Avalonia Controls v25.2.3 Release

A new update for our Avalonia UI controls have been released.

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

• Updated various buttons to not take focus when clicked if focus is currently outside of the ribbon.
• Updated button click handlers to perform InvocationFocusBehavior logic before processing the click.
• Fixed an issue introduced in the previous build where RibbonWindow.Padding was being applied twice.
• Fixed RibbonWindow showing chromed titlebar on Linux when the native titlebar was also displayed.

Docking

• Updated the background rendering of tinted tabs in light themes.
• Updated logic that handled AdvancedTabItem.IsSelected changes.
• Fixed an issue where previously selected tabs may not always be reselected during layout deserialization.
• Fixed an issue where altering DockingWindowsDragOverEventArgs.AllowedDockGuideKinds may not always show the proper dock guides.
• Fixed an issue where double-clicking a ToolWindow titlebar was not being properly recognized.

Fundamentals

• Updated resizable User Prompts with Full dialog chrome decorations to fallback to None on Linux since borders are required for resizing.
• Updated the UserPromptExtensions.ForException extension method to not configure the prompt as resizable on Linux due to restrictions with dialog chrome decorations.
• Fixed an issue where MultiColumnPanel was including invisible children in its layout calculations.

Themes

• Added a new theme resource for edit control placeholder font style.
• Updated the DataGrid theme to prevent the column header border from possibly disappearing when using star-sized columns.

Shared Library

• Updated WindowTitleBar to work around scenarios in Windows 10 where the Window border may disappear.
• Updated AnimatedExpanderDecorator to only animate when already loaded.
• Fixed an issue where turning a pointer wheel over a control's popup could cause an ancestor ScrollViewer to scroll.
• Fixed an issue where an extra OS-generated tooltip would display for the minimize and maximize caption buttons of WindowTitleBar on Windows OS.

Core Library

• Added the TrustedCodeService class that manages dynamic loading of types in a secure-by-default manner. This change may be potentially breaking for certain rarely used features, so it's important to review the related documentation for details.
