1 .js代码判断删除的function Delete(id,right)
{
    if (right=="f")
    {
        alert("对不起，您没有会员的权限");
        return false;
    }
    var l;
    if(id < 0)
    {
        l = GetAllChecked();   //得到选择项的id
        if(l == "")
        {
            alert("您没有选择要删除的信息!");
            return;
        }
    }
    else
    {
        l = id;
    }
    if(confirm('确定要永久删除您所选择的信息吗?'))
    {
         SendAjax("del",l); //调用下面的函数 2
     }
}

function SendAjax(op,id)
{
    var param = "Option="+ op +"&ID="+ id;
    var options={
        method:'post',
        parameters:param,
        onComplete:
        function(transport)
    {
      var retv=transport.responseText;
  onRcvMsg(retv);
}        }
new  Ajax.Request('MemberAllList.aspx',options);  //传入下面页面执行的方法
}
3. protected void del(string sid)
        {
            if (!PowerTree.PowerPass.isPass("008001003", PowerTree.PowerPanel.PowerType.del))
            {
                bp = new BasePage();
                bp.PageError("对不起，你没有删除普通会员的权限！", "../Default.aspx");
            }
            string[] id = sid.Split(',');
            int ln = id.Length;
            int n = 0;
            for (int i = 0; i < id.Length; i++)
            {
                if (!id[i].Trim().Equals(""))
                {
                    try
                    {
                        if (datau.Delect(Convert.ToInt32(id[i])) == 1)
                        {
                            data.Delete(Convert.ToInt32(id[i]));
                            datau.Delect(Convert.ToInt32(id[i]));
                            fk.ID = Convert.ToInt32(id[i]);
                            ff.Delect(fk);
                        }
                        n++;
                    }
                    catch
                    {
                        continue;
                    }                }
            }
            Response.Write(n + "%成功删除" + n + "条信息！");}

问题：删除信息的时候页面不刷新，所以当时删除的信息不能及时的显示，我将我的绑定方法ListDataBind(); 放在执行成功之后，它会将我的所有html的代码输出
我想可能是我用了response.write();
但是我不知道现在我怎么让这个删除后页面刷新？？？？？？？
帮助？？？
