如何在checkboxlist中设置对listitem的关注 [英] how to set focus on listitem within checkboxlist

问题描述

你好专家，

我在复选框列表中有十多个列表项（autopost back设置为true表示复选框列表），如果我检查任何listitem第二/第三/第四列表项焦点被设置回来首先列出复选框列表中的项目。是否有任何解决方案专注于检查项目？

谢谢



这里是代码

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

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;           
        }

推荐答案

'）;
int index = int .Parse（checkedBox [checkedBox.Length - 1 ]）;
if （chk_Bhid.Items [index] .Selected）
{
value = chk_Bhid.Items [index] .Value;
}

'); int index = int.Parse(checkedBox[checkedBox.Length - 1]); if (chk_Bhid.Items[index].Selected) { value = chk_Bhid.Items[index].Value; }

我自己找到了解决方案

I have found Solution myself

<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%>') != null) { xPos =
