In React components, the key value of translations is sometimes in CamelCase, sometimes in PascalCase. Impossible to use the resx definitions as a basis for loading the correct keys, which change randomly from one component to another. Example in your documentation : https://ej2.syncfusion.com/react/documentation/common/globalization/localization 'grid': { 'EmptyRecord': 'Keine Aufzeichnungen angezeigt', }, 'pager': { 'currentPageInfo': '{0} von {1} Seiten', }
