Global Resources

  • 4 minutes to read

This topic describes the native ASP.NET localization technique and contains download links to localized resources for DevExpress ASP.NET controls.

Tip

In v12.1 and higher, we recommend that you localize your application with the Satellite Resource Assemblies.

You can download default and translated resources from the following link:

Download: v21.2(2021-12-21)

Resource Files

A resource file is an XML file that contains strings that can be translated into different languages. Resource files in ASP.NET have a .resx extension. Each localized resource file contains name/value pairs. You can use a text editor to customize a resource file’s string values.

LocalizationResxFile

Refer to the following topic in the Visual Studio documentation to learn more about global resource files: ASP.NET Web Page Resources Overview.

DevExpress ASP.NET products ship with a default resource file and numerous localized resource files (one for each culture).

A localized resource file name consists of the corresponding default name and a culture name, such as the following:

  • DevExpress_Web_v22.1.resx - the default resource file for DevExpress ASP.NET controls.
  • DevExpress_Web_v22.1.de.resx - a resource file for the German localization of DevExpress ASP.NET controls.

DevExpress curates resources for the following cultures: English (en) (default), German (de), Japanese (ja), and Spanish (es).

Resources for other cultures are generated by the DevExpress developer community. You should verify accuracy before incorporating resources into your software project.

Add Global Resources to an Application

Copy localized and corresponding default resource files to the App_GlobalResources folder.

LocalizationResourcesFolder

Note that if the App_GlobalResources folder contains only a localized resource file (DevExpress_Web_v22.1.de.resx), without the corresponding default resource file (DevExpress_Web_v22.1.resx), an exception will occur.

Set an Application Culture

An application culture is defined by the Culture and UICulture properties. You can specify them in the following ways.

Localize an Application for a Specific Culture (regardless of operating system settings)

Set the Culture and UICulture properties to a certain culture ID. You can specify the properties at design time or runtime.

Design Time

  • To set the culture for all pages, add the globalization element to the Web.config file. Set the Culture and uiCulture attributes.

    <system.web>
        <globalization uiCulture="es" culture="es" />
        ...
    </system.web>
    
  • To set the culture for an individual page, set the Culture and UICulture attributes of the @ Page directive.

    <%@ Page UICulture="es" Culture="es" %>
    

Runtime

Override the InitializeCulture() method to specify the Culture and UICulture properties for the page.

protected override void InitializeCulture() {
     var lang = Request.QueryString["lang"];
     if (!string.IsNullOrEmpty(lang)) {
          Culture = lang;
          UICulture = lang;
     }
}
<style type="text/css">
     .lang-btn
     {
          text-decoration: none;
     }
</style>
...
<a class="lang-btn" href="Default.aspx?lang=en">
     <img src="Images/english.png" alt="English" />
</a>
<a class="lang-btn" href="Default.aspx?lang=de">
     <img src="Images/german.png" alt="Deutsch" />
</a>
<a class="lang-btn" href="Default.aspx?lang=es">
     <img src="Images/spanish.png" alt="Spanish" />
</a>

<dx:ASPxGridView ID="ASPxGridView1" ...
</dx:ASPxGridView>

Localize an Application for Numerous Cultures (based on operating system settings)

  • Provide multiple localization sources within your application for each culture to support.
  • Set the Culture and UICulture properties to auto.

The application automatically determines the operating system’s culture information and loads the appropriate assemblies for this culture. You can set the Culture and UICulture properties in any of the ways described above.

<%@ Page UICulture="auto" Culture="auto" %>
