Ignite UI for Angular 12.0.0 Release

Just in time for Angular 12, it’s Ignite UI 12.0.0!

 We are all excited about the release of Angular 12 and the new features that it supports. At Infragistics, we strive to provide you with the best possible user experience and keep you up-to-date with the latest versions of frameworks, platforms, and technology. That is why we are excited to share that we have released Ignite UI for Angular 12.0.0 , with full support for Angular 12, so quickly after its release!

To be the best Angular enterprise-grade library takes continues efforts and devotion. Ignite UI 12.0.0 is proof for that. We continue to add new components and features, enhance the existing ones and address your requests, letting you creating Angular application at ease. Let's see what do we have for you in Ignite UI 12.0.0:

Angular Components

 Angular Tree Component

 The Angular Tree Component allows users to represent hierarchical data in a tree-view structure, maintaining parent-child relationships, as well as to define static tree-view structure without a corresponding data model. Its primary purpose is to allow end-users to visualize and navigate within hierarchical data structures. The Ignite UI for Angular Tree Component also provides load on demand capabilities, item activation, bi-state and cascading selection of items through built-in checkboxes, built-in keyboard navigation and more.

 Angular Date Picker& Angular Time Picker Update

 As mentioned above, keeping the top position for enterprise-grade Angular library, obligates us to continuously improve our product. In Ignite UI 12.0.0 you can enjoy on enhanced user experience with updated Angular Date Picker and Angular Time Picker components. You can find more in Ignite UI documentation.

 Angular Date Time Editor

 We have added new feature to our Angular Date Time Editor. Now it accepts ISO 8601 date strings. Find more here.

Design & Theming

 Ignite UI for Angular would not be complete without our state-of-art design and theming. Ignite UI 12.0.0 comes with reduced themes size, global palette values and new "How to..." topics. Check out the updated "Styling & Themes" documentation.

 Reduced themes size

 Use of global palette values (CSS variables)

 Scope custom CSS properties to component selectors

 Expose elevations as custom CSS properties

 Typography to be explicitly set by the user

 New Bootstrap Theming Sample

Angular Grids: Grid, Tree Grid and Hierarchical Grid

 Export Angular Hierarchical Grid to Excel

 The Excel Exporter service now can export data to excel from the Ignite UI Angular Hierarchical Grid. The data export functionality is encapsulated in the IgxExcelExporterService class. To trigger the process, you need to invoke the IgxExcelExporterService's export method and pass the IgxHierarchicalGrid component as the first argument.

 Datetime & Time Column Types

 We add two new members to our Angular Column Data Types portfolio. The appearance of the date portions will be set (e.g. day, month, year) based on locale format or pipeArgs input. The pipe arguments can be used to specify a custom date format or timezone.

 Angular Tabs& Angular Bottom Navigation Refactoring

 Another two angular components that have been updated and changed in Ignite UI 12.0.0. 

 Expose API for a new row object in Angular Grid

 The Grid provides a convenient way to perform data manipulations through inline row adding and a powerful API for Angular CRUD operations. Add an Action Strip component with editing actions enabled in the grid's template, hover a row and use the provided button or press ALT + + to spawn the row adding UI.

Angular Grid Interactions

 Detach method for IgxOverlay

  • Features API for handling selection (bi-state and cascading), node activation, node expansion state.
  • Features extensive and easy-to-use keyboard navigation, fully compliant with W3 standards.
  • Code example for a tree contructured from a hierarchical data set:

  <igx-tree><igx-tree-node*ngFor="let node of data" [data]="node" [expanded]="isNodeExpanded(node)" [selected]="isNodeSelected(node)">
              {{ node.text }}
              <img[src]="node.image" alt="node.imageAlt" />

                  {{ child.text }}
                  <igx-tree-node*ngFor="let leafChild of child.children" [data]="leafChild" [expanded]="isNodeExpanded(leafChild)" [selected]="isNodeSelected(leafChild)"><aigxTreeNodeLinkhref="{{leafChild.location}}" target="_blank">{{ leafChild.text }}</a></igx-tree-node></igx-tree-node></igx-tree-node></igx-tree>

  • For more information, check out the README, specification and official documentation

• IgxHierarchicalGrid

  • Added support for exporting hierarchical data.

• IgxForOf, IgxGrid, IgxTreeGrid, IgxHierarchicalGrid

  • Behavioral Change - Virtual containers now scroll smoothly when using the mouse wheel(s) to scroll them horizontally or vertically. This behavior more closely resembles the scrolling behavior of non-virtualized containers in most modern browsers.

• IgxGrid, IgxTreeGrid, IgxHierarchicalGrid

  • The IgxRowAddTextDirective allows to customize the text of the row adding overlay.

    <igx-grid[rowEditable]="true"><ng-templateigxRowAddText>
                Adding Row
            </ng-template></igx-grid>

  • A new summaryFormatter input property is exposed by the IgxColumnComponent, which is used to format the displayed summary values for the columns.

    publicdateSummaryFormat(summary: IgxSummaryResult,summaryOperand: IgxSummaryOperand): string {constresult=summary.summaryResult;if(summaryOperandinstanceofIgxDateSummaryOperand&&summary.key!=='count'&&result!==null&&result!==undefined){constpipe=newDatePipe('en-US');returnpipe.transform(result,'MMM YYYY');}returnresult;}

    <igx-columnfield="OrderDate" header="Order Date" [sortable]="true" [disableHiding]="true" [dataType]="'date'" [hasSummary]="true"
            [summaryFormatter]="dateSummaryFormat"></igx-column>

  • Two new column types are introduced dateTime and time. In order to operate with them is necessary to set the column property dataType to 'dateTime' or 'time'.

    <igx-columnfield="OrderDate" header="Order Date"  [dataType]="'dateTime'" ></igx-column><igx-columnfield="ClosingTime" header="Closing time"  [dataType]="'time'" ></igx-column>

  • Behavioral Change - Column Autosize feature now does not handle templated headers where the first level children are sized based on parent like default div and etc. Autosizing for such headers will not result in change.

  • Behavioral Change - Calling autosize through the IgxColumnComponent API now takes into consideration the minWidth and maxWidth of the column.

  • A new IgxColumnComponent input property is exposed called autosizeHeader, which if false, allows the autosizing to ignore the header cell and autosize only based on content cells.

• IgxTabs

  • The tabAlignment property of the IgxTabs component replaces the type property and enables you to set the tab alignment to start, center, end and justify.
  • The igx-tab-header supports igx-prefix and igx-suffix directives in its ng-content.

• IgxBottomNav

  • The IgxBottomNav component exposes disableAnimations property which determines whether the contents should animate when switching the selected item. The property is set to true by default which means that the animations are disabled.

• IgxOverlayService

  • detach and detachAll methods are added to IgxOverlayService. Calling detach will remove all the elements generated for the related overlay, as well as clean up all related resources. Calling detachAll will remove all elements generated by any call to IgxOverlay attach, and will clean up all related resources. Note: calling hide or hideAll will not clean generated by the service elements and will not clean up related resources.

• IgxCombo

  • Any changes to IComboItemAdditionEvent.addedItem will be reflected in the item added to the data.
  • IgxComboComponent.onAddition is now cancelable. You can prevent the item from being added by setting the event args cancel property to true.

  publichandleComboItemAddition(event: IComboItemAdditionEvent): void{if(event.addedItem[this.combo.valueKey]==='ForbiddenValue'){event.cancel=true;}elseif(event.addedItem[this.combo.valueKey]==='Change Me'){constindex=this.iter++;event.addedItem={[this.combo.valueKey]: `customId${index}`,[this.combo.displayKey]: `New item ${index}`;}}}

Themes:

• Breaking Changes:

  • IgxButton theme has been simplified. The number of theme params (igx-button-theme) has been reduced significantly and no longer includes prefixed parameters (flat-*, raised-*, etc.). See the migration guide to update existing button themes. Updates performed with ng update will migrate existing button themes but some additional tweaking may be required to account for the abscense of prefixed params.
  • The igx-typography mixin is no longer implicitly included with igx-core. To use our typography styles users have to include the mixin explicitly:

  @include igx-core();
  /// Example with Indigo Design theme:
  @include igx-typography($font-family: $indigo-typeface, $type-scale: $indigo-type-scale);
