gridview自动增长列和为删除列添加确认对话框

1.gridview自动增长列

                        <asp:TemplateField HeaderText="序号">
                            <ItemTemplate>
                                <asp:Label runat="server" Text='<%# Container.DataItemIndex +1%>'></asp:Label>
                            </ItemTemplate>
                        </asp:TemplateField> 

2.为删除列添加确认对话框

目前已知的最简洁的方法，注意使用对话框Gridview-->Columns-->编辑，在删除按钮的那一列属性里面，把DeleteText属性设为

<div id="de" onclick="JavaScript:return confirm('确定删除吗？')">删除</div> 

使用Image
在deleteText里: <img src="../images/trash.gif" border="0" onclick="JavaScript:return confirm('Are you sure you want to delete this item?')">
