Angular 계층형 그리드 일괄 편집 및 거래

    The Batch Editing feature of the IgxHierarchicalGrid is based on the TransactionService. Follow the Transaction Service class hierarchy topic to see an overview of the igxTransactionService and details how it is implemented.

    In order to use the HierarchicalTransactionService with IgxHierarchicalGrid, but have it accumulating separate transaction logs for each island, a service factory should be provided instead. One is exported and ready for use as IgxHierarchicalTransactionServiceFactory.

    다음은 계층형 그리드 구성 요소에 대해 일괄 편집을 활성화하는 방법에 대한 자세한 예입니다.

    Angular Hierarchical Grid Batch Editing and Transactions Example

    The following sample demonstrates a scenario, where the hierarchicalGrid has batchEditing enabled and has row editing enabled. The latter will ensure that transaction will be added after the entire row edit is confirmed.

    Note

    트랜잭션 상태는 업데이트, 추가, 삭제된 모든 행과 마지막 상태로 구성됩니다.

    Usage

    시작하려면IgxHierarchicalGridModule 안에 app.module.ts 파일:

    // app.module.ts

...
import { IgxHierarchicalGridModule } from 'igniteui-angular';

@NgModule({
    ...
    imports: [..., IgxHierarchicalGridModule],
    ...
})
export class AppModule {}

    Then, all you need to do is enable batchEditing from your Hierarchical Grid:

    <igx-hierarchical-grid [data]="data" [batchEditing]="true">
  ...
</igx-hierarchical-grid>

    This will ensure a proper instance of Transaction service is provided for the igx-hierarchical-grid. The proper TransactionService is provided through a TransactionFactory. You can learn more about this internal implementation in the transactions topic.

    배치 편집이 활성화된 후, 바인딩된 데이터 소스를 정의IgxHierarchicalGrid 하고rowEditable true로 설정하여 다음과 같이 묶으세요:

    <igx-hierarchical-grid #hierarchicalGrid [batchEditing]="true" [data]="data" [primaryKey]="'Artist'"
    [height]="'580px'" [width]="'100%'" [rowEditable]="true" >
    ...
    <igx-row-island #childGrid [key]="'Albums'" [primaryKey]="'Album'" [rowEditable]="true">
        <igx-grid-toolbar></igx-grid-toolbar>
        ...
        <ng-template igxToolbarCustomContent let-grid="grid">
            <button igxButton [disabled]="!grid.transactions.canUndo" (click)="undo(grid)">Undo</button>
            <button igxButton [disabled]="!grid.transactions.canRedo" (click)="redo(grid)">Redo</button>
        </ng-template>
    </igx-row-island>
</igx-hierarchical-grid>
...
<div class="buttons-row">
    <div class="buttons-wrapper">
        <button igxButton [disabled]="!undoEnabledParent" (click)="undo(hierarchicalGrid)">Undo Parent</button>
        <button igxButton [disabled]="!redoEnabledParent" (click)="redo(hierarchicalGrid)">Redo Parent</button>
    </div>
</div>
...

    다음 코드는 API의transactions 사용법을 보여줍니다 - 실행 취소, 재실행, 커밋.

    ...
export class HierarchicalGridBatchEditingSampleComponent {
    public undo(grid: any) {
        /* exit edit mode and commit changes */
        grid.endEdit(true);
        grid.transactions.undo();
    }

    public redo(grid: any) {
        /* exit edit mode and commit changes */
        grid.endEdit(true);
        grid.transactions.redo();
    }

    public commit() {
        this.hierarchicalGrid.transactions.commit(this.data);
        this.childGrid.hgridAPI.getChildGrids().forEach((grid) => {
            grid.transactions.commit(grid.data);
        });
        this.dialogChanges.close();
    }
}
    Note

    트랜잭션 API는 편집 종료를 처리하지 않으므로 직접 해야 합니다. 그렇지 않으면Hierarchical Grid 편집 모드로 유지할 것입니다. 그 방법 중 하나는 해당 메서드를 호출endEdit 하는 것입니다.

    Note

    속성을 비활성화하면rowEditable 셀 변경 시 트랜잭션이 생성되도록 변경Hierarchical Grid 되며, UI에서 행 편집 오버레이가 노출되지 않습니다.
