Sorting under admin grid is not working

Question

Here is my code:

class Dolphin_Slideshow_Block_Adminhtml_Slideshow_Grid extends Mage_Adminhtml_Block_Widget_Grid
{
 public function __construct()
 {
 parent::__construct();
 $this->setId('slideshowGrid');
 $this->setDefaultSort('slideshow_id');
 $this->setDefaultDir('ASC');
 $this->setSaveParametersInSession(true);
 $this->setUseAjax(true);
 }
}

getGridUrl() function in grid.php:

public function getGridUrl()
{
 return $this->getUrl('*/*/grid', array('_current'=>true));
}

gridAction() function in controller:

public function gridAction()
{
 $this->loadLayout();
 $this->getResponse()->setBody(
 $this->getLayout()->createBlock('slideshow/adminhtml_slideshow_grid')->toHtml()
 );
}

Answer 1

try this one may be it will help you for the filter and may resolve your sorting ...

protected function _filterStoreCondition($collection, $column)
{
 if (!$value = $column->getFilter()->getValue()) {
 return;
 }
 $this->getCollection()->addStoreFilter($value);
}

Answer 2

Hmm I think You have to use this code and default sorting will work for magento $this->setUseAjax(false);
