请问我下面的后台代码为什么数据绑不到前台数据控件上去呢？请高人指点啊！
前台代码：
   <asp:ListView ID="ListView1" runat="server" OnItemDataBound="ListView1_ItemDataBound">
        <LayoutTemplate>
            <asp:PlaceHolder ID="itemPlaceholder" runat="server"></asp:PlaceHolder>
        </LayoutTemplate>
        <ItemTemplate>
               <div>
                    <asp:HyperLink runat="server" ID="hpProImg">
                        <asp:Image runat="server" ID="imgPro" Width="103" Height="80" border="0" />
                    </asp:HyperLink>
                </div>
                    <asp:Repeater ID="PTypeList" runat="server" EnableViewState="false">
                        <HeaderTemplate>
                        </HeaderTemplate>
                        <ItemTemplate>
                                <%# Eval("Name") %>
                        </ItemTemplate>
                        <FooterTemplate>
                        </FooterTemplate>
                    </asp:Repeater>
        </ItemTemplate>
     </asp:ListView>
后台数据绑定：

  protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
    {
        if (e.Item.ItemType == ListViewItemType.DataItem)
        {
            Repeater Detail = (Repeater)e.Item.FindControl("PTypeList");
            Image imgPro = (Image)e.Item.FindControl("imgPro");
            HyperLink hpProImg = (HyperLink)e.Item.FindControl("hpProImg");

            DataView dv = ShopFunc.GetCommHot(m_TypeID, m_Num).DefaultView;
            if (dv.Count > 0 && !StringUtil.IsEmpty(dv[0]["PicSmall"].ToString()))
            {
                imgPro.ImageUrl =  dv[0]["PicSmall"].ToString();
                hpProImg.NavigateUrl = "../" + string.Format(UrlFormat.GetUrlFormat("ProductUrl"), dv[0]["ProductId"].ToString());
                Detail.DataSource = dv;
            }
            else
            {
                imgPro.ImageUrl = "../Images/Blank.gif";
            }

            Detail.DataBind();
        }
    }
