When you edit a product in the magento administration the number of items listed in the related products, up-sells and cross-sells list is limited to 20. Also there is no possibility to change this like in felt every other grid.

I tried to fix this programmatically by creating an observer which sets the default limit to 50. The observer is called correctly (when adminhtml_block_html_before is fired) but nothing changes.

Any thoughts on this?

Ok, I could fix this.

If you're interested:

create a new file


with the following content

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="Magento\Catalog\Controller\Adminhtml\Product\Initialization\Helper\HandlerInterface" type="Magento\Catalog\Controller\Adminhtml\Product\Initialization\Helper\Plugin\Handler\Composite" />
<preference for="Magento\Catalog\Model\Locator\LocatorInterface" type="Magento\Catalog\Model\Locator\RegistryLocator"/>
<virtualType name="Magento\Catalog\Ui\DataProvider\Product\Form\Modifier\Pool" type="Magento\Ui\DataProvider\Modifier\Pool">
        <argument name="modifiers" xsi:type="array">
            <item name="related" xsi:type="array">
                <item name="class" xsi:type="string">$yourModule\Catalog\Ui\DataProvider\Product\Form\Modifier\Related</item>
                <item name="sortOrder" xsi:type="number">110</item>

and copy from vendor the Related.php to


and add the pageSize to the config Array in the method getGrid.
