# CollectionsChanged

> Occurs when the project's table collections change.

## Definition

* **Type:** Event
* **Namespace:** [Unity.Localization.Editor](/engine/7000.0/script-reference/unity/localization/editor.md)
* **Assembly:** UnityEditor

```csharp
[AutoStaticsCleanup]
public static event Action CollectionsChanged
```

### Remarks

Raised after a [ResourceTableCollection](/engine/7000.0/script-reference/unity/localization/editor/resourcetablecollection.md) is created, imported, or deleted, and after an edit that windows other than the one making it need to see, such as renaming a key or changing its metadata. Editor UI listens to this to refresh itself.
