Multiple checkboxlist for each item in listbox

[Priya]

I have to display a checboxlist with someitems when each item in a listbox is
selected. I have a listbox with a list of categories and when i click each
category from the listbox, the checkbox list should populate the list of
services in the checkbox list.My problem is due to postback i am not able to
retain the values of checkboxes selected earlier. I should be able to select
multiple items from listbox and multiple items from checkbox list.

Please suggest some method for doing this. I need urgent help.

Priya,

Make a class, instance that as object and save that in a session.
