Auto fit columns in EJ2 TypeScript Treegrid control

27 Apr 20234 minutes to read

The autoFitColumns method resizes the column to fit the widest cell’s content without wrapping. You can autofit a specific column at initial rendering by invoking the autoFitColumns method in dataBound event.

index.ts
index.html
import { TreeGrid, Resize } from '@syncfusion/ej2-treegrid';
import { sampleData } from './datasource.ts';

TreeGrid.Inject(Resize);

let treeGridObj: TreeGrid = new TreeGrid({
    dataSource: sampleData,
    childMapping: 'subtasks',
    allowResizing: true,
    dataBound: () => treeGridObj.autoFitColumns(['taskName']),
    height: 315,
    treeColumnIndex: 1,
    columns: [
        { field: 'taskID', headerText: 'Task ID', textAlign: 'Right', width: 90 },
        { field: 'taskName', headerText: 'Task Name', width: 60 },
        {
            field: 'startDate', headerText: 'Start Date', format: 'yMd', width: 120, textAlign:'Right'
        },
        { field: 'duration', headerText: 'Duration', width: 120, textAlign: 'Right' },
        { field: 'progress', headerText: 'Progress', width: 120, textAlign: 'Right' }
    ]
});

treeGridObj.appendTo('#TreeGrid');
