I added a mass action in my sales->Order grid and i wanna put an action to export the selected commands in CSV file.
I add this function for mass action in app/code/local/Mage/Adminhtml/Block/Sales/Order/Grid.php
$this->getMassactionBlock()->addItem( 'Adminhtml', array('label' => $this->__('Export'), 'url' => $this->getUrl('Adminhtml/controller/action') //this should be the url where there will be mass operation ) );
But i don't know how to create controller action to my custom mass action
Thank you for help
