Pdf export in Angular Treegrid component

27 Sep 202319 minutes to read

PDF export allows exporting TreeGrid data to PDF document. You need to use the pdfExport method for exporting. To enable PDF export in the treegrid, set the allowPdfExport as true.

To use PDF export, inject the PdfExport module in treegrid.

You can check this video to learn about how to perform Exporting and its customization in Angular TreeGrid.

app.component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { sampleData } from './datasource';
import { ToolbarItems } from '@syncfusion/ej2-treegrid';
import { PdfExportProperties } from '@syncfusion/ej2-grids';
import { TreeGridComponent } from '@syncfusion/ej2-angular-treegrid';

@Component({
    selector: 'app-container',
    template: `<ejs-treegrid [dataSource]='data' #treegrid height='220' (toolbarClick)='toolbarClick($event)' [allowPaging]='true' [allowPdfExport]='true' [pageSettings]='pager' [treeColumnIndex]='1'  childMapping='subtasks' [toolbar]='toolbarOptions'>
        <e-columns>

})
export class AppComponent implements OnInit {

    public data?: Object[];
    public pager?: Object;
    @ViewChild('treegrid')
    public treeGridObj?: TreeGridComponent;
    public toolbarOptions?: ToolbarItems[];

    ngOnInit(): void {
        this.data = sampleData;
        this.pager = { pageSize: 7 };
        this.toolbarOptions = ['PdfExport'];
    }
    toolbarClick(args: Object | any) : void {
        if (args['item'].text === 'PDF Export') {
            (this.treeGridObj as TreeGridComponent).pdfExport();
        }
    }
}

Show spinner while exporting

Show or hide the spinner component while exporting the tree grid using the showSpinner or hideSpinner methods. Use the toolbarClick event to show spinner before exporting and hide a spinner in the pdfExportComplete event after the export.

In the following demo, the default spinner component is rendered when exporting the tree grid.

app.component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { sampleData } from './datasource';
import { TreeGridComponent, ToolbarItems } from '@syncfusion/ej2-angular-treegrid';
import { ClickEventArgs } from '@syncfusion/ej2-angular-navigations';

@Component({
    selector: 'app-container',
    template: `<ejs-treegrid #treegrid id='TreeGrid' [dataSource]='data' height='220' (toolbarClick)='toolbarClick($event)' [allowPaging]='true' [allowPdfExport]='true' [treeColumnIndex]='1'  childMapping='subtasks' [toolbar]='toolbarOptions' (pdfExportComplete)='pdfExportComplete()'>
                    <e-columns>
                        <e-column field='taskID' headerText='Task ID' textAlign='Right' width=90></e-column>
                        <e-column field='taskName' headerText='Task Name' textAlign='Left' width=180></e-column>
                        <e-column field='startDate' headerText='Start Date' textAlign='Right' format='yMd' width=120></e-column>
                        <e-column field='duration' headerText='Duration' textAlign='Right' width=110></e-column>
                    </e-columns>
                </ejs-treegrid>`
})
export class AppComponent implements OnInit {

    public data?: object[];
    public toolbarOptions?: ToolbarItems[];
    @ViewChild('treegrid')  public treegrid?: TreeGridComponent;

    ngOnInit(): void {
        this.data = sampleData;
        this.toolbarOptions = ['PdfExport'];
    }

    toolbarClick(args: ClickEventArgs): void {
        if (args['item'].text === 'PDF Export') {
            (this.treegrid as TreeGridComponent).showSpinner();
            (this.treegrid as TreeGridComponent).pdfExport();
        }
    }

    pdfExportComplete(): void {
        (this.treegrid as TreeGridComponent).hideSpinner();
    }
}

Custom data source

PDF export provides an option to define datasource dynamically before exporting. To export data dynamically, define the dataSource in exportProperties

app.component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { sampleData } from './datasource';
import { ToolbarItems } from '@syncfusion/ej2-treegrid';
import { PdfExportProperties, RowDataBoundEventArgs, PdfQueryCellInfoEventArgs } from '@syncfusion/ej2-grids';
import { TreeGridComponent } from '@syncfusion/ej2-angular-treegrid';

@Component({
    selector: 'app-container',
    template: `<ejs-treegrid [dataSource]='data' #treegrid height='220' (toolbarClick)='toolbarClick($event)' [allowPaging]='true' [allowPdfExport]='true' [pageSettings]='pager' [treeColumnIndex]='1'  childMapping='subtasks' [toolbar]='toolbarOptions'>
        <e-columns>
                    <e-column field='taskID' headerText='Task ID' textAlign='Right' width=90></e-column>
                    <e-column field='taskName' headerText='Task Name' textAlign='Left' width=180></e-column>
                    <e-column field='startDate' headerText='Start Date' textAlign='Right' format='yMd' width=120></e-column>
                    <e-column field='duration' headerText='Duration' textAlign='Right' width=110></e-column>
        </e-columns>
                </ejs-treegrid>`
})
export class AppComponent implements OnInit {

    public data?: Object[];
    public pager?: Object;
    @ViewChild('treegrid')
    public treeGridObj?: TreeGridComponent;
    public toolbarOptions?: ToolbarItems[];

    ngOnInit(): void {
        this.data = sampleData;
        this.pager = { pageSize: 7 };
        this.toolbarOptions = ['PdfExport'];
    }
    toolbarClick(args: Object| any) : void {
        if (args['item'].text === 'PDF Export') {
            let exportProperties: PdfExportProperties = {
                dataSource: sampleData,
            };
            (this.treeGridObj as TreeGridComponent).pdfExport(exportProperties);
        }
    }
}
