You can change the column headerText
dynamically through an external button.
Follow the given steps to change the header text dynamically:
Step 1:
Get the column object corresponding to the field name by using the getColumnByField
method.
Then, change the header text value.
let column = grid.getColumnByField("ShipCity"); // Get column object.
column.headerText = 'Changed Text';
Step 2:
To reflect the changes in the grid header, invoke the refreshHeader
method.
grid.refreshHeader();
import { Grid, Column } from '@syncfusion/ej2-grids';
import { data } from './datasource.ts';
import { Button } from '@syncfusion/ej2-buttons';
let grid: Grid = new Grid({
dataSource: data,
columns: [
{ field: 'OrderID', headerText: 'Order ID', textAlign: 'Right', width: 100 },
{ field: 'CustomerID', headerText: 'Customer ID', width: 120 },
{ field: 'ShipCity', headerText: 'Ship City', width: 120 },
{ field: 'ShipName', headerText: 'Ship Name', width: 100 }
],
height: 280
});
grid.appendTo('#Grid');
let btn: Button = new Button({ cssClass: 'e-flat' }, '#change-text');
document.getElementById('change-text').addEventListener('click', () => { // changing the header text for ShipCity column.
let column: Column = grid.getColumnByField("ShipCity"); // get the JSON object of the column corresponding to the field name.
column.headerText = "Changed Text"; // assign a new header text to the column.
grid.refreshHeader();
});
