Localizing RadAsyncUpload

The localization support for RadAsyncUpload lets you translate the user interface, or simply adapt a few strings. This article provides information on how you can use localization with the RadAsyncUpload control.

Localization Property

The Localization property specifies the strings that appear in the runtime user interface of RadAsyncUpload. By changing the values of each named sub-property, you change the appearance of the string the upload uses:

<telerik:radasyncupload id="RadAsyncUpload1" runat="server" localization-select="Select zip file" />

Async Upload Localization

note

This technique is useful when customizing some of the messages of a particular instance. The messages are not shared between upload instances. A complete translation using this approach is not appropriate.

 

Property Name Default Value Description
Add Add Sets the text of the Add button.
Remove Remove Sets the text of the Remove button.
Select Select Sets the text of the Select button.
DropZone Drop files here Sets the text of the DropZone that appears when the file is about to be dropped (added Q3 2012 SP1).

Global Resource Files

The primary means for localization in ASP.NET is to use resource files. Resource files are simple XML files that can be easily edited and transferred to other applications. You can use resource files to change the default (English) localization for RadUAsyncpload that is stored in the Telerik.Web.UI assembly.

To create a global resource file to localize the upload follow these steps:

  1. Create the App_GlobalResources folder in the root of your web application.

  2. Copy the default resource RadAsyncUpload.resx file into it. This file can be found in the App_GlobalResources folder of the directory where you installed the RadControls.

  3. Make a copy of the file and rename the copy so that its name contains the Culture Identifier. The resource files used by RadAsyncUpload follow a strict naming convention: RadAsyncUpload.<Culture Identifier>.resx

note

The Culture Identifier consists of a language code followed by a dash and the country code. Example: “en-US”, “fr-CA” and so on.

For example* RadAsyncUpload.fr-CA.resx*. Both files should be present in the App_GlobalResources folder:

  1. Edit the strings using the Visual Studio editor or your favorite text editor. Customize strings just as you would set the Localization property.
caution

Make sure that the ReservedResource message is preserved. It is used for identification purposes and is never displayed.

You can now switch the RadAsyncUpload so that it uses your new resource file by setting the Culture property:Culture
