I have a grid with an admin UI component. There is a custom collection in the column. But when I apply the filter for that column then it shows me an error.

Please check my code below for the ui_componenet listing XML file.

<column name="sample_info" class="Namespace\Sampleproduct\Ui\Component\Listing\Column\SampleInfo">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="filter" xsi:type="string">text</item>
                    <item name="sortable" xsi:type="boolean">false</item>
                    <item name="dataType" xsi:type="string">text</item>
                    <item name="bodyTmpl" xsi:type="string">ui/grid/cells/html</item>
                    <item name="label" xsi:type="string" translate="true">Sample Request Information</item>
                    <item name="sortOrder" xsi:type="number">4</item>

Please check my data provider code below,

namespace Namespace\Sampleproduct\Ui\Component\Listing\Column;

class SampleInfo extends \Magento\Ui\Component\Listing\Columns\Column
    protected $jsonHelper;

     * CustomerInfo constructor.
     * @param \Magento\Framework\View\Element\UiComponent\ContextInterface $context
     * @param \Magento\Framework\View\Element\UiComponentFactory $uiComponentFactory
     * @param \Magento\Framework\Json\Helper\Data $jsonHelper
     * @param array $components
     * @param array $data
    public function __construct(
        \Magento\Framework\View\Element\UiComponent\ContextInterface $context,
        \Magento\Framework\View\Element\UiComponentFactory $uiComponentFactory,
        \Magento\Framework\Json\Helper\Data $jsonHelper,
        array $components = [],
        array $data = []
        $this->jsonHelper = $jsonHelper;
        parent::__construct($context, $uiComponentFactory, $components, $data);

    public function prepareDataSource(array $dataSource)
            foreach($dataSource['data']['items'] as &$item){
                $sampleInfo  = '<b>Product: </b>'.$item['product_name'].'<br/>';
                $sampleInfo .= '<b>Materials & Colors: </b><br/>';
                try {
                    $sampleColors = $this->jsonHelper->jsonDecode($item['colors']);
                    foreach($sampleColors as $materialName=>$colorData) {
                        $sampleInfo .= $materialName.' - '.implode(', ',$colorData).'<br/>';
                } catch (\Exception $e) {
                    $materials = explode(',',$item['material']);
                    if(!empty($materials[0])) {
                        $sampleInfo .= $materials[0].' - ';
                    $sampleInfo .= $item['colors'].'<br/>';

                $item['sample_info'] = $sampleInfo;
        return $dataSource;

When I search for any string, it throws the error. Please check the attached screenshot, enter image description here

Please let me know how can I filter the custom column with the custom collection.

Thanks. Your help would be appreciated.!!!!

In Your DataProvider File, there is a function named : addFilter(\Magento\Framework\Api\Filter $filter)

You have to modify that a little bit, I have added the sample code here, In which you can replace your attribute_code from which you want to filter the values with collection.

public function addFilter(\Magento\Framework\Api\Filter $filter)
        if (isset($this->addFilterStrategies[$filter->getField()])) {
                    [$filter->getConditionType() => $filter->getValue()]
        } else {
            // Custom code for Filter
            if ($filter->getField() == 'sample_info') {
                if ($filter->getValue() == 'your_filter_value') {
                    $filterData = [
                            'attribute' => 'your_attribute_name',
                            'null' => true
                } else {
                    $filterData = [
                            'attribute' => 'your_attribute_name',
                            'eq' => $filter->getValue()
            // End
            else {
  • Yes, it works. I have modified the code as per my requirements. Thank You.!!! Mar 23, 2022 at 8:55
  • Great to hear from your side !! Mar 23, 2022 at 9:14

try to add column by below method.




  • No, i don't have issue related to add custom column in the grid. You can see there are multiple fields merged in single column and due to that, i am not able to filter. Mar 23, 2022 at 7:16
