RadNumericBox supports automatic localization of its strings, using resource files. The setup is simple and this article
describes the steps needed to provide localization for this control.
Following these steps to localize RadNumericBox:
At the root level of your application, create a strings folder. It will host the localization resources.
Create a separate folder for each language that you want to support and name it after the corresponding locale, e.g. fr-FR.
Go to C:\Program Files (x86)\Telerik\UI for Windows 8 HTML QX 201X\strings\en and copy
the radnumericbox.resjson file. Paste it in each language's folder.
The correct folder structure should look like this:
Translate the provided messages to the corresponding language and save the file.
The control will use the current culture of the application, which would be either the user default culture (if supported), the
default culture provided in package.appxmanifest or the one that you have provided by overwriting the primary
language of the application. For more information on the application's way of handling cultures, click to read the MSDN resource,
"How to manage language and region", at the end of this article.
