I want to add field sort order in admin grid and in frontend part (sort by). I make module "news" and want to sort my news by title.

Please guide me how to do it

protected function _prepareCollection()
{
    $collection = Mage::getModel('mdnews/news')->getCollection();
    $this->setCollection($collection);
    return parent::_prepareCollection();
}
protected function _prepareColumns()
{
    $helper = Mage::helper('mdnews');

    $this->addColumn('news_id', array(
    'header' => $helper->__('News ID'),
    'index' => 'news_id',
    'width' => '100px',
    ));

   $this->addColumn('title', array(
    'header' => $helper->__('Title'),
    'index' => 'title',
    'type' => 'text',
   ));

   $this->addColumn('category', array(
    'header' => $helper->__('Category'),
    'index' => 'category_id',
    'options' => $helper->getCategoriesList(),
    'type'  => 'options',
    'width' => '150px',
   ));

   $this->addColumn('created', array(
    'header' => $helper->__('Created'),
    'index' => 'created',
    'type' => 'date',
   ));

   return parent::_prepareColumns();
}

add these two in _construct this will do in admin..

public function __construct()
   { 
$this->setDefaultSort('title'); //default field to sort
$this->setDefaultDir('ASC'); //sort by ASC ot DESC

}
