Ben magento2 içinde modül oluşturmaya çalışıyorum, şimdi yönetici tarafında ızgara sayfası oluşturmak sıkışmış, herhangi biri zaten yaptıysanız bana bildirin
Yanıtlar:
Öncelikle ızgara için sayfa oluşturmanız gerekir. Magento2 yeni sayfa örneğine bakın
Sonra bu sayfa görünümü / adminhtml / layout / samplegrid_index_index.xml için ui bileşenini mizanpaja ekleyin
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">

.
Son olarak Kılavuz Ui Bileşeni ile yapılır Aşağıda filtre seçeneği ile ızgara için gereken adımlar ve dosyalar bulunmaktadır.
İlk olarak, dizin eylem düzeni xml oluşturmamız gerekir:
Sugarcode \ test \ görünümü \ adminhtml \ düzeni \ test_lists_index.xml
<?xml version="1.0"?>
<!--
/**

<update handle="styles"/>
<body>
<referenceContainer name="content">
<uiComponent name="test_lists_listing"/>
</referenceContainer>
</body>
</page>
İkinci dosya ui bileşeni xml, bu xml kullanmamız gerekmiyorsa Grid.php her şey sadece bu xml'den yapılandırılır
Kod \ Sugarcode \ Testi \ görünümü \ adminhtml \ ui_component \ test_lists_listing.xml

Buraya kadar filtre, sıralama seçeneği ve toplu eylem yapılır ve onun iyi çalışıyor ama tam metin arama sabit değilse tam ızgara hazır çalışmıyor herhangi biri bu sorunu düzeltmek için bana yardımcı olabilir.
