在做Repeater嵌套时找不到数据源,请各位大侠帮忙看看

  <asp:Repeater id="repLM" runat="server" OnItemDataBound="repLM_ItemDataBound">
    <ItemTemplate>
        <table border="0" style="BORDER-COLLAPSE: collapse" width="98%" id="table8" class="list">
            <tr>
                <td colspan="2">
                    <div align="center">
                        <table border="0" style="BORDER-COLLAPSE: collapse" width="100%" id="table9">
                            <tr>
                                <td><%# DataBinder.Eval(Container.DataItem, "BigBoardName")%></td>
                            </tr>
                            <tr>
                                <td>
                                    <table border="0" style="border-collapse: collapse" width="100%" id="table10">
                                        <asp:Repeater id="repWZ" runat="server">
                                            <ItemTemplate>
                                                <tr>
                                                    <td><%# DataBinder.Eval(Container.DataItem, "SmallBoardName")%></a>
                                                    </td>
                                                </tr>
                                            </ItemTemplate>
                                        </asp:Repeater>
                                    </table>
                                </td>
                            </tr>
                        </table>
                    </div>
                </td>
            </tr>
            <tr>
                <td width="87%">
                </td>
                <td width="12%" class="more"><span lang="zh-cn">更多</span></td>
            </tr>
        </table>
    </ItemTemplate>
</asp:Repeater>
.cs文件代码如下:
public partial class Repeater : System.Web.UI.Page
{
     protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            GetDate();
        }
    }
    public void GetDate()
    {
        DataPro dp = new DataPro();
        repLM.DataSource = dp.GetBigBoardInfo();
        repLM.DataBind();
    }
    protected void repLM_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Repeater re = (Repeater)e.Item.FindControl("repWZ"); 
            DataRowView drv = (DataRowView)e.Item.DataItem;
            string Sid = Convert.ToString(drv["id"]);
            string sql = "select * from SmallBoard where Bid=" + Sid;
            DataPro dp = new DataPro();
            SqlDataReader dr = dp.GetSmall(sql); 
            re.DataSource=dr;
            re.DataBind();
            dr.Close();
        }
    }
}错误:
编译错误 
说明: 在编译向该请求提供服务所需资源的过程中出现错误。请检查下列特定错误详细信息并适当地修改源代码。 编译器错误信息: CS0117: “Repeater”并不包含“DataSource”的定义源错误: 行 37:             DataPro dp = new DataPro();
行 38:             SqlDataReader dr = dp.GetSmall(sql);

急用,请各位大侠帮忙!
第二个Repeater是手动写的,
审明了protected System.Web.UI.WebControls.Repeater repWZ;   也出现如上错误
