Dictionaries contain localized strings for different languages. The strings are key/value pairs and are shipped as JavaScript or JSON files (depending on the package you use).

All dictionaries are contributed and curated by the community. The list of dictionaries is available on GitHub.

jQuery

You can find all the dictionaries on your local machine in the DevExtreme installation folder's or ZIP archive's Lib\js\localization directory. These dictionaries are also available on CDN.

Use the <script> tag to link the required dictionaries, and place the links after a link to the DevExtreme library:

HTML

    </script>
</body>

Angular

You can find all the dictionaries on your local machine in the DevExtreme installation folder's or ZIP archive's Lib\js\localization directory. These dictionaries are also available on npm.

Include the dictionaries using the import or require statement the statement depends on the syntax for working with modules. The following code shows ECMAScript 6 and CommonJS syntaxes:

Create a New Dictionary

To make a dictionary for a new locale:

Copy one of the available dictionaries.
Rename it according to the new locale.
Translate the strings in it and change the locale key.

You can submit JSON dictionaries to our repository on GitHub. You should refer to our Contribution Guide before submitting content.

Add Strings to a Dictionary

In the following example, the loadMessages(messages) method adds a string with the greetingMessage key to the English and German dictionaries. The formatMessage(key, value) method then uses this key to retrieve the string from the dictionary that corresponds to the locale set by the locale(locale) method.

jQuery

JavaScript

HTML

$(function() {
    var userName = "John";
    DevExpress.localization.loadMessages({
        "en": {
            "greetingMessage": "Good morning, {0}!"
        },
        "de": {
            "greetingMessage": "Guten morgen, {0}!"
        }
    });
    DevExpress.localization.locale(navigator.language);
    $("#greeting").text(
        DevExpress.localization.formatMessage("greetingMessage", userName)

Override Strings in a Dictionary

To override a string, find its key in any dictionary and use it to specify the new string value.

In the following code, we override two strings from the English dictionary:

jQuery

JavaScript

$(function() {
    DevExpress.localization.loadMessages({
        "en": {
            "dxDataGrid-editingDeleteRow": "Remove",
            "dxDataGrid-editingUndeleteRow": "Recover"
        }
    });
});

Angular

app.component.ts

import { Component } from '@angular/core';
import { loadMessages } from 'devextreme/localization';

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent {
    constructor() {
        loadMessages({
            "en": {
                "dxDataGrid-editingDeleteRow": "Remove",
                "dxDataGrid-editingUndeleteRow": "Recover"
            }
        });
    }
}

Vue

App.vue

<template>
    <!-- ... -->

<script>
import { loadMessages } from 'devextreme/localization';

export default {
    created() {
        loadMessages({
            "en": {
                "dxDataGrid-editingDeleteRow": "Remove",
                "dxDataGrid-editingUndeleteRow": "Recover"
            }
        });
    }
}
</script>

React

App.js

import React from 'react';

import { loadMessages } from 'devextreme/localization';

class App extends React.Component {
    constructor(props) {
        super(props);
        loadMessages({
            "en": {
                "dxDataGrid-editingDeleteRow": "Remove",
                "dxDataGrid-editingUndeleteRow": "Recover"
            }
        });
    }

    render() {
        return (
            { /* ... */}
        );
    }
}
export default App;

Localize Dates, Numbers, and Currencies

DevExtreme enables you to localize date, number and currency values using Intl or Globalize. We recommend using Intl because it is supported out of the box. You can use Globalize instead if the target browser do not support Intl natively or via a polyfill, or if your app is already using Globalize.

Using Intl

Intl is the short name used to refer to a particular ECMAScript Internationalization API object. DevExtreme supports this API out of the box. All you need to do is set the locale:

jQuery

index.js

index.html

DevExpress.localization.locale(navigator.language);
// ...
// DevExtreme UI components are configured here
// ...

<head>
    <!-- ... -->
    <!-- DevExtreme library -->

If you want to format and localize strings, numbers, dates, and currencies automatically according to the specified locale, define the format.type property. You can also specify a currency other than USD globally. For this purpose, use the defaultCurrency or currency settings:

jQuery

JavaScript

$(function() {
    // Specifying a currency globally
    DevExpress.config({ defaultCurrency: "EUR" });

    $("#dataGridContainer").dxDataGrid({
        // ...
        columns: [{
            dataField: "Price",
            // Specifying a currency in a format definition
            format: {
                type: "currency",
                currency: "RUB"
            }
        }]

You can use structures compatible with the Intl API for value formatting. Refer to the Intl Formats section in the Value Formatting article for more information.

Using Globalize

React

IMPORTANT

React projects created with the Create React App do not support Globalize. DevExtreme React Template is one of such projects. Use Intl in these projects instead.

NOTE

If you apply CSP rules, we do not recommend that you use the Globalize technique. Use the Intl technique instead.

The following files are required to activate Globalize in your project:

Globalize library
CLDR library
CLDR data

To include these components, you can use CDN or npm.

CDN or local files

Specify the Globalize and CLDR libraries using <script> tags as shown below. In this example, the German dictionary is included. Note that the order in which you include the libraries is important. Then, set the locale using the Globalize.locale() method:

You can format and localize strings, numbers, dates, and currencies automatically according to a locale. For this, apply the format.type property. You can also use a currency other than USD (see the last example in the Using Intl topic).

In addition, you can now format values using structures accepted by numberFormatter, currencyFormatter, and dateFormatter, for example:

jQuery

JavaScript

$(function() {
    $("#dataGridContainer").dxDataGrid({
        // ...
        columns: [{
            dataField: "OrderDate",
            format: { skeleton: "yMMMd" }
        }, {
            dataField: "SaleAmount",

    },
    // ...
}
</script>

React

App.js

import React from 'react';

import 'devextreme/dist/css/dx.light.css';

import DataGrid, {
    Column
} from 'devextreme-react/data-grid';
// ...
// import dictionaries and localization modules here

Localize Custom Values

DevExtreme provides an API for localizing messages, dates, and numbers in your app.

To localize a message, add it to a dictionary as shown in the Add Strings to a Dictionary article.

To localize a custom date or number, apply a format to it as shown in the Format Custom Values article.

Right-to-Left Support

Right-to-left (RTL) support allows the UI component to adapt its content to right-to-left locales.

RTL layout can be specified for an individual UI component using its rtlEnabled property:

jQuery

JavaScript

$(function() {
    $("#sliderContainer").dxSlider({
        // ...
        rtlEnabled: true
    });
});

Angular

app.component.html

app.component.ts

app.module.ts

<dx-slider ...
    [rtlEnabled]="true">
</dx-slider>

import { Component } from '@angular/core';    

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent {
    // ...
}

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';

import { DxSliderModule } from 'devextreme-angular';

@NgModule({
    declarations: [
        AppComponent
    ],
    imports: [
        BrowserModule,
        DxSliderModule
    ],
    providers: [],
    bootstrap: [AppComponent]
})
export class AppModule { }

Vue

App.vue

<template>
    <DxSlider ...
        :rtl-enabled="true"
    />
</template>

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

import DxSlider from 'devextreme-vue/slider';

export default {
    components: {
        DxSlider
    }
}
</script>

React

App.js

import React from 'react';

import 'devextreme/dist/css/dx.light.css';

import Slider from 'devextreme-react/slider';

class App extends React.Component {
    render() {
        return (
            <Slider ...
                rtlEnabled={true}
            />
        );
    }
}
export default App;

To apply RTL to your entire application, set the same property globally using the config() function:

jQuery

JavaScript

$(function() {
    DevExpress.config({ rtlEnabled: true });
    // ...
});

Angular

app.component.ts

import { Component } from '@angular/core';
import config from 'devextreme/core/config';

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent {
    constructor() {
        config({ rtlEnabled: true });      
    }
}

Vue

App.vue

<template>
    <!-- ... -->
</template>

<script>
import config from 'devextreme/core/config';
export default {
    // ...
    created() {
        config({ rtlEnabled: true });  
    }
}
</script>

React

App.js

import React from 'react';

import config from 'devextreme/core/config';

class App extends React.Component {
    constructor(props) {
        super(props);
        config({ rtlEnabled: true });
    }

    render() {
        return (
            // ...
        );
    }
}
export default App;
