AutoDetect()

Creates a language selector that reads current language selection and enables replacement and fallback language handling.

Declaration
public static LanguageSelector AutoDetect()
Returns
Type Description

Using AutoDetect without parameters will result in no master language fallback handling.

AutoDetect(Boolean)

Creates a language selector that reads current language selection and enables fallback languages

Declaration

Parameters
Type Name Description
System.Boolean enableMasterLanguageFallback

Enable master language as a last resort for fallback instead of filtering a page
Returns
Type Description

The prefered language branch (overrides user choice)
System.Boolean enableMasterLanguageFallback

Enable master language as a last resort for fallback instead of filtering a page
Returns
Type Description
LanguageSelector

A language selector object

LoadLanguage(LanguageSelectorContext)

Selects language branch based on a page link only, used for example when creating new pages
