I will have a TreeView control where the user can add/delete nodes, then click the Save button, which will save the data entered into the database.
Normally, I would be saving the TreeView data inside session object while the user is editing it, but the way our web servers work, the session can not be relied on (I have been told NOT to use it ). Aside from that what options do I have? Please note that we don't want to use Ajax option where every node is saved upon editing in the background either for usability reasons. A user needs to be able to edit the tree and then save it all at once.
Can I store the TreeView data inside cookies while the tree is being edited? Any other ideas? Thanks in advance.
