Fatal error in Magento while accessing categories

Error: Fatal error: Call to undefined method Mage_Adminhtml_Block_Widget::getrowurl() in C:\wamp\www\magento\app\code\core\Mage\Adminhtml\Block\Widget\Grid.php on line 1622

This problem came while accessing the categories under catalogue

The solution was simple

Go To app/code/core/Mage/Adminhtml/Block/Widget/Grid.php

public function getRowUrl($item)
{
$res = parent::getRowUrl($item);
return ($res ? $res : ‘#’);
}

replace with this one.

public function getRowUrl($item)
{
$res = parent::getUrl($item);
return ($res ? $res : ‘#’);
}
