If you install new magento or upgrade your magento with latest version or you got the error like below: Fatal error: Call to undefined method Mage_Adminhtml_Block_Widget::getrowurl() in C:\xampp\htdocs\magento\app\code\core\Mage\Adminhtml\Block\Widget\Grid.php on line 1622 Read this for the solution that workes for me: Go To app/code/core/Mage/Adminhtml/Block/Widget/Grid.php Look at on line no 1620 on magento 1.5.01 public function getRowUrl($item) { $res = parent::getRowUrl($item); return ($res ? $res : '#'); } And replace this line $res = parent::getRowUrl($item); to $res = parent::getUrl($item); So your new function look like this: public function getRowUrl($item) { $res = parent::getUrl($item); return ($res ? $res : '#'); } [JWD-Magento-Development]
