超链接回发后维护滚动位置

Question

I have tried numerious different approaches to my problem, but none of them seem to work out. I basically activate and deactivate users using a asp.net hyperlink and the problem is as soon as you do that, the page scrolls back up because of the postback it creates, so it will be annoying to scroll back down if you have a list of 1000 users. Here is the code iv'e been trying out without success!

            // I use this variable for navigating the url for my hyperlink
            var toggleUrl = "AdminListUsers.aspx?column=" + (IsClicked.FirstOrDefault().Key ?? "Name") + "&direc=" + (IsClicked.FirstOrDefault().Value) + "&a=chstat&q=" + id.ToString() + "&d=" + disabled + "&z=" + Server.UrlEncode(txtSearchFor.Text); 

            var hl = new HyperLink(); //These hyperlinks are the same
            hl.Text = status;
            hl.Style.Add(HtmlTextWriterStyle.Color, (disabled ? "red" : "green"));
            hl.NavigateUrl = toggleUrl;
            hl.Attributes.Add("onclick", "saveScroll(this);return true;");
            cell.Controls.Add(hl);
            tr.Cells.Add(cell);

            cell = new TableCell();
            cell.Width = new Unit("10%");

            cell.Controls.Add(new LiteralControl("<nobr>"));

            var linkbtn = new HyperLink //These hyperlinks are the same
            {
               //Here as you can see are my attributes for the hyperlink
                NavigateUrl = toggleUrl,
                Width = 16,
                Height = 16,
                CssClass = disabled ? "user-status-disabled" : "user-status-enabled"
            };
            linkbtn.Attributes.Add("id", "aButton_" + id);

            ScriptManager.RegisterStartupScript(Page, typeof(Page), "ScrollToADiv", "setTimeout(scrollToDiv, 1);", true); // Not working
            linkbtn.Attributes.Add("onclick", "window.scrollTo(0, location.hash);"); // Not working either

            cell.Controls.Add(linkbtn);
            cell.Controls.Add(new LiteralControl("&nbsp; "));

As per my understanding, you could set the MaintainScrollPositionOnPostback to true in any of the below three ways.

1. Web.config Level => pages maintainScrollPositionOnPostBack="true" />
2. Page Level => <%@ Page MaintainScrollPositionOnPostback="true" %>
3. Code Level => Page.MaintainScrollPositionOnPostBack = true;

Hope this Helps!!

EDIT Code help for the comment below (assuming jQuery is being used):

$(".user-status-enabled").on("click", function() {
     var $this = $(this);
     var scrollPosition = $this.scrollTop();
     $this.attr("href", $this.attr("href") + "&scrollPosition=" + scrollPosition);
});

And on the target screen, access this scrollPosition from Query String and set the scroll position on dom Ready
