The built-in localization mechanism in Silverlight allows you to localize any string resource used by the standard RadWindow control. Once translated you might use your resources in Silverlight projects without changing anything.

RadWindow can be translated in one of the following supported languages using the framework’s localization mechanism:
This section lists the unique localization string identifiers, called resource keys. They are used in the RadWindow control to define the localization string's key and translation.
