# DevExtreme
DevExtreme (by DevExpress) supports OData as a data source (opens new window). However, it supports only OData 4.0, not OData 4.01. To support Lodata you must send the "OData-Version" header with every request.
Alternatively, you can configure Lodata to default to OData 4.0 if the client does not specify a version by modifying the configuration.
This Vue example shows how to send the header, and load data into a DxDataGrid.
<template>
<DxDataGrid
:data-source="dataSource"
:show-borders="true"
>
<DxColumn data-field="id"/>
<DxColumn data-field="name"/>
<DxColumn data-field="email"/>
</DxDataGrid>
</template>
<script>
import 'devextreme/data/odata/store';
import { DxDataGrid, DxColumn } from 'devextreme-vue/data-grid';
export default {
components: {
DxDataGrid,
DxColumn,
},
data() {
return {
dataSource: {
store: {
type: 'odata',
url: 'http://localhost:8000/odata/Users',
beforeSend: function (e) {
e.headers = {
'OData-Version': '4.0'
};
},
key: 'id',
version: 4
},
select: [
'id',
'name',
'email'
]
},
};
},
};
</script>
