Actually i had override the generic class to filter the orders for sales order grid.

<preference for="MagentoFrameworkViewElementUiComponentDataProviderDataProvider" type="VendorNameModuleNameViewElementUiComponentDataProviderDataProvider"/>

It create problem for me in others grid like invoice grid , Shipment grid etc

My code is there for filter order

 protected function searchResultToOutput(SearchResultInterface $searchResult)

    {

        $arrItems = ;

        $arrItems['items'] = ;

        foreach ($searchResult->getItems() as $item) {

            $itemData = ;

            foreach ($item->getCustomAttributes() as $attribute) {

                $itemData[$attribute->getAttributeCode()] = $attribute->getValue();

            }

            $arrItems['items'] = $itemData;

            $arrItems['totalRecords'] = $searchResult->getTotalCount();

        }

        //custom code//

        $currentUser=$this->getCurrentUserId();

        $seller_order_arr = ;

        foreach ($arrItems['items'] as $row) {

            if ($row['current_seller_id'] != null){

                if (in_array($currentUser, explode(",", $row['current_seller_id']))){

                    $seller_order_arr = $row;

                }

            }

        }

        $arrItems['items'] = $seller_order_arr;

        $arrItems['totalRecords']=$this->getTotalOrder($seller_order_arr);

        // end custom code//

        return $arrItems;



    }

These lines of code work perfectly order filter as i neend. But create problem for other grids. it can be solve by 2 way.

1 ) To put if() condition for custom code it should true if request come from Sales>Order and false if request come from other pages invoice or shipment how can get order page URL for making codition.

2 ) Second is don't override the generic class . Try to filter order array an others way . In Which class::method we can filter orders array like i filter inDataProvider class.

Please guide me which is better in my case and how do that .
Thanks in advance

As per, my idea first one is not a good idea to override a class.

My suggestion to change the data provider the class of this grid
.

means changes like

<dataProvider class="MagentoFrameworkViewElementUiComponentDataProviderDataProvider"

to

<dataProvider class="{Vendor}{ModuleName}UiElementUiComponentDataProviderDataProvider"

that is the best process.

Code of New UI Data provider class:

<?php



namespace StackExchangeMagentoUiElementUiComponentDataProvider;



class DataProvider extends MagentoFrameworkViewElementUiComponentDataProviderDataProvider {



    protected function searchResultToOutput(MagentoFrameworkApiSearchSearchResultInterface $searchResult) {

        $arrItems = ;

        $arrItems['items'] = ;

        foreach ($searchResult->getItems() as $item) {

            $itemData = ;

            foreach ($item->getCustomAttributes() as $attribute) {

                $itemData[$attribute->getAttributeCode()] = $attribute->getValue();

            }

            $arrItems['items'] = $itemData;

            $arrItems['totalRecords'] = $searchResult->getTotalCount();

        }

        //custom code//

        $currentUser = $this->getCurrentUserId();

        $seller_order_arr = ;

        foreach ($arrItems['items'] as $row) {

            if ($row['current_seller_id'] != null) {

                if (in_array($currentUser, explode(",", $row['current_seller_id']))) {

                    $seller_order_arr = $row;

                }

            }

        }

        $arrItems['items'] = $seller_order_arr;

        $arrItems['totalRecords'] = $this->getTotalOrder($seller_order_arr);

        // end custom code//

        return $arrItems;

    }



}

Also override sales_order_grid.xml and past datasource tag in this file.
