TreeView doesn’t retain state

On my master page, I have a TreeView and on my content pages I have an update panel. I am not sure if the update panel effects this, but my treeview loses the collapsible states across postbacks.

The following code uses UpdatePanel and maintains treeview state.
As you can see there are two buttons
one is in UpdatePanel
second is out of UpdatePanel

                    ExpandLevel=\"2\" BorderColor=\"Silver\" BorderWidth=\"1px\" Height=\"330px\" Width=\"260px\"
            Padding=\"2px\" FadeEffect=\"true\" DisplayBar=\"true\" BarBackgroundImage=\"$bar_grey\">


                                            BarImageUrl=\"$office2003_delete\">



                                            Value=\"Inbox\" ToolTip=\"3 item(s) unread\">
                                                    Value=\"John Smith\">


                                            Value=\"Search Folders\" BarImageUrl=\"$office2003_flag_red\" CanBeSelected=\"False\">





                            RowHeight=\"16px\" Padding=\"1px;4px;4px;1px\" />
                            BorderWidth=\"1px\" ForeColor=\"White\" Padding=\"0px;3px;3px;0px\" />

The treeview saves state as it should.

Could you please provide an example that will cause the error and that we can debug locally.

Thanks.
