Infragistics Professional Lanzamientos

• IgniteUI.Blazor
  • Added axis visibility properties to Axis and all XYChart-derived charts, allowing individual axis elements to be toggled without style overrides:
    • AreLabelsVisible - Hides the tick label text while the label panel keeps its layout slot.
    • AreTickMarksVisible - Hides the tick mark strokes.
    • AreAnnotationsVisible - Hides axis annotations (e.g. FinalValueLayer badges).
    • IsLabelPanelVisible - Collapses the entire label panel to zero extent.
    • The corresponding chart-level forwarding properties XAxisAreLabelsVisible, XAxisAreTickMarksVisible, XAxisAreAnnotationsVisible, XAxisIsLabelPanelVisible, YAxisAreLabelsVisible, YAxisAreTickMarksVisible, YAxisAreAnnotationsVisible and YAxisIsLabelPanelVisible were added on IgbCategoryChart, IgbFinancialChart and other XYChart-derived charts.
  • Added LegendItemBadgeMarkerSizeScaling to series, which controls how legend badges scale with the series MarkerSize. Supported values are Auto (default, interpolates the badge between 1x and 2x), None (badge keeps its default size) and Linear (badge scales directly with MarkerSize). The resolved sizes are exposed through the read-only ActualLegendItemBadgeMarkerWidth and ActualLegendItemBadgeMarkerHeight properties.
  • Added StartInset and EndInset to IgbLinearGraphRange (used by IgbLinearGauge and IgbBulletGraph) and to IgbRadialGaugeRange. The properties trim a range's start and end edges inward by a distance measured in device-independent pixels, producing a consistent gap between adjacent ranges regardless of the gauge's size or value range. Both default to 0, so ranges continue to meet flush unless an inset is set.
• IgniteUI.Blazor (Grids)
  • Updated the internal Ignite UI for Angular reference from 21.2 to 22.0, refreshing the generated models for IgbGrid, IgbTreeGrid, IgbHierarchicalGrid and IgbRowIsland, including the new GridBase, HierarchicalGridBase and RowIslandBase shared surfaces.

• IgbInput and other web inputs - Components were not registered on load; defineAllComponents registration was restored.
• IgbGrid - Filtering event detail payload now uses FilteringExpressionsTree instead of the previous incorrect type.
• Web inputs - ReportValidity and CheckValidity returned the wrong type on IgbCheckbox, IgbCombo, IgbDatePicker, IgbDateRangePicker, IgbInput, IgbRating, IgbSelect, IgbSlider and IgbTextarea.
• Web inputs - Focus options were not marshalled correctly; they are now treated as a plain object.
• IgbChat and other web components - Enum-typed properties were not serialized correctly when passed through the renderer element.
• IgbRadialGauge, IgbLinearGauge, IgbBulletGraph - Null reference exception could occur in the gauges.
• IgbSpreadsheet - Horizontal lines were not displayed correctly, and SVG shapes shifted position as line thickness changed.
• IgbDataPieChart - SeriesPointerEnter did not reach handlers on hover, and aggregated-away buckets were incorrectly measured in the angular range.
• IgbDataPieChart - Slice layers showed the wrong image when a requested image changed before a prior image finished loading.
• IgbDataChart - Chart was not disposed correctly on destroy.

• General
  • Removed Hammer.js dependency
    • The hammerjs and @types/hammerjs peer dependencies have been removed. All touch gesture support (Carousel swipe, Navigation Drawer pan/swipe, List Item pan, Time Picker vertical scroll, Grid Cell double-tap on iOS) is now implemented with native Pointer Events / Touch Events APIs.
    • HammerGesturesManager and related types (HammerInput, HammerStatic, HammerManager, HammerOptions) are no longer exported from igniteui-angular/core.
    • The ng add schematic no longer prompts for, or installs, hammerjs.
    • If your application imported hammerjs solely for Ignite UI components, you can safely remove it from your package.json dependencies, angular.json scripts/polyfills, and any import 'hammerjs' statements.
  • igxList
    • igx-list-item no longer tracks touch gestures when neither allowLeftPanning nor allowRightPanning is enabled, so pressing an item no longer captures the pointer or suppresses the touch scrolling of the list. When panning is enabled, the gestures are processed outside of the Angular zone, which keeps continuous touch dragging of large (virtualized) lists smooth.

• Angular 22 compatibility - All Ignite UI for Angular components are now fully compatible with Angular 22.
• Standalone component support - Components can now be used directly in standalone Angular applications without NgModule. New provide() functions (e.g. provideIgxCategoryChart()) let you register component feature sets through bootstrapApplication() providers, and imperative register() functions are available for DI-free setups.
• Per-component entry points for improved tree-shaking - Each package now exposes named subpath entry points (e.g. import 'igniteui-angular-charts/category-chart') that register only the feature set you need. The root package import remains fully side-effect-free and tree-shakeable, so you only pay for the components you use. For DataChart, graduated entry points such as data-chart-category, data-chart-scatter, and data-chart-financial let you pull in individual series families without bundling the entire chart.

• DataChart - An error is thrown when destroying chart with a data tooltip layer.

• Form associated custom elements with external labels
  • External <label> associations are now resolved to the underlying native input of form-associated controls. Associating a label with IgcInput, IgcMaskInput, IgcTextarea, IgcDateTimeInput, IgcSelect, IgcCombo, IgcDatePicker, or IgcDateRangePicker - either through the for/id IDREF mechanism or by nesting the component inside the <label> - now correctly exposes the label to assistive technologies and focuses the inner input on label activation.
• AI-Assisted Development
  • Improved grid related skills.

• Tabs
• Prevent selected tab header from scrolling into view on initial render.

• IgbChat (Preview) - a chat component with messages, reactions, suggestions, and typing indicators.
• IgbSplitter - resizable two-pane layouts with collapse, keyboard support, and nesting.
• IgbHighlight - search and highlight text projected into the component.
• IgbDockManager - two-way Layout binding plus new pane and tab events (Dock Manager 2.1).
• Four Agent Skills - components, grids, theming, and design-to-view guidance for AI assistants.

• NET (Core) Only
  • Replaced BinaryFormatter with new custom Infragistics Serializer - this will be the default serializer for serialization. If the Microsoft Binary Formatter is enabled and your binary data is in the older format, the Microsoft Binary Formatter will still be used for deserialization.
• Breaking Change
  • The new custom serializer is forward compatible in regards to binary files generated with prior versions of the Ultimate UI for Windows Forms toolset. Files originally generated with the BinaryFormatter can still be read and deserialized using the new serializer. However, the BinaryFormatter used in prior versions does not have the ability to deserialize files generated in the new version
• New Chart Features
  • Range Bar Series - Added RangeBarSeries to UltraDataChart so you can render low-to-high ranges as horizontal bars by combining a CategoryYAxis with a NumericXAxis.
  • Added the Checkmark marker type to supported chart marker enumerations, including LegendItemBadgeShape.
  • Added a new MarkerSize property to chart series that support markers so you can set the marker width and height to an exact device-independent pixel size. Setting MarkerSize to NaN restores the default template-driven marker size, and the property also applies when using lightweight markers. BubbleSeries continues to use radius-based sizing, so MarkerSize does not override bubble radius values.

• Tree
  • UltraTree is looking for the Infragistics.Win.Design DLL in .NET Core.
• ToolbarsManager
  • When using inherited Forms, adding a new UltraTab does not serialize the UltraTab object.
• Schedule

  • High dpi with images do not scale properly.
  • Windows Narrator - Extra Text been added when reading Child Row band of the UltraGrid.
• ExplorerBar
  • [High DPI] - Image and Font scaling is very inconsistent and incorrect.

  • [Accessibility] [Screen Reader] - UltraCombo doesn't get read by reader with checkbox options.
• Editors
  • UltraComboEditor narrator doesn't read the selected value.
• DataChart
  • LegendHighlightingMode property does not work in Windows Forms.
• Combo

  • UltraTextEditor shows context menu on right-click edge when unfocused even when ContextMenu and ContextMenuStrip are disabled.
• AppStyling
  • Button styling is different in Visual Studio 2022 versus Visual Studio 2026 with Office2010Blue .isl.
• ToolbarsManager
  • Cannot add a Main Menu Bar type of toolbar.
• NumericEditor
  • UltraNumericEditor fires ValueChanged twice when SpinIncrement is set and in/decrementing with the keyboard.

• New Chart Features
• Range Bar Series - Added support for the RangeBarSeries, a new xamDataChart series type for rendering value ranges as horizontal bars. It is the bar-oriented counterpart to the RangeColumnSeries and uses a NumericXAxis together with a CategoryYAxis.
• Added MarkerSize property so you can set an exact width and height in device-independent pixels for markers on supported chart series and restore template sizing with 'NaN'.
• Added the Checkmark marker type for chart series markers and legend badges.

• DataChart
  • Regression issue with XamDataChart using ScatterLineSeries and custom label converter, throwing index out of range error.
• DonutChart
  • DonutChart is not showing the LegendItemBadgeTemplate when themes are applied.
• TileManager
  • XamTileManager displays no tiles when only last tile is in view and that tile is removed when using Vertical layout order.

  • TextEditor resizes slightly when entering edit mode.
• PropertyGrid
  • When using a ContentPresenter in an EditTemplate scrolling the property grid causes values to change.
• TextEditor
  • XamRichTextEditor incorrectly shows horizontal scrollbar for loaded RTF file.
• DataGrid
  • Grouping in DataGrid by Unbound field with CalculationSettings formula doesn't recalculate.
• TreeGrid

• Popover based components
  • Popover reposition jitter in position: sticky ancestors.
• Tile Manager
  • Text selection in Safari during drag operation.
  • Tile manager height collapse when a spanning tile is maximized.

• Theming
  • Added derived themes for the Grid and related internal components. When a parent component theme is included, its internal controls now derive their tokens from the parent theme colors, keeping nested buttons, icons, inputs, dropdowns, checkboxes, scrollbars, chips, and other helper components visually aligned. The derived themes are introduces for the following components:
    • Grid
    • Excel Filtering
    • Grid Toolbar
    • Paginator
    • Column Actions
    • Query Builder and Advanced Filtering Dialog
    • The derived themes are applied through the existing component theme mixins, so no additional mixin call is required. To style the whole IgxGrid, provide the $background, $foreground, and $accent-color properties to grid-theme() and include the generated theme with tokens(). The $foreground property is optional; when omitted, it is derived automatically as a contrast color for the background. Internal components inherit derived tokens from the parent component theme.
  • Breaking Changes
    • IgxInputGroupComponent, IgxSelectComponent, IgxDatePickerComponent, IgxDateRangePickerComponent, IgxTimePickerComponent
    • The default type has changed from line to box. The ng update migration automatically adds type="line" to existing instances that do not already have an explicit type binding to preserve their appearance.
  • Behavioral Changes
    • IgxCarouselComponent
      • Changed the default tab order of the component; focus now flows starting with the active slide indicator, navigation buttons, or the first focusable element in the active slide, whichever is available.
  • General
    • Touch Gestures (HammerJS) (optional)
      • HammerModule, previously exported from @angular/platform-browser, is no longer available in Angular 22. Touch gesture support (Slider, Drag & Drop, Carousel swipe, Navigation Drawer) is optional.
    • IgxSelectComponent
      • The default positioning strategy has changed from the internal overlap strategy to AutoPositionStrategy. The dropdown now opens below (or above, if there is not enough space) the input element, consistent with other connected components.
    • Added IgxSelectOverlapPositionStrategy - a new publicly exported strategy that preserves the previous behavior of aligning the selected item's text over the input text.

• AI-Assisted Development
  • Decreased token consumption of skills and improved migration skill from grid lite to premium offering.
• Snackbar, Toast
  • Abstracted container positioning property into a new type NotificationPositioning.

• Expansion Panel
• Line height for title and sub-title slots.

• Invoker Commands API - declarative --show, --hide, --toggle via command and commandFor props, no JavaScript wiring required.
• Platform Popover Upgrades - Nav Drawer moves to native Popover API; Snackbar and Toast gain top-layer positioning property.
• Date Range Picker inline editing - edit range value directly via a single input field.
• Nav Drawer overlay CSS part removed - target base::backdrop or --ig-overlay-background-color instead.
• Form controls: Enter key submits the associated form - IgrInput, IgrMaskInput, IgrDateTimeInput, IgrCheckbox, IgrRadio, IgrSwitch, IgrDatePicker, and IgrDateRangePicker now match native HTML form element behavior on Enter. No code changes required; review any custom Enter-key handlers that manually call form.submit() to avoid duplicate submissions.
• Input: date/time type theming - date, time, datetime-local, week, and month input types now receive full theming support and consistent floating label behavior across all supported themes.
• Localization: resource strings deprecated - the per-component resourceStrings interfaces for Calendar, Chat, Date Picker, and Date Range Picker are deprecated. Components now use igniteui-i18n resource keys. Provide a complete resource strings object rather than setting individual string properties.

• Button Group selected state border color mismatch in focused and hover states; Combo display value not restored when tabbing out in single-select mode with partial search text; Stepper step components now correctly receive context when connected to the DOM before their parent stepper.

• Date Range Picker
  • Added support for editing the date range value directly via a single input field.
• Nav Drawer
  • The drawer for non-relative positions are now implemented using the native Popover API, providing built-in modal semantics, focus trapping, and accessibility support.
  • Added keepOpenOnEscape property - prevents the drawer from closing when the user presses the Escape key (non-relative positions only).
  • Added igcClosing event - emitted just before the drawer is closed by user interaction. Cancelable.
  • Added igcClosed event - emitted just after the drawer is closed by user interaction.
  • The overlay CSS part has been removed. Users of the component can target the base part's ::backdrop pseudo-element, the --ig-overlay-background-color variable or use the theming package.
• Invoker Commands API
  • igc-button and igc-icon-button now support 'command' and 'commandfor' properties, enabling declarative control of target components without JavaScript.
  • igc-banner, igc-dialog, igc-nav-drawer, igc-snackbar, and igc-toast now respond to --show, --hide, and --toggle commands dispatched by an invoker button.
• Snackbar
  • Added positioning property (viewport | container). The component now renders as a popover in the browser top layer. Setting positioning to container anchors the component to its nearest visible ancestor instead of the viewport.
• Toast
  • Added positioning property (viewport | container). The component now renders as a popover in the browser top layer. Setting positioning to container anchors the component to its nearest visible ancestor instead of the viewport.

• Deprecated
  • Localization
    • The old resource string interfaces for Calendar, Chat, Date Picker, and Date Range Picker are deprecated. Components now use the new igniteui-i18n resource keys. Setting individual resourceStrings properties directly is no longer supported; provide a complete resource strings object instead.

• Internal library metadata issue.
• Button Group
  • Selected state border color mismatch in focused and hover states.
• Combo
  • Display value not restored correctly when tabbing out in single-select mode with a partial search text.

• Stepper
  • In horizontal orientation, the content area height can now be driven by the active step's content instead of always being sized to the tallest step. A new --body-grid-rows CSS custom property controls the internal row sizing of each step body - its default value of 1fr expands the body to fit its content, while setting it to 0fr collapses the body to zero height, enabling fully variable step heights.

• AI-Assisted Development
  • Updated and enhanced the library provided skills.
• Button group
  • Themes color alignment.
• Circular Progressbar
  • Unified track color CSS variable between progress bars.
• Chip
  • Wrap content inside a new part container and update styles.

AI-Assisted Development - Agent Skills

• Added structured knowledge files that teach AI coding assistants (GitHub Copilot, Cursor, Windsurf, Claude, JetBrains AI, etc.) how to work with Ignite UI for React. The skill files are included in the igniteui-react package and also live in the skills/ directory:
  • Components - Identify the right React components for a UI pattern, then install, import, and use them - JSX patterns, events, refs, forms, etc.
  • Customize-theme - Customize styling using CSS custom properties, Sass, and the theming system in React, including using Ignite UI Theming MCP server.
  • Optimize-bundle-size - Reduce bundle size with granular imports, tree-shaking, and lazy loading.
• These skills are automatically discovered when placed in the agent's skills path (e.g. .agents/skills or .claude/skills).

IgxOverlayService

• IgxOverlayService.createAbsoluteOverlaySettings - Added a new overload accepting useContainerStrategy?: boolean as the second parameter. When true, uses ContainerPositionStrategy; otherwise defaults to GlobalPositionStrategy. The previous overload accepting outlet?: IgxOverlayOutletDirective | ElementRef is still supported but deprecated.

IgxSnackbarComponent, IgxToastComponent

• Added a new positioning input property. When set to container, the components is displayed inside its nearest positioned ancestor in place of the now deprecated outlet property.

IgxCombo, IgxSimpleCombo

• Introduced the selectionChanged event for both components. The event is not cancelable and is emitted after the selection is committed and the component state is updated.
• Added disableClear input that allows hiding the clear button even when items are selected. Defaults to false.

IgxOverlayService

• Deprecation - The outlet property in OverlaySettings, IgxOverlayOutletDirective, and igxToggleOutlet input on IgxToggleActionDirective are deprecated and will be removed in a future version. As overlay service now integrates the HTML Popover API and prefers rendering content in place / in the top layer, significantly reducing the need for outlet containers, new code should rely on the default in-place / top-layer rendering behavior instead of custom outlet containers.

AI-Assisted Development - Copilot Skill: Generate from Image Design

• Added a new igniteui-angular-generate-from-image-design Copilot Skill that teaches AI coding assistants/agents (e.g., GitHub Copilot, Cursor, Windsurf, Claude, JetBrains AI, etc.) how to implement Angular application views directly from design images (screenshots, mockups, wireframes).
• The skill provides a structured workflow covering image analysis, component discovery via MCP tools (list_components, get_doc), theme generation (create_palette, create_theme, create_component_theme), layout implementation, and visual refinement (set_size, set_spacing, set_roundness).
• Includes reference files:
  • Component Mapping - Maps common UI patterns (dashboards, charts, forms, navigation, data display, gauges) to the most appropriate Ignite UI for Angular component with key properties and decision rules.
  • Gotchas - Documents known pitfalls, component-specific constraints, and corrective patterns to help AI agents avoid common implementation mistakes.

AI-Assisted Development - Copilot Skills improvements

• igniteui-angular-grids skill - Added a new sizing.md reference covering grid and column width/height inputs, percentage and auto sizing modes, column sizing (minWidth, maxWidth, * star-sizing, auto-fit), and cell spacing/density control.
• igniteui-angular-components skill - Corrected Financial Chart (IgxFinancialChartComponent) documentation: updated chartType enum values to Auto, Candle, Line, Bar, Column to match the actual FinancialChartType API.
• igniteui-angular-theming skill - Minor cleanup to remove stale internal contributing reference.

• Icon service
  • Browser Safari: Now uses a plain Map instance for synchronizing state between actors. Since Safari does not support extended Map instances, it is required to use a plain Map for message transfer.

• IgcDataPieChart
  • DataPieChart - missing styling properties for the Others Slice.
• IgcDataTooltipLayer
