Detail template in React TreeGrid

8 Oct 202510 minutes to read

The detail template displays additional information for a row. When a parent row is expanded, its child rows expand along with their detail templates. The detailTemplate property accepts either a template string or an HTML element ID.

To enable the detail template, inject the DetailRow module into the TreeGrid.

app.jsx

import { ColumnDirective, ColumnsDirective, TreeGridComponent, DetailRow, Inject } from '@syncfusion/ej2-react-treegrid';
import * as React from 'react';
import { textdata } from './datasource';
import { Internationalization } from '@syncfusion/ej2-base';
let instance = new Internationalization();
export default class App extends React.Component {
    format = (value) => {
        return instance.formatDate(value, { skeleton: 'yMd', type: 'date' });
    };
    detailtemplate(props) {
        var imag = './' + props.FullName + '.png';
        return (<div>
                <div style=>
                    <img src={imag}/>
                </div>
                <div style=>
                    <div className="e-description" style=>
                        <b>{props.Name}</b> was born on {this.format(props.DOB)}. Now lives at {props.Address}, {props.Country}. {props.Name} holds a position of <b>{props.Designation}</b> in our WA department, (Seattle USA).</div>
                    <div className="e-description" style=>
                        <b style=>Contact:</b>{props.Contact}
