I have a custom grid, and I wanna remove the highlighted parts from it: 
I wanna remove only from my custom grid. What would be the best way?
This is my Grid.php:
public function __construct()
{
parent::__construct();
$this->setFilterVisibility(false);
$this->setId('integrationGrid');
$this->setDefaultSort('entity_id');
$this->setDefaultDir('ASC');
$this->setSaveParametersInSession(true);
$this->setUseAjax(true);
}
public function _prepareLayout()
{
$this->unsetChild('reset_filter_button');
$this->unsetChild('search_button');
}
protected function _prepareCollection()
{
$collection = Mage::getModel('novapc_allnations/integration')->getCollection();
$this->setCollection($collection);
parent::_prepareCollection();
return $this;
}
protected function _prepareColumns()
{
$this->addColumn(
'integrate_option',
array(
'header' => Mage::helper('novapc_allnations')->__('Integrate'),
'index' => 'integrate_option',
'type' => 'text',
'filter' => false,
'renderer' => 'Novapc_Allnations_Block_Adminhtml_Integration_Renderer_Syncproducts',
'sortable' => false
)
);
$this->addColumn(
'updated_at',
array(
'header' => Mage::helper('novapc_allnations')->__('Updated at'),
'index' => 'updated_at',
'width' => '300px',
'type' => 'datetime',
'filter' => false,
'renderer' => 'Novapc_Allnations_Block_Adminhtml_Integration_Renderer_Updatedat',
'sortable' => false
)
);
$this->addColumn(
'first_update',
array(
'header' => Mage::helper('novapc_allnations')->__('First update'),
'index' => 'first_update',
'width' => '300px',
'type' => 'datetime',
'filter' => false,
'renderer' => 'Novapc_Allnations_Block_Adminhtml_Integration_Renderer_Createdat',
'sortable' => false
)
);
return parent::_prepareColumns();
}
/**
* get the grid url
*
* @access public
* @return string
* @author .
*/
public function getGridUrl()
{
return $this->getUrl('*/*/grid', array('_current'=>true));
}
protected function _afterLoadCollection()
{
$this->getCollection()->walk('afterLoad');
parent::_afterLoadCollection();
}
protected function _prepareMassaction()
{
$this->setMassactionIdField('entity_id');
$this->getMassactionBlock()->setFormFieldName('allnations_integration');
$this->getMassactionBlock()->addItem(
'integratecat',
array(
'label' => Mage::helper('novapc_allnations')->__('Integrar Categorias'),
'url' => $this->getUrl('*/*/massCategory')
)
)
->addItem(
'integrateprod',
array(
'label' => Mage::helper('novapc_allnations')->__('Integrar Produtos'),
'url' => $this->getUrl('*/*/massIntegrateProduct')
)
)
->addItem(
'updatestock',
array(
'label' => Mage::helper('novapc_allnations')->__('Atualizar Estoque'),
'url' => $this->getUrl('*/*/massUpdateStock')
)
)->setUseSelectAll(false);
return $this;
}
