25.1.2 での更新項目

機能

• Added RibbonViewModel.SelectedItem property for the currently selected RibbonTabViewModel.
• Added an InvocationFocusBehavior property to most bar controls that determines how focus should be handled following the primary invocation of the control.
• Added DockableToolBarSerializerOptions.IsVisible flag to serializer/deserialize dockable toolbar visibility with layouts.
• Improved RibbonGallery keyboard navigation to better match Office behavior.
• Updated the DockableToolBarHost.MenuOpening event to be raised when opening the options menu of a floating DockableToolBar.
• Updated RibbonBackstageTabViewModel so the Content property will default to itself. This improves the default experience of configuring data templates for each tab and makes it easier to see when a data template is not currently configured.
• Improved the crispness of rendered rectangles.

不具合の修正

• Fixed an issue introduced in the previous build where XAML-defined ribbon gallery popups didn't render the implicit menu gallery correctly.
• Fixed an issue where galleries would incorrectly call the Execute method for preview events when RoutedCommand-based commands were used.
• Fixed an issue where in-ribbon galleries that were updated when their parent tab was not selected may not invalidate measurement.
• Fixed an issue restoring the location of a floating DockableToolBar in certain mixed DPI environments.
• Fixed an issue dragging a floating DockableToolBar in certain mixed DPI environments where the initial floating location would shift on mouse down.
• Fixed an issue where UserPromptBuilder would not properly size a user prompt if the startup location was configured as CenterOwner and the owner could not be resolved.
• Fixed an issue where an exception might be thrown when attempting to set UserPromptWindow.Title if the title could not be resolved.
