27 Sep 20235 minutes to read

SortDirection allows you to sort the columns bounded to the Query Builder to view the columns by ascending or descending order. You should set the sortDirection property to sort the fields.

app.component.ts

import { Component, OnInit } from '@angular/core';
import { RuleModel } from '@syncfusion/ej2-angular-querybuilder';
import { hardwareData } from './datasource';

@Component({
    selector: 'app-root',
    template: `<!-- To render Query Builder. -->
               <ejs-querybuilder #querybuilder width="70%" [dataSource]="data" [rule]="importRules"  sortDirection="Descending">
                <e-columns>
                  <e-column field="TaskID" label="Task ID" type="number"></e-column>
                  <e-column field="Name" label="Name" type="string"></e-column>
                  <e-column field="Category" label="Category" type="string"></e-column>
                  <e-column field="SerialNo" label="SerialNo" type="string"></e-column>
                  <e-column field="InvoiceNo" label="InvoiceNo" type="string"></e-column>
                  <e-column field="Status" label="Status" type="string"></e-column>
                </e-columns>
              </ejs-querybuilder>`
})

export class AppComponent implements OnInit {
    public data?: Object[];
    public importRules?: RuleModel;
    ngOnInit(): void {
        this.data = hardwareData;
        this.importRules = {
        'condition': 'or',
        'rules': [{
            'label': 'Category',
            'field': 'Category',
            'type': 'string',
            'operator': 'equal',
            'value': 'Laptop'
        },
        {
        'condition': 'and',
            'rules': [{
                'label': 'Status',
                'field': 'Status',
                'type': 'string',
                'operator': 'notequal',
                'value': 'Pending'
            },
            {
                'label': 'Task ID',
                'field': 'TaskID',
                'type': 'number',
                'operator': 'equal',
                'value': 5675
            }]
        }]
    };
    }
}
