To customize the default values of pager drop-down, you need to define the pageSizes
as array of strings.
import { Grid, Page } from '@syncfusion/ej2-grids';
import { data } from './datasource.ts';
Grid.Inject(Page);
let grid: Grid = new Grid({
dataSource: data,
allowPaging: true,
pageSettings:{pageSizes: ["5", "10", "All"]},
columns: [
{ field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 120 },
{ field: 'CustomerID', headerText: 'Customer ID', width: 150 },
{ field: 'ShipCity', headerText: 'Ship City', width: 150 },
{ field: 'ShipName', headerText: 'Ship Name', width: 150 }
],
});
grid.appendTo('#Grid');
