If you encounter an issue with onkeydown event on filter fields, there is a bug in sfDataGridPlugin.

Edit sfDAtaGridFormatterPropel.class.php and add the missing “&” in url building :

$url = $object->_get(‘moduleAction’) . ‘?’ . $this->P_PAGE . ‘=1&‘ . $suffix . ‘&’ . $this->P_SORT . ‘=’ . $object->_get(‘sortBy’) . ‘&’ . $this->P_ORDER . ‘=’ . $object->_get(‘sortOrder’);
