[Kahloon]

Hi. i want to maintain scroll position of rad panel bar. my rad panel bar is placed in page which is on auto refresh. when i scroll the bar downward of rad panel bar it goes upward on page refresh. it should not. i am trying to handle it with following code but its not working. is am missing some thing? please help.

<script type="text/javascript">
function SetScrollPositionOnlineContacts() {

                      

                     //var pane = splitter.GetPaneById("RadPanelBarRoster");

                     //document.getElementById("RadPanelBarRoster").scrollTop;

                     

                    var splitter =$find("RadSplitterBottomParent");

                    var intY =  splitter.GetPaneById("RadPanelBarRoster").scrollTop;

 

                    var date = new Date();

                    date.setTime(date.getTime() + (1 * 60 * 60 * 1000));

                    var expires = "; expires=" + date.toGMTString();

                    document.cookie = "cookieDivOnlineContacts" + "=" + intY + expires + "; path=/";

                    //document.title = intY;

                }

                function readCookieOnlineContacts(name) {

                    var nameEQ = name + "=";

                    var ca = document.cookie.split(';');

                    for (var i = 0; i < ca.length; i++) {

                        var c = ca[i];

                        while (c.charAt(0) == ' ') c = c.substring(1, c.length);

                        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);

                    }

                    return null;

                }
