Inject Magento\Framework\Data\CollectionFactory in constructor for $this->collectionFactory

$bestsalecollection = $this->_collectionFactory->create()->setModel(
            \Magento\Catalog\Model\Product::class
        )->addStoreFilter(
            $storeId
        );

        $productCollection = $this->productcollectionFactory->create();
        $sellercollection=$productCollection->addFieldToFilter('current_user_id',array('eq'=>1));
        $filter_product=$this->collectionFactory->create();

        foreach ($sellercollection as $allProduct){
            foreach ($bestsalecollection as $bestSale){
                if($allProduct->getEntityId()==$bestSale->getProductId()){
                    $varienObject = new \Magento\Framework\DataObject();
                    $varienObject->setData($bestSale->getData());
                    $filter_product->addItem($varienObject);
                }
            }
        }
    $this->setCollection($filter_product);
    return parent::_prepareCollection();

  • $this->setCollection($filter_product); is not usefull ? – HaFiz Umer May 20 '19 at 11:17
  • It can also be used. But for that also, use need to create that variable as collection factory and push product array using addItem before set collection – aravind May 20 '19 at 11:25
  • Have you tried above method?did you get any error? – aravind May 20 '19 at 11:26
  • Sir i am confuse where you setCollection() ? – HaFiz Umer May 20 '19 at 11:27
  • If you want to create your own custom collection then setCollection can be used.. – aravind May 20 '19 at 11:33
