    I have used RadTreeView control in a ASP.net page and below code will add nodes  to the tree considering whether there should be child nodes.
                   if (childNodes.Count() > 0)
                            node.ExpandMode = TreeNodeExpandMode.ServerSideCallBack;

    The nodeExpand method will load the child nodes for a particular node when it is clicked.

    When a node is expanded a serverSide postbak happens and so that the member variables in the class is re-initialized. Is there a way that i can avoid this?
    I need to keep a variable value through out the node expandings till a page closes.
