Adding a Add to Cart button in Swift_ProductListGridView.cshtml

I'm trying to add a add to basket button on the Swift_ProductListGridView.cshtml (I know, bad idea performance wise, but as we all know sometimes Customer is king :-))

The button works and adds the right quantiry of products to the basket.

However then the page reloads and the Facet template generates an error.

I suspect i must change something in the form definition/url parameter, but I'm not sure what and how to do that.

The url parameter is defined as: string url = Dynamicweb.Context.Current.Request.RawUrl;

The form is defined as:

<form method="post" action="@url" class="flex-fill">
<input type="hidden" name="redirect" value="false" />
<input type="hidden" name="ProductId" value="@product.Id" />
  <input type="hidden" name="cartcmd" value="add" />
After cliking the add cart button the error is:

Error executing template "Designs/Swift/Paragraph/Swift_ProductListFacets.cshtml"

Nevermind this thread, I will use the Product List View instead!

Hi Justin

Customer might be king, but they are also not ecommerce specialists. They might feel they need a feature because they think it is good. But often it is bad because it will decrease conversions and cause them a loss of money. I have not met a lot of customer that likes that... When explaining with known facts what is good ideas and what is bad ideas from a UX and conversion rate perspective (and not feelings) it usually is explainable.

But glad you found a solution.
