I am creating a webshop and I am currently working on the shopping cart.I keep the products that the buyer wants in the shopping cart in sessions,and a table is generated on the "ShoppingCart" page.or each product in the shopping cart a row is created with a delete button, a text box for the number, and so on.I made a button "update cart" and when I press it I want the variable "number" of each product to be replaced there the number in the row of that product.but I don't know how to address the textboxes because, for example, "textbox1.text" doesn't work.
I do not know how many text boxes are going to be in advance .. that depends on how many different products the customer add's to his shopping cart.
some help would be greatly appreciated ! Thanks in advance !
