Answer 1

Go to your module or extension folder then /Block/Adminhtml/Blog/Grid.php. Open this Grid.php file and search the function protected function _prepareCollection() and add the following code under this function before return parent::_prepareColumns();.
$this->addExportType('*/*/exportCsv', Mage::helper('blog')->__('CSV'));
$this->addExportType('*/*/exportXml', Mage::helper('blog')->__('XML'));
After add this code it may be looks like that:
Next, in this extension or module folder go to /controllers/Adminhtml/ and open the controller file and add the following code under the class (add the code bottom of the page before last '}')
public function exportCsvAction()
{
$fileName = 'blog.csv';
$content = $this->getLayout()->createBlock('[your-module-name]/adminhtml_[your-module-name]_grid')
->getCsv();
$this->_sendUploadResponse($fileName, $content);
}
public function exportXmlAction()
{
$fileName = 'blog.xml';
$content = $this->getLayout()->createBlock('[your-module-name]/adminhtml_[your-module-name]_grid')
->getXml();
$this->_sendUploadResponse($fileName, $content);
}
protected function _sendUploadResponse($fileName, $content, $contentType='application/octet-stream')
{
$response = $this->getResponse();
$response->setHeader('HTTP/1.1 200 OK','');
$response->setHeader('Pragma', 'public', true);
$response->setHeader('Cache-Control', 'must-revalidate, post-check=0, pre-check=0', true);
$response->setHeader('Content-Disposition', 'attachment; filename='.$fileName);
$response->setHeader('Last-Modified', date('r'));
$response->setHeader('Accept-Ranges', 'bytes');
$response->setHeader('Content-Length', strlen($content));
$response->setHeader('Content-type', $contentType);
$response->setBody($content);
$response->sendResponse();
die;
}
Now replace the [your-module-name] text with your extension or module name and save then check.
