Row in JavaScript Grid control

23 Mar 2023 / 5 minutes to read

The row represents record details fetched from data source.

Row customization

Using event

You can customize the appearance of a row by using the rowDataBound event. The rowDataBound event triggers for every row. In the event handler, you can get the RowDataBoundEventArgs that contains details of the row.

import { Grid, RowDataBoundEventArgs } from '@syncfusion/ej2-grids';
import { data } from './datasource.ts';

let grid: Grid = new Grid({
    dataSource: data,
    enableHover: false,
    allowSelection: false,
    columns: [
        { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 100 },
        { field: 'CustomerID', headerText: 'Customer ID', width: 120 },
        { field: 'ShipCity', headerText: 'Ship City', width: 100 },
        { field: 'Freight', headerText: 'Freight', width: 100, format: 'C2' },
        { field: 'ShipName', headerText: 'Ship Name', width: 100 }
    ],
    rowDataBound: rowBound,
    height: 280
});
grid.appendTo('#Grid');

function rowBound(args: RowDataBoundEventArgs) {
    if (args.data['Freight'] < 30) {
        args.row.classList.add('below-30');
    } else if (args.data['Freight'] < 80) {
        args.row.classList.add('below-80');
    } else {
        args.row.classList.add('above-80');

    dataSource: data.slice(0, 8),
    columns: [
        { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 120, type: 'number' },
        { field: 'CustomerID', width: 140, headerText: 'Customer ID', type: 'string' },

Adding a new row programmatically

The Grid can add a new row between the existing rows using the addRecord method of the Grid.

This is demonstrated in the following sample:

Copied to clipboard
import { Grid, Edit } from '@syncfusion/ej2-grids';
import { data } from './datasource.ts';

Grid.Inject(Edit);

let grid: Grid = new Grid({
    dataSource: data,
    editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true },
    columns: [
        { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 100 },
        { field: 'CustomerID', headerText: 'Customer ID', width: 120 },
        { field: 'ShipCity', headerText: 'Ship City', width: 100 },
        { field: 'Freight', headerText: 'Freight', width: 100, format: 'C2' },
        { field: 'ShipName', headerText: 'Ship Name', width: 100 }
    ]
});

grid.appendTo('#Grid');

document.getElementById('addrow').onclick = () => {
  grid.addRecord(
  { OrderID: 3232, CustomerID: 'ALKIT', ShipCity: 'London', Freight: 40, ShipName: 'Que Delícia'}, 2);
};

When working with remote data, it is impossible to add a new row between the existing rows.

How to get the row information when hovering over the cell

It is possible to get the row information when hovering over the specific cell. This can be achieved by using the rowDataBound event and getRowInfo method of the Grid.

In the following sample, the mouseover event is bound to a grid row in the rowDataBound event, and when hovering over the specific cell, using the getRowInfo method, row information will be retrieved and displayed in the console.

Copied to clipboard
import { Grid, Edit } from '@syncfusion/ej2-grids';
import { data } from './datasource.ts';
import { MouseEventArgs } from '@syncfusion/ej2-base';

Grid.Inject(Edit);

let grid: Grid = new Grid({
    dataSource: data,
    rowDataBound: rowDataBound,
    editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true },
    columns: [
        { field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 100 },
        { field: 'CustomerID', headerText: 'Customer ID', width: 120 },
        { field: 'ShipCity', headerText: 'Ship City', width: 100 },
        { field: 'Freight', headerText: 'Freight', width: 100, format: 'C2' },
        { field: 'ShipName', headerText: 'Ship Name', width: 100 }
    ]
});

grid.appendTo('#Grid');

function rowDataBound(args) {
    args.row.addEventListener('mouseover', function(e) {
        console.log(grid.getRowInfo(e.target))
    })
}
