var ds = new kendo.data.DataSource({
    data: [
      {"foo": {"bar": 10}},
      {"foo": {"bar": 10}},
      {"foo": {"bar": 10}},
      {"foo": {"bar": 20}}
    ],

    aggregate: [
      {field: "foo.bar", aggregate: "sum"}
    ]
})
ds.read();
console.log('results', ds.view().length);
console.log('aggregates', ds.aggregates());
console.log('run filter')
ds.query({filter:{field: "foo.bar", operator: "eq", value: 20}})
console.log('results', ds.view().length);
console.log('aggregates', ds.aggregates());

Hello Sam,

The dataSource's query() method resets the aggregate configuration by default. Therefore, to maintain it in the query result you can pass it as follows:

<script>
  ds.query({filter:{field: "foo", operator: "eq", value: 20}, aggregate: ds.aggregate()}).then(function() {
    console.log('results', ds.view().length);
    console.log('aggregates', ds.aggregates());
  })
</script>

Regards,
Dimitar
