如何清除repeater中的删除二个字呢？

HTML code

  <asp:Repeater runat="server" ID="Repeater1" OnItemCommand="Repeater1_ItemCommand"                                    OnItemDataBound="Repeater1_ItemDataBound"> <td onclick="displayctrl2('WZXXMC_<%# Eval("sortindex") %>',this);" id="WZXXMC_<%# Eval("sortindex") %>">                                                <div class="txtlabelClass" id="txtlabel_WZXXMC_<%# Eval("sortindex") %>">                                                    <asp:Label ID='Grid_Label_WZXXMC' RowIndex='<%# Eval("sortindex") %>' runat="server"                                                        Text='<%# Bind("WZXXMC") %> '></asp:Label>                                                </div> <td style="text-align: center">                                                <a href="#" onclick="clearData(<%# Eval("sortindex") %>)">                                                    <asp:Label ID='label_Delete' Text='删除' runat="server"></asp:Label></a>                                            </td>

如何WZXXMC的值为空，如何才能做到不显示 "label_Delete"呢？

[解决办法]

<%# string.IsNullOrEmpty(Eval("WZXXMC").ToString())?"":"删除"%>
