Bill Henning (Actipro)
Actipro Avalonia Controls v26.1 is here, and it is one of our biggest updates yet. The headline is the new Data Visualization product, which introduces a comprehensive barcode generation feature set for modern Avalonia apps, from branded QR experiences to production-ready linear codes used in retail, logistics, and packaging. Alongside that major addition, v26.1 also delivers meaningful enhancements across Bars, Docking/MDI, Fundamentals, Themes, and Shared, making the entire suite more capable, polished, and ready for real-world application workflows. Other key updates include Avalonia v12 compatibility and .NET 8 and .NET 10 support.
See the related announcement post for the detailed list of enhancements and updates.
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.
