  <tr>

                    立项状态:
                </td>
                <td>
                    <asp:ListBox ID="ddlStatus" runat="server" SelectionMode="Multiple" multiple="multiple" style="200px">
                    </asp:ListBox>
                    <input type="hidden" id="hdStatus" runat="server" />
                </td>
            </tr>
            <tr>
                <td align="right">
                    审核状态:
                </td>
                <td>               
                    <asp:ListBox ID="ddlEmailVerifyStatus" runat="server" SelectionMode="Multiple" multiple="multiple" style="200px">
                    </asp:ListBox>
                      <input type="hidden" id="hdEmailVerifyStatus" runat="server" />
                </td>
            </tr>

后台直接使用hd的值，值比如为001,002,003
