27 Jan 20237 minutes to read

You can customize the row height of treegrid rows through the rowHeight property. The rowHeight property is used to change the row height of entire treegrid rows.

In the below example, the rowHeight is set as 60px.

app.jsx

import { ColumnDirective, ColumnsDirective, TreeGridComponent } from '@syncfusion/ej2-react-treegrid';
import * as React from 'react';
import { sampleData } from './datasource';
export default class App extends React.Component {
    render() {
        return <TreeGridComponent dataSource={sampleData} treeColumnIndex={1} childMapping='subtasks' height='275' rowHeight='60'>
            <ColumnsDirective>
              <ColumnDirective field='taskID' headerText='Task ID' width='90' textAlign='Right'/>
              <ColumnDirective field='taskName' headerText='Task Name' width='180'/>
              <ColumnDirective field='startDate' headerText='Start Date' width='90' format='yMd' textAlign='Right' type='date'/>
              <ColumnDirective field='duration' headerText='Duration' width='80' textAlign='Right'/>
            </ColumnsDirective>
        </TreeGridComponent>;
    }
}

app.tsx

import { ColumnDirective, ColumnsDirective, TreeGridComponent } from '@syncfusion/ej2-react-treegrid';
import * as React from 'react';
import { sampleData } from './datasource';

export default class App extends React.Component<{}, {}>{
    public render() {
        return <TreeGridComponent dataSource={sampleData} treeColumnIndex={1} childMapping='subtasks'
         height='275' rowHeight='60'>
            <ColumnsDirective>
              <ColumnDirective field='taskID' headerText='Task ID' width='90' textAlign='Right'/>
              <ColumnDirective field='taskName' headerText='Task Name' width='180'/>
              <ColumnDirective field='startDate' headerText='Start Date' width='90' format='yMd' textAlign='Right' type='date' />
              <ColumnDirective field='duration' headerText='Duration' width='80' textAlign='Right' />
            </ColumnsDirective>
        </TreeGridComponent>
    }
}

Customize row height for particular row

TreeGrid row height for particular row can be customized using the rowDataBound event by setting the rowHeight in arguments for each row based on the requirement.

In the below example, the row height for the row with Task ID as 3 is set as 90px using the rowDataBound event.

app.jsx

import { getObject } from '@syncfusion/ej2-grids';
import { ColumnDirective, ColumnsDirective, TreeGridComponent } from '@syncfusion/ej2-react-treegrid';
import * as React from 'react';
import { sampleData } from './datasource';
export default class App extends React.Component {
    rowDataBound(args) {
        if (getObject('taskID', args.data) === 3) {
            args.rowHeight = 90;
        }
    }
    render() {
        this.rowDataBound = this.rowDataBound.bind(this);
        return <TreeGridComponent dataSource={sampleData} treeColumnIndex={1} childMapping='subtasks' height='275' rowDataBound={this.rowDataBound}>
            <ColumnsDirective>
              <ColumnDirective field='taskID' headerText='Task ID' width='90' textAlign='Right'/>
              <ColumnDirective field='taskName' headerText='Task Name' width='180'/>
              <ColumnDirective field='startDate' headerText='Start Date' width='90' format='yMd' textAlign='Right' type='date'/>
              <ColumnDirective field='duration' headerText='Duration' width='80' textAlign='Right'/>
            </ColumnsDirective>
        </TreeGridComponent>;
    }
}

app.tsx

import { getObject, RowDataBoundEventArgs } from '@syncfusion/ej2-grids';
import { ColumnDirective, ColumnsDirective, TreeGridComponent } from '@syncfusion/ej2-react-treegrid';
import * as React from 'react';
import { sampleData } from './datasource';

export default class App extends React.Component<{}, {}>{
    public rowDataBound(args: RowDataBoundEventArgs) {
        if(getObject('taskID', args.data) === 3){
            args.rowHeight = 90;
        }
    }

    public render() {
        this.rowDataBound = this.rowDataBound.bind(this);
        return <TreeGridComponent dataSource={sampleData} treeColumnIndex={1} childMapping='subtasks'
         height='275' rowDataBound={this.rowDataBound}>
            <ColumnsDirective>
              <ColumnDirective field='taskID' headerText='Task ID' width='90' textAlign='Right'/>
              <ColumnDirective field='taskName' headerText='Task Name' width='180'/>
              <ColumnDirective field='startDate' headerText='Start Date' width='90' format='yMd' textAlign='Right' type='date' />
              <ColumnDirective field='duration' headerText='Duration' width='80' textAlign='Right' />
            </ColumnsDirective>
        </TreeGridComponent>
    }
}
