Hi all,
i'm facing problems in persisting user selected check box values across multiple aspx pages in a portal(plumtree 5.0). I have a shopping cart application where i show the user a list of available products in a datagrid and a check box for each row. When the user checks couple of check box and clicks "submit", i'm saving the selected rows in a view state and loading an usercontrol. But if the user doesnot click on "submit" and navigates to any other page in the portal and then come back to the shopping cart application page, all the previous selections and the viewstate too is vanished :(. Please help me in finding a solution to persist the selected check box values so that when the user returns to the shopping cart application from any other page, i need to show the users previous selections. And i need to use only javascript, cookies or cache. i cant use session variable as it is not advisable in plumtree portal

Please help me

Thanks in advance,
Nagesh
