Magento: Add radio/checkbox button in custom column in Admin Grid

Add custom column in admin Grid which will show radio/checkbox button. I know this is weird, but some people need this as a requirement. Here I will show you how you can have radio button or checkbox button that you can have directly in your grids.


For radio button,
$this->addColumn('some_id', array(
            'header_css_class' => 'a-center',
            'header'    => Mage::helper('adminhtml')->__('Some Header'),
            'type'      => 'radio',
            'html_name' => 'items[]',
            'align'     => 'center',
            'value'    => array('1')
        ));

For checkbox button,
$this->addColumn('some_id', array(
            'header_css_class' => 'a-center',
            'header'    => Mage::helper('adminhtml')->__('Some Header'),
            'type'      => 'radio',
            'field_name' => 'items[]',
            'align'     => 'center',
            'values'    => array('1','2')
        ));

Further, in Form.php you can add this below code to have by default behavior and onclick behaviour:

$fieldset->addField('some_id', 'checkbox', array(
          'checked'    => $this->getSomeId()==1 ? 'true' : 'false',
          'onclick'    => 'this.value = this.checked ? 1 : 0;'
));

Hope this helps some frustrated mind!
