Select rows in grid based on certain condition in EJ2 TypeScript Grid control
13 Apr 20234 minutes to read
You can select the specific row in the grid based on a certain condition by using the selectRows
method in the dataBound
event of Grid.
In the below demo, we have selected the grid rows only when EmployeeID
column value greater than 3
.
import { Grid, Selection, Page } from '@syncfusion/ej2-grids';
import { data } from './datasource.ts';
Grid.Inject(Selection, Page);
let selIndex: any = [];
let grid: Grid = new Grid({
dataSource: data,
allowPaging: true,
selectionSettings: {type: "Multiple"},
columns: [
{ field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 120 },
{ field: 'CustomerID', headerText: 'Customer ID', width: 150 },
{ field: 'EmployeeID', headerText: 'Employee ID', textAlign: 'Right', width: 150 },
{ field: 'ShipCity', headerText: 'Ship City', width: 150 },
{ field: 'ShipName', headerText: 'Ship Name', width: 150 }
],
rowDataBound: function(args) {
if (args.data['EmployeeID'] > 3) {
selIndex.push(parseInt(args.row.getAttribute('aria-rowindex')));
}
},
dataBound: function(args) {
if (selIndex.length) {
this.selectRows(selIndex);
selIndex = [];
}
}
});
grid.appendTo('#Grid');
