I am facing an issue in My custom grid. I have added 'Export to CSV' in Grid and it is working fine.

Issue is I have added a row total in grid but in Exported CSV, total is actually the total of all rows rather then the total of filtered rows.

I am using a below code to add the Total row for a specific column. This code is working in Grid Block but not working in GridExport Block.

protected function _afterLoadCollection()

{

    $collection = $this->getCollection();



    $salesTotal = 0;



    foreach ($collection as $rowData) {

        $salesTotal += (float)$rowData->getPrice() * (float)$rowData->getQuantity();

    }

    $this->setTotals(new MagentoFrameworkDataObject(

        array( 'subtotal'=>$salesTotal )

    ));

    return $this;

}

It seems that, _afterLoadCollection() never call in GridExport Block although both Blocks are extending the same class as

class Grid extends MagentoBackendBlockWidgetGridExtended { ... }

class GridExport extends MagentoBackendBlockWidgetGridExtended { ... }

Grid and CSV samples are attached for reference.

Grid
CSV

I have resolved the issue. There are basically 2 functions in Extended Grid Block

namespace MagentoBackendBlockWidgetGrid;

// other stuff

class Extended extends MagentoBackendBlockWidgetGrid implements MagentoBackendBlockWidgetGridExportInterface

{

    // other code

    public function getCsvFile()

    {

        // doesn't call _afterLoadCollection() function

    }



    // other code

    public function getCsv()

    {

         $csv = '';

         $this->_isExport = true;

         $this->_prepareGrid();

         $this->getCollection()->getSelect()->limit();

         $this->getCollection()->setPageSize(0);

         $this->getCollection()->load();

         $this->_afterLoadCollection(); // That I needed

         // ...

     }

     // ...

}

So I have used getCsv() function in my Controller as:

public function execute()

{

    $resultPage = $this->_resultPageFactory->create();



    $fileName = 'Referral_'. date('Y-m-d h:i:s') . '.csv';

    $exportBlock = $resultPage->getLayout()

        ->createBlock(

            'VendorModuleBlockAdminhtmlReferralsGridExport'

        );

    return $this->_fileFactory->create(

        $fileName,

        $exportBlock->getCsv(), // this fucntion

        DirectoryList::VAR_DIR

    );

}

Although, I am not sure what's the difference between getCsv() and getCsvFile()
