Exporting selected data in Angular Treegrid component

21 Sep 20226 minutes to read

You can export the selected records data by passing it to PdfExportProperties.dataSource or ExcelExportProperties.dataSource property in the toolbarClick event.

In the below exporting demo, we can get the selected records using getSelectedRecords method and pass the selected data to pdfExport or excelExport methods using respective export properties..

import { Component, OnInit, ViewChild } from '@angular/core';
import { projectData } from './datasource';
import { TreeGridComponent, ToolbarItems, ToolbarService, PdfExportService, PageService, ExcelExportService, SelectionSettingsModel } from '@syncfusion/ej2-angular-treegrid';
import { ClickEventArgs } from '@syncfusion/ej2-angular-navigations';
import { PdfExportProperties } from '@syncfusion/ej2-angular-grids';

    selector: 'app-container',
    providers: [ToolbarService, PdfExportService, PageService, ExcelExportService],
    template: `<ejs-treegrid #treegridObj [dataSource]='data' idMapping='TaskID' parentIdMapping='parentID' [treeColumnIndex]='1' [allowPaging]='true' [pageSettings]='initialPage' [allowPdfExport]='true' [allowExcelExport]='true' [toolbar]='toolbarOptions' (toolbarClick)='toolbarClick($event)' [selectionSettings]='selectionSettings'>
            <e-column field='TaskID' headerText='Task ID' width='70' textAlign='Right'></e-column>
            <e-column field='TaskName' headerText='Task Name' width='100' ></e-column>
            <e-column field='StartDate' headerText='Start Date' textAlign='Right' [format]='formatOptions' editType='datepickeredit' [edit]='editOptions' width='100'></e-column>
            <e-column field='EndDate' headerText='End Date' textAlign='Right' [format]='formatOptions' editType='datepickeredit' [edit]='editOptions' width='100'></e-column>
            <e-column field='Duration' headerText='Duration' width='90' textAlign='Right'></e-column>
            <e-column field='Priority' headerText='Priority' width='90'></e-column>
export class AppComponent implements OnInit {

    public data: Object[] = [];
    public editOptions: Object;
    public formatOptions: Object;
    public toolbarOptions: ToolbarItems[];
    public selectionSettings: SelectionSettingsModel;
    public initialPage: object;
    public treegridObj: TreeGridComponent;

    ngOnInit(): void {
        this.data = projectData;
        this.editOptions = { params: { format: 'y/M/d' } };
        this.formatOptions = { format: 'y/M/d', type: 'date' };
        this.initialPage = { pageCount: 5, pageSize: 5 };
        this.toolbarOptions = ['PdfExport', 'ExcelExport'];
        this.selectionSettings = { type: 'Multiple'};
    toolbarClick(args: ClickEventArgs) {
      if (this.treegridObj && args.item.text === 'PDF Export') {
                const selectedRecords = this.treegridObj.getSelectedRecords();
                const exportProperties = {
                    dataSource: selectedRecords,
      else if (this.treegridObj && args.item.text === 'Excel Export') {
                const selectedRecords = this.treegridObj.getSelectedRecords();
                const exportProperties = {
                    dataSource: selectedRecords,
