Ignite UI for Angular 21.1.0 での更新項目

機能

IgxPdfExporterService

• Added customFont property to IgxPdfExporterOptions for Unicode character support in PDF exports. By default, the PDF exporter uses Helvetica, which only supports basic Latin characters. When exporting data containing non-Latin characters (Cyrillic, Chinese, Japanese, Arabic, Hebrew, special symbols, etc.), you can now provide a custom TrueType font (TTF) with the required character glyphs. Key features:
• Supports any TrueType font (TTF) provided as Base64-encoded data.
• Optional bold font variant for header styling.
• Automatic fallback to Helvetica if custom font loading fails.
• Works with all grid types (IgxGrid, IgxTreeGrid, IgxHierarchicalGrid, IgxPivotGrid).

IgxTooltipTarget

• Added new properties:
  • showTriggers - Which will show the tooltip. Expects a comma-separated string of different event triggers. Defaults to 'pointerenter'.
  • hideTriggers - Which will hide the tooltip. Expects a comma-separated string of different event triggers. Defaults to 'pointerleave' and 'click'.

IgxNavigationDrawer

• Integrated HTML Popover API to place overlay elements when not pinned in the top layer, eliminating z-index stacking issues.

IgxOverlayService

• Integrated HTML Popover API into the overlay service for improved z-index management and layering control.
• The overlay service now uses the Popover API to place overlay elements in the top layer, eliminating z-index stacking issues.
• Improved positioning accuracy for container-based overlays with fixed container bounds.

AI-Assisted Development - Copilot Skills

• Three consolidated Copilot Skills are now included in the repository to teach AI coding assistants/agents (e.g., GitHub Copilot, Cursor, Windsurf, Claude, JetBrains AI, etc.) how to work with Ignite UI for Angular:
  • Components - UI Components (form controls, layout, data display, feedback/overlays, directives - Input Group, Combo, Select, Date/Time Pickers, Calendar, Tabs, Stepper, Accordion, List, Card, Dialog, Snackbar, Button, Ripple, Tooltip, Drag and Drop, Layout Manager, Dock Manager and Charts (Area Chart, Bar Chart, Column Chart, Stock/Financial Chart, Pie Chart)).
  • Data Grids - Data Grids (grid type selection, column config, sorting, filtering, selection, editing, grouping, paging, remote data, state persistence, Tree Grid, Hierarchical Grid, Grid Lite, Pivot Grid).
  • Theming & Styling - Theming & Styling (includes MCP server setup for live theming tools).
• These skills are automatically discovered when placed in the agent's skills path (e.g. .claude/skills) and this release ships with an optional migration to add those to your project.

Added IgxGridLiteComponent wrapper around the igc-grid-lite Web Component (in Developer Preview)

• Available from the igniteui-angular/grids/lite entry point. The wrapper component adds Angular-friendly API with similar inputs, including two-way bindable sortingExpressions and filteringExpressions, Angular template-based cell and header rendering with declarative templates via the igxGridLiteCell and igxGridLiteHeader directives.

IgxGrid, IgxTreeGrid, IgxHierarchicalGrid, IgxPivotGrid

• Improved performance by dynamically adjusting the scroll throttle based on the data displayed in grid.

IgxCombo, IgxSimpleCombo

• Combo and Simple Combo now close the dropdown list and move the focus to the next focusable element on "Tab" press and clear the selection if the combo is collapsed on "Escape".

Localization (i18n)

• IgxActionStrip, IgxBanner, IgxCalendar, IgxCarousel, IgxChip, IgxCombo, IgxDatePicker, IgxDateRangePicker, IgxGrid, IgxTreeGrid, IgxHierarchicalGrid, IgxPivotGrid, IgxInputs, IgxList, IgxPaginator, IgxQueryBuilder, IgxTimePicker, IgxTree:
  • New Intl implementation for all currently supported components that format and render data like dates and numbers.
  • New localization implementation for the currently supported languages for all components that have resource strings in the currently supported languages.
  • New public localization API and package named igniteui-i18n-resources containing the new resources that are used in conjunction.
  • Added API to toggle off Angular's default formatting completely in favor of the new Intl implementation. Otherwise Intl will be used when a locale is not defined for Angular to use.
  • Old resources and API should still remain working and not experience any change in behavior, despite internally using the new localization as well.

不具合の修正

Breaking Changes

• igxForOf, igxGrid, igxTreeGrid, igxHierarchicalGrid, igxPivotGrid
• 'original' data array mutations (like adding/removing/moving records in the original array) are no longer detected automatically. Components need an array ref change for the change to be detected.
• IgxGridGroupByAreaComponent has moved from the grids/core to the grids/grid entry point. The ng update migration will prompt you to optionally migrate your imports to the new entry point.
