[Yii Framework] Add a link in CGridView

When we using CGridView in Yii, we may want to a link as a column. So in common sense, we will use CLinkColumn to do that, as these code:

<?php $this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider'=>$dataProvider,
    'columns'=>array(
        array(
            'name'=>'username',
            'class'=>'CLinkColumn',
            'labelExpression'=>'$data->username',
            'urlExpression'=>'Yii::app()->createUrl("admin/user", array("id"=>$data->id))',
        ),
    ),

)); ?> 

But we can not sort the username with this way. Thanks for Yii, we can use another way to do it. Here are the code:

<?php $this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider'=>$dataProvider,
    'columns'=>array(
        array(
            'name' => 'username',
            'type' => 'raw',
            'value' => 'CHtml::link($data->username,Yii::app()->createUrl("admin/user/view", array("id"=>$data->id)))'
        ),
    ),

)); ?>  

Have fun with Yii!
