I want to remove Add To Cart button at category page. but I don't want to use template file. I did it for product view page using event.

 $layout = $observer->getEvent()->getLayout();
 $layout->getUpdate()->addUpdate('<referenceBlock name="product.info.addtocart.additional" remove="true"/>');
 $layout->getUpdate()->load();
 $layout->generateXml();

its working fine; But how can i remove button from category page?

Thanks.

You can use core_layout_render_element Event from the MagentoFrameworkViewLayout::renderElement() method in order to add an Observer. In the observer you can you preg_replace or analogue to remove generated Add to Cart button.

There is similar question and however event name is outdated: Modify Product Listing 'Add to Cart' button

Hope it helps.

If we look at this module-catalogviewfrontendtemplatesproductlist.phtml around line 80 There is function $_product->isSaleable() which then again call to isSalable() function of MagentoCatalogModelProduct.

There are two events in it catalog_product_is_salable_before and catalog_product_is_salable_after. Depending on your need you can modify it.

I used catalog_product_is_salable_after event to hide Add to Cart button

namespace NamespaceModuleObserverFrontend;

use MagentoFrameworkEventObserver;
use MagentoFrameworkEventObserverInterface;

class classname implements ObserverInterface

 public $request;

 public function __construct(
 MagentoFrameworkAppRequestHttp $request
 ) 
 $this->request = $request;
 

 public function execute(Observer $observer)
 
 if ($this->request->getFullActionName() == 'catalog_category_view')
 

 $product = $observer->getEvent()->getProduct();
 $saleble = $observer->getEvent()->getSalable();

 if($product->getTypeId() == 'customProductType')
 
 $saleble->setIsSalable(false);
 $salable = $product->getStatus() == MagentoCatalogModelProductAttributeSourceStatus::STATUS_ENABLED;
 if ($salable && $product->hasData('is_salable')) 
 $salable = $product->getData('is_salable');
 
 $product->setIsSaleable($salable); 
 
 
 return $this;
 

Though this will add In Stock or Out of Stock in place of Add to Cart.

You can achieve this by following CSS tricks.

Add below CSS rules in skin/theme/child/css or skin/theme/default/css

/*add to cart button*/
.products-grid .button.btn-cart 
 display : none ;
