Angular 그리드 페이징

Pagination is used to split a large set of data into a sequence of pages that have similar content. Angular table pagination improves user experience and data interaction. Grid pagination is configurable via a separate component projected in the grid tree by defining a igx-paginator tag, similar to adding of a column. As in any Angular Table, the pagination in the Grid supports template for custom pages.

Angular Pagination Example

The following example represents Grid pagination and exposes the options usage of items per page and how paging can be enabled. The user can also quickly navigate through the Grid pages via "Go to last page" and "Go to first page" buttons.

Adding a igx-paginator component will control whether the feature is present, you can enable/disable it by using a simple *ngIf with a toggle property. The perPage input controls the visible records per page. Let’s update our Grid to enable paging:

<igx-grid #grid [data]="data" [height]="'500px'" [width]="'100%'">
    <igx-paginator [perPage]="10">
    </igx-paginator>
</igx-grid>

<igx-paginator #paginator [totalRecords]="20">
    <igx-paginator-content>
        <div id="numberPager" style="justify-content: center;">
            <button [disabled]="paginator.isFirstPage" (click)="paginator.previousPage()" igxButton="flat">
                PREV
            </button>
            <span>
               Page {{paginator.page}} of {{paginator.totalPages}}
            </span>
            <button [disabled]="paginator.isLastPage" (click)="paginator.nextPage()" igxButton="flat">
                NEXT
            </button>
        </div>
    </igx-paginator-content>
</igx-paginator>

Paging with Group By

그룹 행은 데이터 행과 함께 페이징 프로세스에 참여합니다. 각 페이지의 페이지 크기에 포함됩니다. 축소된 행은 페이징 프로세스에 포함되지 않습니다. 페이징과 그룹화 기준 간의 통합은 그룹화 기준 항목에 설명되어 있습니다.

Usage

The igx-paginator component is used along with the igx-grid component in the example below, but you can use it with any other component in case paging functionality is needed.

<igx-grid #grid [data]="data">
    <igx-paginator #paginator [(page)]="grid.page" [totalRecords]="grid.totalRecords" [(perPage)]="10"
            [selectOptions]="selectOptions">
    </igx-paginator>
</igx-grid>

Paginator Component Demo

Remote Paging

Remote paging can be achieved by declaring a service, responsible for data fetching and a component, which will be responsible for the Grid construction and data subscription. For more detailed information, check the Grid Remote Data Operations topic.

Remote Paging with Custom Template

In some cases you may want to define your own paging behavior and this is when we can take advantage of the igx-paginator-content and add our custom logic along with it. This section explains how we are going to extend the Remote Paging example in order to demonstrate this.

스타일링

To get started with styling the paginator, we need to import the index file, where all the theme functions and component mixins live:

@use "igniteui-angular/theming" as *;

// IMPORTANT: Prior to Ignite UI for Angular version 13 use:
// @import '~igniteui-angular/lib/core/styles/themes/index';

가장 간단한 방법을 따라, 우리는 를paginator-theme 확장하고 와$text-color$background-color 매개변수를 수용하는 새로운 테마를 만듭니다.$border-color

$dark-paginator: paginator-theme(
  $text-color: #d0ab23;,
  $background-color: #231c2c,
  $border-color: #d0ab23;
);

As seen, the paginator-theme only controls colors for the paging container, but does not affect the buttons in the pager UI. To style those buttons, let's create a new icon button theme:

$dark-button: icon-button-theme(
  $foreground: #d0ab23,
  $hover-foreground: #231c2c,
  $hover-background: #d0ab23,
  $focus-foreground: #231c2c,
  $focus-background: #d0ab23,
  $disabled-foreground: #9b7829
);

Note

우리가 방금 한 것처럼 색상 값을 하드코딩하는 대신, andpalette 함수를 사용color 해 색상 측면에서 더 큰 유연성을 얻을 수 있습니다. 사용 방법에 대한 자세한 안내는 해당 주제를 참고Palettes 해 주세요.

마지막 단계는 각각 해당 테마가 있는 구성 요소 믹스인을 포함하는 것입니다.

@include css-vars($dark-paginator);

.igx-grid-paginator__pager {
  @include css-vars($dark-button);
}

Note

We include the created icon-button-theme within .igx-paginator__pager, so that only the paginator buttons would be styled. Otherwise other icon buttons in the grid would be affected too.

Note

If the component is using an Emulated ViewEncapsulation, it is necessary to penetrate this encapsulation using ::ng-deep in order to style the components which are inside the paging container, like the button:

@include css-vars($dark-paginator);

:host {
  igx-paginator {
    ::ng-deep {
      @include css-vars($dark-button);
    }
  }
}
