 <ItemStyle Width="10%" />
                                            <ItemTemplate>
                                                <asp:LinkButton ID="LinkButton1" runat="server" CommandName="delete" CssClass="blue_12b_a"
                                                    OnClientClick="return confirm('确认要删除此行信息吗？')">删除</asp:LinkButton>
                                            </ItemTemplate>
                                        </asp:TemplateColumn>这个是设计部门的代码

一般还是要删除数据库你要动态构建TABLE也可以断点到dg_Add.DataSource = dt_DataBase;看看dt_DataBase的值。。还有用viewstate保存DataTable比较好
