I am setting custom registry in my module like below.

here is my controller file code.

class Childcategory extends Action

{

protected $categoryRepository;

protected $resultJsonFactory;

protected $_coreSession;

protected $_coreRegistry = null;



public function __construct(

        Context $context, 

        CategoryRepositoryInterface $categoryRepository, 

        JsonFactory $jsonFactory,

        SessionManagerInterface $coreSession,

        MagentoFrameworkRegistry $coreRegistry

        )

{

    $this->categoryRepository = $categoryRepository;

    $this->resultJsonFactory = $jsonFactory;

    $this->_coreSession = $coreSession;

    $this->_coreRegistry = $coreRegistry;

    parent::__construct($context);

}



public function execute()

{

    $parentId = $this->getRequest()->getParam('category_id');  

    $this->_coreRegistry->register('category_parent_id', $parentId);

    $category = $this->categoryRepository->get($parentId);

    $childrenData = ;

    return $this->resultJsonFactory->create()->setData($childrenData);

 }





  }

Block file code.

 class Category extends MagentoFrameworkViewElementTemplate{

protected $categoryFactory; 

protected $_storeManager;    

protected $_categoryCollectionFactory;

protected $_coreRegistry = null;

public function __construct(

    MagentoBackendBlockTemplateContext $context,

    MagentoCatalogModelCategoryFactory $categoryFactory,

    MagentoStoreModelStoreManagerInterface $storeManager,

    MagentoCatalogModelResourceModelCategoryCollectionFactory $categoryCollectionFactory,

    MagentoFrameworkRegistry $coreRegistry

)

{    

    $this->categoryFactory = $categoryFactory;

    $this->_storeManager = $storeManager;

    $this->_categoryCollectionFactory = $categoryCollectionFactory;

    $this->_coreRegistry = $coreRegistry;

    parent::__construct($context);

}



public function getCatId()

{

    $sessionId = $this->_coreRegistry->registry('category_parent_id');      

    if(isset($sessionId) && $sessionId != ''){

        return $sessionId;

    }else{

        return;

    }

    }

 }

If i try to access the registry value in my template file like below.

$registryId = $block->getCatId();

I am not getting the value, but i have set it in my controller.

Where i am doing wrong, can anyone help me please.

Change the block code like this .

class Category extends MagentoFrameworkViewElementTemplate

{

   protected $categoryFactory; 

   protected $_storeManager;    

   protected $_categoryCollectionFactory;

   protected $_coreRegistry;



   public function __construct(

    MagentoBackendBlockTemplateContext $context,

    MagentoCatalogModelCategoryFactory $categoryFactory,

    MagentoStoreModelStoreManagerInterface $storeManager,

    MagentoCatalogModelResourceModelCategoryCollectionFactory $categoryCollectionFactory,

    MagentoFrameworkRegistry $coreRegistry)

{    

    $this->categoryFactory = $categoryFactory;

    $this->_storeManager = $storeManager;

    $this->_categoryCollectionFactory = $categoryCollectionFactory;

    $this->_coreRegistry = $coreRegistry;

    parent::__construct($context);

}



public function getCatId()

{

    $sessionId = $this->_coreRegistry->registry('category_parent_id');      

    if(isset($sessionId) && $sessionId != '')

    {

        return $sessionId;

    }

    else

    {

        return;

    }

 }

}

I think you should change context class in your block. Please try this below code :

class Category extends MagentoFrameworkViewElementTemplate{

    protected $categoryFactory; 

    protected $_storeManager;    

    protected $_categoryCollectionFactory;

    protected $_coreRegistry = null;

    public function __construct(

        MagentoFrameworkViewElementTemplateContext $context,

        MagentoCatalogModelCategoryFactory $categoryFactory,

        MagentoStoreModelStoreManagerInterface $storeManager,

        MagentoCatalogModelResourceModelCategoryCollectionFactory $categoryCollectionFactory,

        MagentoFrameworkRegistry $coreRegistry

    )

    {    

        $this->categoryFactory = $categoryFactory;

        $this->_storeManager = $storeManager;

        $this->_categoryCollectionFactory = $categoryCollectionFactory;

        $this->_coreRegistry = $coreRegistry;

        parent::__construct($context);

    }



    public function getCatId()

    {

        $sessionId = $this->_coreRegistry->registry('category_parent_id');      

        if(isset($sessionId) && $sessionId != ''){

            return $sessionId;

        } else {

            return;

        }

    }

}
