Answer 1

Use below code for store filter

protected function _filterStoreCondition($collection, $column){
    $array = explode(",",$column->getFilter()->getValue());
    if(is_array($array)){
        foreach($array as $child){
            if (!$value = $child) {
                return;
            }
             $collection->addFieldToFilter('store_id',array(
                        array('finset'=> array('0')),
                        array('finset'=> array($value)),
                    ));
            return $this;
        }
    }
    else{
        if (!$value = $column->getFilter()->getValue()) {
            return;
        }
        $collection->addFieldToFilter('store_id',array(
                    array('finset'=> array('0')),
                    array('finset'=> array($value)),
                ));
        return $this;
    }
 }

Use below code instead of $this->getCollection()->addStoreFilter($value);

$collection->addFieldToFilter('store_id',array('in',$value));
