Magento 2 Adminhtml – How to Get Custom Module Image URL

adminhtmlimagemagento2url

I used

<?php echo $this->getViewFileUrl('Vendor_Module::images/demo.jpg'); ?>
<?php echo $block->getViewFileUrl('Vendor_Module::images/demo.jpg'); ?>

But it's working only frontend, I want it in adminhtml block file.

I used this in renderer column of grid
File:

namespace Vendor\Module\Block\Adminhtml\Product\Renderer;

use Magento\Framework\DataObject;

class FileIcon extends \Magento\Backend\Block\Widget\Grid\Column\Renderer\AbstractRenderer
{

    public function render(DataObject $row)
    {

        echo $this->getViewFileUrl('Vendor_Module::images/demo.jpg');
        echo $block->getViewFileUrl('Vendor_Module::images/demo.jpg');

        exit;
        //return $file;;

    }
}

Use \Magento\Framework\View\Asset\Repository class

protected $_assetRepo;

public function __construct(
    ...
    \Magento\Framework\View\Asset\Repository $assetRepo,
    ...
) {
    ...
    $this->_assetRepo = $assetRepo;
    ...
}

Now, you can get image URL by

echo $this->_assetRepo->getUrl("Vendor_Module::images/demo.jpg");

Magento – Get URL of the static content folder (for backend)

Try to use:

echo $block->getViewFileUrl('Company_Helloworld::yourImage.png');

As a second argument of

\Magento\Framework\View\Element\AbstractBlock::getViewFileUrl($fileId, array $params = [])

you can set an array of next parameters: "module", "_secure", "theme", "area" and "locale"

Magento – render() must be compatible with Magento\Backend\Block\Widget\Grid\Column\Renderer\RendererInterface::render(Magento\Framework\DataObject $row)

As stated by Fabian in the comment your child class method signature is different from the parent class.

The parent method from AbstractRenderer is

public function render(DataObject $row)
{
    if ($this->getColumn()->getEditable()) {
        $result = '<div class="admin__grid-control">';
        $result .= $this->getColumn()->getEditOnly() ? ''
            : '<span class="admin__grid-control-value">' . $this->_getValue($row) . '</span>';
        return $result . $this->_getInputValueElement($row) . '</div>' ;
    }
    return $this->_getValue($row);
}

Do you notice the difference with your method?

Your method parameters is Object $row where it should be Magento\Framework\DataObject $row.
