 Alternatively, if you're viewing records in a modal action, check out the [Actions documentation](../../actions/prebuilt-actions/view#customizing-data-before-filling-the-form).
 
+## Lifecycle hooks
+
+Hooks may be used to execute code at various points within a page's lifecycle, like before a form is filled. To set up a hook, create a protected method on the View page class with the name of the hook:
+
+```php
+use Filament\Resources\Pages\ViewRecord;
+
+class ViewUser extends ViewRecord
+{
+    // ...
+
+    protected function beforeFill(): void
+    {
+        // Runs before the disabled form fields are populated from the database. Not run on pages using an infolist.
+    }
+
+    protected function afterFill(): void
+    {
+        // Runs after the disabled form fields are populated from the database. Not run on pages using an infolist.
+    }
+}
+```
