Hi,

For an application I have to save the treeview checked items state. When users navigate away from the page and they come back the state of the selection must be persisted. I try to do this to save the collection of the checked items in a cookie or a Session.Item

The Session.Item is set every time on the OnNodeCheck event.
When I come back I set the checked nodes from the Session.Item but i think every time I set a checkbox the OnNodeCheck event is fired. Is that correct? What would be the best approach to keep the Checked state in memory so I can reproduce the treeview correctly?

BR,
Marc

Hi Marc,


Checkout the code library which might help in persisting the checkbox state after postback.
