title: JQuery ASP.NET MVC drag and drop shopping cart doesnt retain cart items when navigating to different category
body: <p>I am very new to ASP.NET MVC and JQuery, I have built a e-commerce website in ASP.NET MVC, JQuery &amp; C#. I used the Drag &amp; Drop model from  <a href="http://www.codeproject.com/Articles/301620/Drag-Drop-Shopping-Cart-Using-Asp-net-MVC-and-JQuery" rel="nofollow">http://www.codeproject.com/Articles/301620/Drag-Drop-Shopping-Cart-Using-Asp-net-MVC-and-JQuery</a> which is great. I have modified the JQuery to meet all of my needs in regards to data retrieval, posting back data etc. </p>
  
  <p>The problem I am having is I have different product categories that use my products.cshtml (view) so when a user wants to add more items to the current cart and the navigate to a new category all the existing items in the cart are removed when the postback occurs. My question is how do I keeps the current items in the cart when navigating to a different category. </p>
