Yii CArrayDataProvider sorting all columns

Question

Hi I would like to set a sorting to all fields in a CGridView without having to write them down manually. Any ideas?

$this->widget('application.widgets.GridView', array(
                'dataProvider'=>new CArrayDataProvider($offers,array(
                    'sort'=>array(
                        'attributes'=> 'AUTOMATICALLY TAKE ALL',
                    ),
                    'pagination'=>array(
                            'pageSize'=>10,
                        ),
                    )
                ),
                'enableSorting'=>true,
                ...

Now I have to write all columns(=attributes) I want to sort on. But I just want all that are defined in the grid.

You don't need asterisk feature, 'cause you can use keys from array:

$this->widget('application.widgets.GridView', array(
                    'dataProvider'=>new CArrayDataProvider($offers,array(
                        'sort'=>array(
                            'attributes'=> array_keys($offers[0]),
                        ),  
                        ...
