Asp.net - Keep Scroll Position after page refresh or reload

Question

I'm new to javascript and asp.net. I'm using linkbuttons in my page and when I click the buttons my page reloads and page scroll to the top.

I tried this script and it doesn't work.

<script type="text/javascript">
        var xPos, yPos;
        Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler);
        Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(EndRequestHandler);

        function BeginRequestHandler(sender, args) {
            xPos = document.body.scrollLeft;
            yPos = document.body.scrollTop;
        }

        function EndRequestHandler(sender, args) {
            document.body.scrollLeft = xPos;
            document.body.scrollTop = yPos;
        }
    </script>

只需在页面指令中添加MaintainScrollPositionOnPostback =“ true”
