How to Specify each row's id with Zii Widgets Grid CGridView in Yii

When I tried to use zii.widgets.grid.CGridView in a different controller, CButtonColumn would mess up because the id would return the controller the CGridView is placed.

To specify each row's id for the CButtonColumn, you can do the following.  ^^

$this->widget('zii.widgets.grid.CGridView', array(
 'id'=>'label-grid',
 'dataProvider'=>$labelmodel,
 'columns'=>array(
  'id',
  'label',
  array(
                    'class'=>'CButtonColumn',
                    'viewButtonUrl'=>
                     'Yii::app()->controller->createUrl("label/view", 
                                       array("id"=>$data->id))',
                    'updateButtonUrl'=>
                     'Yii::app()->controller->createUrl("label/update",       
                                       array("id"=>$data->id))',
                    'deleteButtonUrl'=>
                   'Yii::app()->controller->createUrl("label/delete", 
                                      array("id"=>$data->id))',
  ),
 ),
));
