这段代码为什么在ＩＥ７下就能显示数据．在ＩＥ６中就不能显示数据

    <form id="form1" runat="server">
    <div style=" width:785px; margin:0 auto; text-align:center; ">
        <uc1:top ID="Top1" runat="server" />
        <div style=" width:785px; margin:0 auto; text-align:center; ">

<div style="background:url(images/nbj.gif); width:785px; height:40px"><div style="margin-top:20px; text-align:left"><img src="images/mxqy.jpg" /></div></div>
</div>
<div style=" width:785px; margin:0 auto; text-align:center; margin-top:8px; height:100%">
    <asp:DataList ID="DataList1" runat="server" RepeatColumns="5" RepeatDirection="Horizontal" Width="780px">
    <ItemTemplate>
      <div style="width:156px; text-align:left; font-size:14px;line-height:25px"><a href="<%# DataBinder.Eval(Container.DataItem,"url")%>" target="_blank" style="font-size:14px; color:#000"><%# DataBinder.Eval(Container.DataItem,"title")%></a></div>
    </ItemTemplate>
    </asp:DataList> <webdiyer:aspnetpager id="AspNetPager1" runat="server" horizontalalign="Center" onpagechanged="AspNetPager1_PageChanged"
        width="100%" PageSize="200"></webdiyer:aspnetpager></div>
    </div>
    <uc2:bottom ID="Bottom1" runat="server" />
    </form> --------------------编程问答-------------------- CS代码是
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            string region = Request.QueryString["region"];
            ViewState["region"] = region;
            int totalOrders = CatalogDataBase.GetOrder("P_GetOrderNumber3",region);
            AspNetPager1.RecordCount = totalOrders;
            bindData(region);
        }
    }

    void bindData(string region)
    {
        DataList1.DataSource = DataBase.ExecuteReader(CommandType.StoredProcedure, "P_GetPagedOrdersQiye",
           new SqlParameter("@startIndex", AspNetPager1.StartRecordIndex),
           new SqlParameter("@endIndex", AspNetPager1.EndRecordIndex),
           new SqlParameter("@region", region)
           
           );
        DataList1.DataBind();

    }
    protected void AspNetPager1_PageChanged(object src, EventArgs e)
    {
        string region = ViewState["region"].ToString();
        bindData(region);
    }


为什么在IE6中会没有数据? --------------------编程问答-------------------- 顶上去!!!! --------------------编程问答-------------------- <div style=" width:785px; margin:0 auto; text-align:center; margin-top:8px; height:100%"> 
try remove height:100% --------------------编程问答-------------------- 还是不行呀..不知道为什么

补充：.NET技术 ,  ASP.NET
