11.2.0-alpha.5

General

• IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
  • Breaking Change - The locale and pipeArgs parameters are removed from the operate method exposed by the IgxNumberSummaryOperand, IgxDateSummaryOperand, IgxCurrencySummaryOperand and IgxPercentSummaryOperand. They are now set in the igx-grid-summary-cell template. To change the locale and format setting of the igx-grid-summary-cell the user can use the new summaryFormatter property of the IgxColumnComponent.
• IgxTabs, IgxBottomNav
  • Breaking Change - IgxTabs and IgxBottomNav components were completely refactored in order to provide more flexible and descriptive way to define tab headers and contents. Please make sure to update via ng update in order to migrate the existing igx-tabs and igx-bottom-nav definitions to the new ones.
• IgxForOfDirective
  • Breaking Change - IgxForOfDirective events are renamed as follows:
    • onChunkLoad -> chunkLoad
    • onScrollbarVisibilityChanged -> scrollbarVisibilityChanged
    • onContentSizeChange -> contentSizeChange
    • onDataChanged -> dataChanged
    • onBeforeViewDestroyed -> beforeViewDestroyed
    • onChunkPreload -> chunkPreload
    • onDataChanging -> dataChanging
• IgxColumnComponent
  • Breaking Change - The onColumnChange output is renamed to columnChange.
• Breaking Change - IgxHierarchicalGrid and igxRowIsland events are renamed as follows:
  • onGridCreated -> gridCreated
  • onGridInitialized -> gridInitialized
  • onDataPreLoad -> dataPreLoad

New Features

• 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-template igxRowAddText>
                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.
  • 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.

  public handleComboItemAddition(event: IComboItemAdditionEvent): void {
      if (event.addedItem[this.combo.valueKey] === 'ForbiddenValue') {
          event.cancel = true;
      } else if (event.addedItem[this.combo.valueKey] === 'Change Me') {
          const index = 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);
