MongoDB Service

Use the third-party devextreme-query-mongodb extension to query data from MongoDB. This extension implements data processing on a server according to the protocol the Lookup uses. To access the server from the client, configure the CustomStore as described in the Custom Sources article or use the createStore method. This method is a part of the DevExtreme.AspNet.Data extension. The following code shows how to use this method.

jQuery
JavaScript
$(function() {
    const serviceUrl = "http://url/to/my/service";
    $("#lookupContainer").dxLookup({
        dataSource: DevExpress.data.AspNet.createStore({
            key: "ID",
            loadUrl: serviceUrl
        }),
        // ...
    })
});
Angular
HTML
TypeScript
<dx-lookup ...
    [dataSource]="store">
</dx-lookup>
import { DxLookupModule } from "devextreme-angular";
import CustomStore from "devextreme/data/custom_store";
import { createStore } from "devextreme-aspnet-data-nojquery";
// ...
export class AppComponent {
    store: CustomStore;
    constructor() {
        const serviceUrl = "http://url/to/my/service";
        this.store = createStore({
            key: "ID",
            loadUrl: serviceUrl
        })
    }
}
@NgModule({
    imports: [
        // ...
        DxLookupModule
    ],
    // ...
})
Vue
<template>
    <DxLookup ...
        :data-source="store"
    />
</template>

<script>
import 'devextreme/dist/css/dx.common.css';

import { DxLookup } from 'devextreme-vue/lookup';
import { createStore } from "devextreme-aspnet-data-nojquery";

const serviceUrl = "http://url/to/my/service";

export default {
    components: {
        DxLookup
    },
    data() {
        return {
            store: createStore({
                key: "ID",
                loadUrl: serviceUrl
            })
        };
    }
}
</script>
React
import React from 'react';
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import { Lookup } from 'devextreme-react/lookup';
import { createStore } from "devextreme-aspnet-data-nojquery";

const serviceUrl = "http://url/to/my/service";

class App extends React.Component {
    constructor(props) {
        super(props);

        this.store = createStore({
            key: "ID",
            loadUrl: serviceUrl
        });
    }

    render() {
        return (
            <Lookup ...
                dataSource={this.store}
            />
        );
    }
}

export default App;
