I am using the WebExplorerBar in a MasterPage for navigation and I need to maintain the state (both the expanded and selected items) of the WebExplorerBar between postbacks and page navigations.  I looked at this example:

http://www.infragistics.com/community/forums/t/47906.aspx

There were 2 issues with this example:

1) It didn't handle group child items having child items themselves

2) It did not save/restore the selected node properly (expanded was working as long as group child items did not have child items)

I wrote a class to save the state (expanded/selected), which I store in the session and use to keep the state of the WebExplorerBar.  I works fine for the Expanded property of all of the nodes, but the Selected issue from the example remains (the selected node in the WebExplorerBar sometimes works, sometimes it defaults to the first item, sometimes it selects the previously selected item.)  I have verified that my code for saving/setting the state works properly for Expanded and also works properly for Selected (it only sets one node to be Selected and it is the previously selected node).

It seems like something on the client side is changing the highlighted node after I have set the Selected property (expanded state of all node is restored correctly).  Can someone help me with this?

// Class to save state

public class WebExplorerBarItemState
    {
        public bool NodeState { get; set; }
        public bool Selected { get; set; }
        public List<WebExplorerBarItemState> ItemStates = new List<WebExplorerBarItemState>();
    }

    /// <summary>

                groupState.NodeState = group.Expanded;
                groupState.Selected = group.Selected;
                _groupStates.Add(groupState);
