We are trying to use a custom localization for RadEditor Dialogs. We created RadEditor.Dialogs.en-GB.resx, RadEditor.Dialogs.fr-CA.resx … files and we set the “LocalizationPath” and “Language” properties. This is working fine for all cultures but not for “en-US”. The dialogs are displayed without text for "en-US" culture and it seems it cannot see the resx file for US. Can you please help with this issue?
