    'pager'=>array(
        'maxButtonCount'=>Yii::app()->params['maxButtonCount'],
    ),

How can i get $data->user->name to be label name of button.

Answer 1

$data does not exist in that context

Try:

'label' => '$data->user->name'

Answer 2

label is supposed to be a fixed string, not an expression. You will have to extend CButtonColumn so it'll feature a labelExpression that gets evaluated. The code for the url property should give you a fairly good idea.

Answer 3

Try with double quotes:

'label' => "$data->user->name"
