6.2.0 RC 2

6.2.0 RC 2

• Display density can be specified by using the injection token DisplayDensityToken and providing a value (comfortable, cosy or compact) on an application or a component level.

  Setting display density on a component level:

  @Component({
  ...
  providers: [{ provide: DisplayDensityToken, useValue: { displayDensity: DisplayDensity.compact} }]
  })

• igx-input-group

  • The igx-input-group control's display density can be explicitly set by using the displayDensity input.

  <igx-input-group [displayDensity]="'cosy'"> ... </igx-input-group>

• igx-drop-down:

  • Added a new boolean argument cancel to the onSelection ISelectionEventArgs. Its default value is false, in case it is set to true, the drop down selection is invalidated.

• igxIcon:

  • Breaking change glyphName property is removed from IgxIconComponent. For Material icons the icon name should be explicitly defined between the opening and closing tags. Font Awesome icons should use the name property now.
  • Added support for custom SVG icons. Register the SVG icons with the IgxIconService and use IgxIconComponent's name and fontSet properties to visualize the icon.

• Transaction Provider - TransactionService is an injectable middleware that a component can use to accumulate changes without affecting the underlying data. The provider exposes API to access, manipulate changes (undo and redo) and discard or commit all to the data.
  For more detailed information, see the README.

• igxTreeGrid:

  • New IgxTreeGridComponent added.
  • The igxTreeGrid is used to display and manipulate hierarchical data with consistent schema, formatted as a table and provides a line of advanced features such as sorting, filtering, editing, column pinning, column moving, column hiding, paging and others.
  • The igxTreeGrid provides two ways of defining the relations among our data objects - by using a child collection for every data object or by using primary and foreign keys for every data object.
  • For more details on using the igxTreeGrid, take a look at the official documentation.

• igxGrid:

  • Breaking change onGroupingDone - The array of ISortingExpression can now be accessed through the expressions event property. Two new properties have been added to the event arguments - groupedColumns and ungroupedColumns. They provide references to arrays of IgxColumnComponent that hold the columns which have changed their state because of the last grouping/ungrouping operation.

  • Breaking change onEditDone event is renamed to onCellEdit and new cell editing events are introduced: onCellEditEnter and onCellEditCancel. When row editing is enabled, the corresponding events are emitted by the grid - onRowEditEnter, onRowEdit, onRowEditCancel. All these events have arguments that are using the IGridEditEventArgs interface.

  • Row editing - allows modification of several cells in the row, before submitting, at once, all those changes to the grid's data source. Leverages the pending changes functionality of the new transaction provider.

    <igx-grid [data]="data" [rowEditable]="true">
        <igx-column field="ProductName"></igx-column>
        <igx-column field="ReleaseDate"></igx-column>
    </igx-grid>

  • Batch editing - an injectable transaction provider accumulates pending changes, which are not directly applied to the grid's data source. Those can later be inspected, manipulated and submitted at once. Changes are collected for individual cells or rows, depending on editing mode, and accumulated per data row/record.

    @Component({
        providers: [{ provide: IgxGridTransaction, useClass: IgxTransactionService }],
        selector: "app-grid-with-transactions",
        template: "<ng-content></ng-content>"
    })
    export class GridWithTransactionsComponent { }

  • A new boolean hideGroupedColumns input controls whether the grouped columns should be hidden as well (defaults to false).

  • Breaking change cellClasses input on IgxColumnComponent now accepts an object literal to allow conditional cell styling.

  • Exposing a mechanism for cells to grow according to their content.

  • sortStrategy input exposed to provide custom sort strategy for the IgxColumnComponent. The custom strategy should implement the ISortingStrategy interface, or can extend the base SortingStrategy class and override all or some of its public/protected members.

  • New quick filtering functionality is implemented. Filtering icon is removed from column header and a filtering row is introduced in the grid's header.

• igxFor

  • Added support for variable heights.

• igx-datePicker selector is deprecated. Use igx-date-picker selector instead.

• igxOverlay:

  • OverlaySettings now also accepts an optional outlet to specify the container where the overlay should be attached.
  • when show and hide methods are called onAnimation event fires. In the arguments of this event there is a reference to the animationPlayer, animationType (either open or close) and to the overlay id.
  • if you call show/hide methods of overlay, while opening/closing animation is still ongoing, the animation will stop and respective open/close animation will start.

• igxToggleAction new outlet input controls the target overlay element should be attached. Provides a shortcut for overlaySettings.outlet.

• IgxOverlayOutlet directive introduced to mark an element as an igxOverlay outlet container. ReadMe

• igxButtonGroup

  • Added the ability to define buttons directly in the template

• igx-time-picker:

  • Introduced specialDates. This property is exposed from the igx-calendar component.
  • Introduced deselectDate method added that deselects the calendar date.

• IgxTextHighlightDirective: The highlight method now has a new optional parameter called exactMatch (defaults to false).

  • If its value is false, all occurrences of the search text will be highlighted in the group's value.
  • If its value is true, the entire group's value should equals the search text in order to be highlighted (caseSensitive argument is respected as well).

• IgxGrid: The findNext and findPrev methods now have a new optional parameter called exactMatch (defaults to false).

  • If its value is false, all occurrences of the search text will be highlighted in the grid's cells.
  • If its value is true, the entire value of each cell should equals the search text in order to be highlighted (caseSensitive argument is respected as well).

• IgxChip

  • Introduced event argument types to all EventEmitter @Outputs.
  • Breaking change onSelection's EventEmitter interface property nextStatus is renamed to selected.
  • Breaking change Move the location of where the chip suffix is positioned. Now it is between the content and the remove button making the button last element if visible by default.
