主标签可以正常选择，次标签首个选中是默认选中

当选择www,eee,rrr,ttt标签的时候会自动刷新回默认标签，后台事件没有执行

只有选择最后一个标签时，就会执行一次后台SelectIndexChange事件，但是再点击前面的www,eee,rrr,ttt标签时又不执行后台数据了，并且选中的项又跳回了最后一个标签。

后台代码

    {

        if (!IsPostBack)

        { radioOnLoad(); }

    }



    public void radioOnLoad ()

    {

        switch (RadioButtonList1Lable.SelectedValue)

        {

            case "心情":

                radioDataBind("心情");

                break;

            case "随笔":

                radioDataBind("随笔");

                break;

            case "相册":

                radioDataBind("相册");
