repeater 动态显示隐藏列

今天做了一个repeater 动态显示隐藏列的功能。。查了一下网上的方法，然后自己按照别人的方法写了如下的列子： 

   <%--   用于显示隐藏列--%>
                                        <%switch (hdfStatus.Value)
                                          {
                                              case "" :
                                              case "1": 
                                        %>
                                         <td>
                                            <b><a ></asp:Label>
                                        </td>
                                        <%break;
                                          }%>
