some of the new features.

Editors

RangeSlider

The new RangeSlider control provided a convenient way for users to select a range between two values.

Decimal Editors and Input Filtering

New DecimalEditBox and DecimalPicker controls provided native editing and selection for Decimal values, including integration support for DataGrid and Grids.

Most edit boxes also gained optional input filtering, while numeric editors added composite string format support for greater control over displayed values.

SyntaxEditor

Line Terminator Preservation

SyntaxEditor documents and snapshots retained the actual line terminators used by source text instead of normalizing them internally to LF. Text retrieval preserved those original line terminators by default, while new APIs made it easy to identify the inferred line terminator, determine whether line endings were uniform, or normalize a document when needed.

Performance and Editing Improvements

The internal document text storage mechanism was refactored to improve performance and reduce memory usage. Regular expression searches gained support for non-capturing groups, invalid patterns were clearly identified in the search overlay, and several core editing structures and APIs were refined.

Menu Customization and Bars

New MenuFactory and BarsMenuFactory APIs allowed applications to customize or replace contextual menus across Actipro products, including using Bars controls for a consistent menu experience. Popup-based Bars controls and their MVVM view models added PopupClosedCommand support, while standalone toolbars gained a spacer mode that made it easy to right-align items. High contrast rendering, QAT behavior, and several menu and toolbar interactions were also improved.

Docking/MDI

New methods and configurable key gestures made it easier to open tab, context, and tool window menus or customize their keyboard behavior. Mixed-DPI popup positioning, sizing, and scaling were improved, WindowControl resizing became more flexible, and the Escape key correctly canceled hosted floating-window drag operations.

Window Chrome and Themes

WindowChrome internals were simplified to use native window borders, eliminating jitter that could occur when resizing from the left or top edge. List controls also adopted a lower-contrast selected-item background so a wider range of foreground content remained clear and readable.

Modern Platform Support

All libraries added .NET 10 targets and official Visual Studio 2026 support.

Nullable reference type annotations were added throughout the libraries and samples, providing better compile-time feedback when Actipro controls were used in modern C# applications.

Core Assembly

The new Core assembly centralized fundamental classes used throughout the product suite, including observable object, disposable object, logging, weak event, and extension infrastructure. Applications using direct assembly references needed to add the Core assembly when upgrading.

Additional Improvements

Elsewhere, Shell controls gained automatic DPI image refreshes, the SyntaxEditor .NET Languages Add-on improved IntelliPrompt within top-level statements, and Shared added useful logical and visual tree extensions, new InfoBar and Card options, and a simpler licensing dialog. Because this major release introduced a new assembly and other API changes, customers should review the Converting to v26.1 documentation topic before upgrading.

Due to the new Core assembly being added and other API updates in this major release, please see the Converting to v26.1 documentation topic for upgrade details.

Here’s a look at some of the new features.

Data Visualization

Barcodes

Data Visualization brings a complete barcode toolbox with 15 built-in symbologies, including QR Code, Micro QR Code, Code 128, GS1-128, EAN-13, EAN-8, UPC-A, UPC-E, Interleaved 2 of 5, ITF-14, Code 39, Code 39 Extended, Code 93, Code 93 Extended, and Codabar. This breadth lets teams standardize on a single API surface while covering the broad set of barcode formats commonly needed across consumer, business, and industrial scenarios. It is designed to be both developer-friendly and flexible enough for demanding production use.

For teams focused on branding, v26.1 adds advanced QR Code and Micro QR Code appearance options such as module shape customization, finder pattern shape customization, primary and secondary accent brushes, and gradient brush support. These features let you produce visually distinctive codes while still preserving reliable scanning behavior. It is a strong balance between brand expression and practical usability.

Data integrity and scan reliability were also core goals. The release includes robust encoding and validation behavior across symbologies, including automatic check-digit calculation and verification where applicable, optional EAN and UPC supplements, configurable quiet zones, and error-correction controls for QR variants. For linear barcode scenarios, you can fine-tune bar height, minimum height-to-width ratio, bearer bars for supported formats, and value alignment modes to better match printing and scanning requirements.

Outside of Data Visualization, v26.1 continues the momentum from recent previews with valuable suite-wide updates.

Fundamentals

The new RangeSlider control elevates the Fundamentals suite with a sleek, modern way to select and fine‑tune numeric ranges.

Bars

We've added a StandaloneToolBarSeparatorMode setting to BarSeparator that allows separators to act as spacers, making it easy to introduce flexible gaps or right-align items in standalone toolbars.

With a single spacer separator, items after the spacer will be right-aligned. When using two spacer separators, three groups of items will be created:  left-aligned, center-aligned, and right-aligned. Use spacer separators to creatively position groups of items.

Themes

Dark Theme Appearance Customization

A new customization option now lets you dial in the darkness of the neutral color ramp in generated themes, making it easy to shape your dark theme anywhere from refined dark gray to rich, immersive black.

AvaloniaUI OÜ's Avalonia Pro Support

For Actipro Avalonia Pro customers, we’ve introduced support for overriding AvaloniaUI OÜ's Avalonia Pro theme resources, allowing their Markdown, TreeDataGrid, and VirtualKeyboard controls to visually blend seamlessly with Actipro themes.

Avalonia and .NET Updates

This release advances platform support by aligning dependencies with the recently-released Avalonia v12, with all control themes updated to support v12's new controls and features.

The NuGet package targets now include both .NET 8 and .NET 10. The result is a stronger foundation for teams planning new development as well as those modernizing existing applications.

Actipro Avalonia Controls v26.1 is built to help you deliver more capable interfaces, better user experiences, and faster implementation across your Avalonia projects.
