Magento: GRID Important functions

Adding Edit link on a row

protected function _prepareColumns()

{

    // .... Some other code here

    $this->addColumn('action',

        array(

            'header'    => Mage::helper('catalog')->__('Action'),

            'width'     => '50px',

            'type'      => 'action',

            'getter'     => 'getId',

            'actions'   => array(

                array(

                    'caption' => Mage::helper('catalog')->__('Edit'),

                    'url'     => array(

                        'base'=>'*/*/edit',

                        'params'=>array(),

                    ),

                    'field'   => 'id'

                )

            ),

        'filter'    => false,

        'sortable'  => false,

        'index'     => 'stores',

        )

    );

}

Removing the Pager/Filter

Normally this is default on the magento grid already.

    public function __construct()

    {

        parent::__construct();

        $this->setFilterVisibility(false); // Remove Seach filtering

        $this->setPagerVisibility(false); // Remove Pager of the grid

    }

Adding Mass proccess on the Grid

    protected function _prepareMassaction()

    {

        $this->setMassactionIdField('trans_id');

        //$this->getMassactionBlock()->setFormFieldName('download');

        $this->getMassactionBlock()->addItem('delete', array(

             'label'=> Mage::helper('download')->__('Delete'),

             'url'  => $this->getUrl('*/*/massDelete'),

             'confirm' => Mage::helper('download')->__('Are you sure?')

        ));

        

        $this->getMassactionBlock()->addItem('status', array(

             'label'=> Mage::helper('download')->__('Change status'),

             'url'  => $this->getUrl('*/*/massStatus', array('_current'=>true)),

             'additional' => array(

                    'visibility' => array(

                         'name' => 'status',

                         'type' => 'select',

                         'class' => 'required-entry',

                         'label' => Mage::helper('download')->__('Status'),

                         'values' => array("x1" => "Yow", "x2"=>"secret")

                     )

             )

        ));

    }
