I have a custom webpart that either shows a list of products or the detailed view of a single product depending on the configuration options. On the landing page (/Home.aspx) I have the list view on the right column with some general content in the central column. When you click a product I want it to go to the product page (/Product.aspx) where the right column still has a list of items but the central column has the detailed view of the product selected.
I have this working without a problem when you click a product in the list while on the Product.aspx page but I can't get it to work when clicking a product from Home.aspx.
I know cross page PostBacks aren't available in Visual Web Parts. Is it possible to do this without using session state or a query string?
