Hello!

For ajax calls to an action i use renderPartial instead of render, and then i use Yii::app()->end();

I also see you are trying to output the $search variable what it is not being created, try output $model instead

your action should finish like that:




 public function actionViewDetails()

        {

                $classList = $_POST['classList'];

                //var_dump($classList);exit;

                $model = StudentDetails::model()->findByAttributes(array('class'=>$classList));

                $this->renderPartial('_view',array('search'=>$model));//var_dump($search);exit;

                Yii::app()->end();

        }

Hope it helps!
