Avalonia Controls v25.2.0 Released

A major update for our Avalonia UI controls have been released that adds a new Docking/MDI control library with Visual Studio-like docking window and MDI functionality for your Avalonia apps, along with many updates to other products.  The Actipro Avalonia UI controls are a diverse set of UI controls, components, and themes for building beautiful Avalonia UI apps.

See our documentation's Getting Started section to learn how to download our open-source samples and take our Avalonia UI controls for a test drive.

Detailed Update List

Bars

• Added BarMainMenu control that can replace native Menu control.
• Added Tag property to all view models that can be used to store custom data.
• Added the RibbonViewModel.IsOptionsButtonVisible property.
• Added the RibbonBackstageViewModel.CanClose property.
• Added the RibbonBackstageViewModel.CanSelectFirstTabOnOpen property.
• Added the RibbonTabViewModel.IsEnabled property.
• Added the RibbonBackstageTabViewModel.IsEnabled property.
• Added a setter declaration to the IHasTag.Tag property.
• Updated BarComboBox to use weak event handlers for monitoring changes in the selected item.
• Updated editable BarComboBox controls with long text to scroll to the text start on focus loss.
• Updated a popup BarMenuItem whose key tip is accessed to focus its first child menu item.
• Updated RibbonTabHeader to match the IsEnabled state of the corresponding RibbonTab and render text using disabled brush when appropriate.
• Fixed an issue where RibbonBackstage might auto-select a first tab that was configured to not be visible.

Docking

• Added a new product consisting of a complete docking tool window and multiple document interface solution.
• End users can drag and dock windows wherever they please, and persist their layout customizations.
• Contains docking window and MDI capabilities found in popular IDEs, and extended functionality that you won't find anywhere else.
• Designed to fully support data-binding and use in MVVM applications.

Fundamentals

• Added WindowControl for simulating the look and feel of a Window with a Control.
• Added DialogChromedDecorations option for user prompts shown as a dialog that provides control over which parts of the dialog use custom chrome. The default appearance on Linux is greatly improved.
• Added UserPromptBuilder.CanResize and WithCanResize members that can pre-configure a User Prompt to be resizable.
• Updated User Prompt to use a WindowControl when showing prompts in overlay mode as this enables a prompt to be dragged to move. Prompts without a titlebar can be dragged by the header text or status icon.
• Updated BadgeAdorner ZIndex to be relative to the adorned element so overlapping badge adornments have a ZIndex consistent with the adorned elements.
• Fixed an issue where opening a new User Prompt without an explicit owner immediately after closing a window might throw an exception due to the closing window being used as the default owner.
• Fixed an issue where a User Prompt displayed with an owner that is on a mixed DPI monitor may not initially render correctly due to an Avalonia bug.

Themes

• Updated ThemeGenerator to generate immutable brush resources for optimal performance.
• Updated native ScrollBar thumbs to have a minimum size.
• Updated native control themes with changes in Avalonia through v11.3.0.
• Updated SliderThumb control theme to show an effect when pressed.

Shared Library

• Added a default context menu to ChromedTitleBar.
• Added built-in Icon support to ChromedTitleBar.
• Updated ChromedTitleBar to render caption buttons in different themes based on Windows, macOS, or Linux platform.
• Updated ChromedTitleBar to support extending into the macOS Window title bar area.
• Updated ChromedTitleBar to a base primitive control with a new WindowTitleBar derived control for when Window integration is desired.
• Updated WindowTitleBar to support Windows non-client hit-testing that is new with Avalonia 11.3.0. Notably, this adds support for Snap Guides when hovering over the Maximize button.

All

• Updated the minimum Avalonia UI dependency from v11.2.0 to v11.3.0.
