Is it possible to localize DataListItem Name and Description?

[Nikkelmann]

In the backoffice it is possible to localize properties by prepending the localization key with a hash sign, eg. "#area_key".
However, this does not seem to work with the DataListItems, nor does the "area/key" format (https://docs.umbraco.com/umbraco-cms/extending/language-files#using-the-language-keys).

Is there a way to get the DataListItem Name and Description values localized?

The setup I've tried so far

The property on the doctype with the added localization keys:

The rendered form in the backoffice, where the property is translated, but not the names of the values:

The enum with the DataListItem, where I've tried with three different localization key formats:

Note: I've also tried with @ in front of the key.

The DataType setup:

The translations in /config/lang/{language}.user.xml:

Hi @Nikkelmann.

There's nothing in the Data List code that will detect and localize the keys. The reason being that each of the data-sources are responsible for their own data-items. With the Enum data-source, the optional DataListItemAttribute is very basic, using the literal strings.

Currently, the potential options are to either roll-your-own custom data-source that injects Umbraco's ILocalizedTextService... or to hook into the SendingContentNotification handler to localize the labels (again using the ILocalizedTextService).

Now since you've raised this question, I would be open to adding this feature to the Enum data-source, I'm thinking along the lines of introducing some kind of UmbracoLocalizeAttribute (for want of a better name) - as opposed to overloading DataListItemAttribute with scenarios. All things for me to consider. 🤔
