DataSourceRequestState

Premium

Updated on Jan 16, 2026

Represents the state required by the toDataSourceRequest and toDataSourceRequestString methods.

The DataSourceRequestState is an extension of the State type with an additional aggregates field—an array of AggregateDescriptor.

The aggregates field is required for serialization of aggregate descriptors in the request and does not replace the aggregate field of the GroupDescriptor used by the group field.

ts

import { DataSourceRequestState } from '@progress/kendo-data-query';

const state: DataSourceRequestState = {
    skip: 0,
    take: 10,
    sort: [{ field: 'ProductName', dir: 'asc' }],
    group: [
        {
            field: 'Category',
            aggregates: [{ field: 'UnitPrice', aggregate: 'sum' }] // GroupDescriptor aggregates
        }
    ],
    aggregates: [{ field: 'UnitPrice', aggregate: 'sum' }] // DataSourceRequestState aggregates
};
