I m trying to get all stores of a block cms in an adminhtml page.
But something is wrong :(
Here is my code :

 class Upecom_Brandhub_Block_Adminhtml_Grid_Grid
 extends Mage_Adminhtml_Block_Widget_Grid implements Mage_Adminhtml_Block_Widget_Tab_Interface
 

 /**
 * Get tab label
 *
 * @return string
 */
 public function getTabLabel()
 
 return Mage::helper('Upecom_Brandhub')->__('Blocks');
 

 /**
 * Get tab title
 *
 * @return string
 */
 public function getTabTitle()
 
 return Mage::helper('Upecom_Brandhub')->__('Blocks');
 

 /**
 * Check if tab can be displayed
 *
 * @return boolean
 */
 public function canShowTab()
 
 return true;
 

 /**
 * Check if tab is hidden
 *
 * @return boolean
 */
 public function isHidden()
 
 return false;
 

 public function __construct()
 
 parent::__construct();
 $this->setId('myTabGridBlocks');
 $this->setUseAjax(false);
 $this->setDefaultSort('entity_id');
 $this->setDefaultDir('DESC');
 $this->setEmptyText(Mage::helper('Upecom_Brandhub')->__('No records found!'));
 
 protected function _prepareCollection()
 
 $collection = Mage::getModel('cms/block')->getCollection()
 ->addFieldToFilter("brand_id", 500)
 ->addFieldToFilter("type_block", 6);
 $this->setCollection($collection);

 return parent::_prepareCollection();
 
 protected function _prepareColumns()
 
 $this->addColumn(
 'identifier',
 array(
 'header' => Mage::helper('Upecom_Brandhub')->__('Identifier'),
 'width' => '200px',
 'index' => 'identifier',
 )
 );
 if (!Mage::app()->isSingleStoreMode()) 
 $this->addColumn('store_id', array(
 'header' => Mage::helper('cms')->__('Store View'),
 'index' => 'store_id',
 'type' => 'store',
 'store_all' => true,
 'store_view' => true,
 'sortable' => false,
 'filter_condition_callback'
 => array($this, '_filterStoreCondition'),
 ));
 
 
 

It return me all the time nothing in the store columns (but i have everything else )

I found it, I just need to add :

protected function _afterLoadCollection()

 $this->getCollection()->walk('afterLoad');
 parent::_afterLoadCollection();


protected function _filterStoreCondition($collection, $column)

 if (!$value = $column->getFilter()->getValue()) 
 return;
 

 $this->getCollection()->addStoreFilter($value);
