Control order of languages outside of the Content Editor

Question

Since Sitecore 8.1 Update 2, one has been able to set the display order of languages in the Content Editor to follow the order of language items under /sitecore/system/Languages using the setting ContentEditor.SortLanguages. However, this has no impact on the order of languages from Database.GetLanguages(). Is there a way to apply this functionality to a front-end component, so that for example a language selector widget follows the language order of /sitecore/system/languages?

Answer 1

You can use LanguageComparer to apply this ordering:

var sortedLangauges = currentItem.Database.GetLanguages.OrderBy((x => x),new LanguageComparer(currentItem.Database));

This is what the ContextEditor.SortLangauges setting uses behind the scenes.
