Localization
Updated on May 7, 2026
To localize RadImageEditor to display control text and messages in a specific language:
-
All required classes for localization are defined in Telerik.WinControls.UI.Localization namespace.
-
Start by creating a descendant of the ImageEditorLocalizationProvider class.
-
Override the GetLocalizedString(string id) method and provide a translation for the label and user messages. If a translation is not provided, the default value will be returned. This behavior is guaranteed by the call of the base GetLocalizedString method in the default clause of the switch statement in the example.
Below is a sample implementation of an English localization provider:
