<asp:HyperLinkField DataNavigateUrlFormatString="DailyEdit.aspx?id={0}" Text="编辑"
                        DataNavigateUrlFields="RT_Id" />
             <asp:TemplateField ShowHeader="False">
                        <ItemTemplate>
                            <asp:LinkButton ID="lbtnDelete" runat="server" CausesValidation="False" CommandName="Del"
                                CommandArgument='<%# Eval("RT_Id") %>' Text="删除"></asp:LinkButton>
                        </ItemTemplate>
                    </asp:TemplateField>

这两个控件我想让他不可用，怎么设置(不用用户)
