Hi,

I have a question regarding to the video you made. So I am creating an e-commerce website, and I am using dropdownlist for quantity (I could've used textbox but somehow it lose value after postback), and the list items for the dropdownlist were entered manually from collections property, not from datasource. Now, what I want to ask is that how can I retrieve the quantity value that customers choose from the dropdownlist when they click "Add to Cart" button and get direct to Cart page. For some reason, the Cart page only take quantity of 1 regardless what I choose from dropdownlist. So could you please suggest me some idea of how to solve the problem. Btw, I am using ASP.NET and VB. Thank you so much.
