hello experts,
I have more then ten list items in a checkboxlist (autopost back set to true for checkboxlist), If i check any listitem 2nd/3rd/4th list item focus is set back to first list item in the checkbox list. Is there any solution that focus stays at the checked item?
Thanks

here is code

C#

string value = string.Empty;
        string result = Request.Form["__EVENTTARGET"];
        string[] checkedBox = result.Split('$'); 
        int index = int.Parse(checkedBox[checkedBox.Length - 1]);
        if (chk_Bhid.Items[index].Selected)
        {
            value = chk_Bhid.Items[index].Value;           
        }

Do you have to postback on every checkbox click?

<script type="text/javascript">
             var xPos, yPos;
             var prm = Sys.WebForms.PageRequestManager.getInstance();
             function BeginRequestHandler(sender, args) {
                 if ($get('<%=Div1.ClientID%>') != null) {
                     xPos = $get('<%=Div1.ClientID%>').scrollLeft;
                     yPos = $get('<%=Div1.ClientID%>').scrollTop;
                 }
             }
             function EndRequestHandler(sender, args) {
                 if ($get('<%=Div1.ClientID%>') != null) {
                     xPos = $get('<%=Div1.ClientID%>').scrollLeft = xPos;
                     yPos = $get('<%=Div1.ClientID%>').scrollTop = yPos;
