{
    // Get the selected product details
    Button btnAddToCart = (Button)sender;
    GridViewRow row = (GridViewRow)btnAddToCart.NamingContainer;
    string productName = ((Label)row.FindControl("lblProductName")).Text;
    decimal price = Convert.ToDecimal(((Label)row.FindControl("lblPrice")).Text);

    // Add the product to the shopping cart
    ShoppingCart.AddToCart(productName, price);

We then use the FindControl method to locate the labels that display the product name and price, and extract their values. Finally, we call the AddToCart method of the ShoppingCart to add the selected product to the shopping cart.
