Exporting filtered data in Angular Treegrid component

21 Sep 20225 minutes to read

You can export the filtered data by defining the resulted data in PdfExportProperties.dataSource before export.

In the below Pdf exporting demo, We have gotten the filtered data from the filteredResult of Tree Grid filterModule and then defines the resulted data in PdfExportProperties.dataSource and pass it to pdfExport method.

import { Component, OnInit, ViewChild } from '@angular/core';
import { projectData } from './datasource';
import { TreeGridComponent, ToolbarItems, ToolbarService, PdfExportService,
 PageService, FilterService } 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, FilterService],
    template: `<ejs-treegrid #treegridObj [dataSource]='data' idMapping='TaskID' parentIdMapping='parentID' [treeColumnIndex]='1' [allowFiltering]='true' [allowPaging]='true' [pageSettings]='initialPage' [allowPdfExport]='true' [toolbar]='toolbarOptions' (toolbarClick)='toolbarClick($event)' >
            <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='Start 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 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.toolbarOptions = ['PdfExport'];
        this.initialPage = { pageCount: 5, pageSize: 5 };
    toolbarClick(args: ClickEventArgs) {
    if (this.treegridObj && args.item.text === 'PDF Export') {
      let pdfdata;
      pdfdata = this.treegridObj.filterModule.filteredResult;
      const exportProperties = {
        dataSource: pdfdata,
     if (this.treegridObj) {
import { NgModule,ViewChild } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { TreeGridModule } from '@syncfusion/ej2-angular-treegrid';
import { PageService, SortService, FilterService } from '@syncfusion/ej2-angular-treegrid';
import { AppComponent } from './app.component';
import {ButtonModule} from '@syncfusion/ej2-angular-buttons';
import { DropDownListAllModule } from '@syncfusion/ej2-angular-dropdowns';
