Magento - Extending Mass Action Grid Filters (“Select All”, “Select None”) to Sales > Orders Grid

Question

I am trying to extend the filters on the Sales Order Grid. For example I would like to add "Select Pending", "Select Cancelled" etc filter in the grid.

Any help in this regard would be greatly appreciated.

For the select all option you have to overwrite or copy app/code/core/Mage/Adminhtml/Block/Sales/Order/Grid.php file with same structure in code/local folder

In the _prepareMassaction() method there is a line:

$this->getMassactionBlock()->setUseSelectAll(false);

set this to true and you have your select all.
