asp.net页面控件失效

[qq81357553]

一个排序的DropdownList的控件选择后调用后台代码，对下面的Repeater内的数据进行排序，不知道为什么，选择后没有用了，怎么点都一样，请哪位高手给我支点一下这是为什么？

贴点代码！

不然怎么知道哪里有问题！！

DropdownList的value是不是都一样的，一样的时候会出现这个问题的

这是前台代码
<div class="taxis">

这是后台代码
//根据图片时间哪个优先
protected void ddlPictureSort_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddlPictureSort.SelectedIndex == 0)
{

ddlSelectToDo();
}
else
{
ddlSelectToDo();
}
}

private void ddlSelectToDo()
{
if (ddlPictureSort.SelectedIndex == 1)
{
hsm.PicTime = "1";
}
DoGet(hsm);
}

protected void DisPlayInit(HouseMsg hms)
{
try
{
hms.MessageType = MessageType;
IList<HouseMsg> HouseMsgs = HouseMsgManager.GetAllHouseMsgByCon(hms);
if (HouseMsgs.Count > 0)
{
Vis(true);
PagedDataSource pdsBooks = new PagedDataSource();
pdsBooks.DataSource = HouseMsgs;
pdsBooks.AllowPaging = true;
pdsBooks.PageSize = pageSize; //显示条数
if (Pager == -1)
{
ViewState["Page"] = pdsBooks.PageCount - 1;
pdsBooks.CurrentPageIndex = Pager;
}
else
{

if ((Pager + 1) > pdsBooks.PageCount)
{
ScriptManager.RegisterStartupScript(this.UpdatePanel1, this.GetType(), "", "alert('你输入的页码有误')", true);
txtPage.Text = "";
}
else
{
pdsBooks.CurrentPageIndex = Pager;
}

}
if (pdsBooks.PageCount == 1)
{

btnGo.Enabled = false;
txtPage.Enabled = false;
}
else
{
btnGo.Enabled = true;
txtPage.Enabled = true;
}
lblCountNum.Text = "检索出" + HouseMsgs.Count + "条信息 每页" + pageSize + "条 ";
Label1.Text = (pdsBooks.CurrentPageIndex + 1).ToString() + " /" + pdsBooks.PageCount.ToString();
lblCurrentPage.Text = " 当前第 " + (pdsBooks.CurrentPageIndex + 1).ToString() + " 页 共 " + pdsBooks.PageCount.ToString() + " 页";
SetEnable(pdsBooks);


}
catch (Exception)
{
Vis(false);
}
}

请大家帮帮忙，谢谢了

ddlPictureSort_SelectedIndexChanged里排序数据再绑定到reapter

[qq81357553]

我调试了下，发现我每次选择后再后台得到的都是dropDownList中第一个值，这个该如何解决？

终于解决了，是UpdatePanel的原因
