# ListChangeHandler

> Receives the localized values whenever a localized string list resolves or changes.

## Definition

* **Type:** Delegate
* **Namespace:** [Unity.Localization](/engine/6000.7/script-reference/unity/localization.md)
* **Assembly:** UnityEngine.LocalizationRuntimeModule

## Remarks

Subscribe a handler through [ILocalizedStringList.ListChanged](/engine/6000.7/script-reference/unity/localization/ilocalizedstringlist/listchanged.md). The list instance passed to the handler is a copy, so the handler can keep or edit it freely.
