Serial Numbers (item counts) in GridView

How-tos

serial number, grid items count

```php
Yii::import('zii.widgets.grid.CGridColumn');

class CounterColumn extends CGridColumn {
 
 


}We need to set starter value for the counter so, we have


 
```php private $i = 0;     public function init()
 
{      $pager=$this->grid->dataProvider->pagination;      if($pager->currentPage==0) {     $this->i=0;     } else {      $this->i=$pager->currentPage*$pager->pageSize;     }
 
        
 
    }
 
} ``` We need to use display the value, so we have
 
```php public function renderDataCellContent($row, $data) {   {      $this->i++;
 
      echo $this->i;     }
```Yii::import('zii.widgets.grid.CGridColumn');

class CounterColumn extends CGridColumn {  { private $i = 0; public function init()
 
    { $pager=$this->grid->dataProvider->pagination; if($pager->currentPage==0) { $this->i=0; } else { $this->i=$pager->currentPage*$pager->pageSize; }         
 
} public function renderDataCellContent($row, $data) { // $row number is ignored     { $this->i++;  
 
echo $this->i;
}
}```php
$this->widget('zii.widgets.grid.CGridView', array(
    'id'=>'categories-grid',     'dataProvider'=>$model->search(),     'filter'=>$model,     'columns'=>array(         array(         'header'=>'Sr #',          'class'=>'CounterColumn' ),
 
),
 
'id',         'name', array(
 
     array(
 
'header'=>'Actions',             'class'=>'CButtonColumn',          )
 
)); ```
