关于GridView设置编辑或不可编辑的相关问题！

当系统标识为用户自定义的时候修改删除可编辑，否则不可编辑！由于设置权限问题，所有在gridview控件中有一个系统标识的掩藏列：

<Columns>
                                        <asp:TemplateField>
                                            <ItemTemplate>
                                                <input type="checkbox" />详细&nbsp;</asp:HyperLink>
                                              

                                                <%#Eval("Function_IsSys").ToString() == "2"?
                                                        "<asp:HyperLink ID='Delete' Enabled='false' runat='server' ToolTip='删除'  NavigateUrl='#' ><span style='cursor:pointer' onclick=DelInfoById(" + Eval("FUNCTION_ID") + ",XC_Web.Frame.SystemManage.ModulFunction,'/Frame/SystemManage/ModulFunction.aspx')><img src='../skins/sky/icon/del.gif' border='0'/>删除</span></span></asp:HyperLink>" :
                                                                                                            "<asp:HyperLink ID='Delete' runat='server' NavigateUrl='#' ToolTip='删除' disabled='disabled' ><img src='../skins/sky/icon/del.gif' border='0'/>删除</asp:HyperLink>"
                                                    %>
                                            </ItemTemplate>
                                            <HeaderStyle Font-Bold="False" />
                                            <ItemStyle HorizontalAlign="Center" Width="22%" />
                                        </asp:TemplateField>
                                    </Columns>
