Actions:

    $dataProvider = $searchModel->search(Yii::$app->request->queryParams);
//  The key (or keyField) must be filled, if the key is not equal to primary key.        
    $dataProvider->key = 'uuid';// for ActiveDataProvider 
//  $dataProvider->keyField = 'uuid';// for ArrayDataProvider 

    return $this->render('index', [

}
    
public function actionDetail($id, $advanced = false)
{
    $model = $this->findModel($id);

    $dataProvider = new ArrayDataProvider([
        'allModels' => $model->events,
    ]);

    return $this->renderAjax('_detail', [
        'dataProvider' => $dataProvider,
        'advanced' => $advanced,
        'id' => $id,
    ]);
}

view/_detail.php:
