                    'filter' => $func,
                    'value' => function ($model, $key, $index, $column) {
                        return $model['RoleName'];
                    },
                ],

                [
                    'label' => 'Actions',
                    'content' => function($model) use ($from, $to) {
                        return Html::a('<span class="btn btn-sm btn-primary">View</span>', Yii::$app->request->baseUrl . '/controller/function/?userid=' . $model['UserId'] . '&from=' . $from . '&to=' . $to, [
                                    'title' => Yii::t('app', 'View'),
                                    'data-pjax' => '0',
                        ]);
                    }
                ],
            ],
        ]);

Thanks in advance :)

Yeah. That is because roles in yii2 rbac are stored in items, and there is a separate table that is assigning roles to users. Your code is way too tight to guess what is going on at the back..but I'm guessing you're making a user index? Anyway:

• You need Yii::$app->authManager->getRoles(); to get the array of roles.

• You need to join the auth_assignment table in your searchModel

  if($this->role){ $query->join('LEFT JOIN','auth_assignment','auth_assignment.user_id = client_id') ->andFilterWhere(['auth_assignment.item_name' => $this->role]); }

• Make sure your searchModel contains role and that attribute is safe.
