本来呢我没想过要把这个东西转过来，可是有一天我竟然发现清清月儿的空间全空了，什么也看不到了，所以找呀找呀，终于找到了别人转过的清清月儿的东西，所以我也转过来了，就算是保存一下，权做自个儿学习了。
快速预览：
GridView无代**分页排序
GridView选中，编辑，取消，删除
GridView正反双向排序
GridView和下拉菜单DropDownList结合
GridView和CheckBox结合
鼠标移到GridView某一行时改变该行的背景色方法一
鼠标移到GridView某一行时改变该行的背景色方法二
GridView实现删除时弹出确认对话框
GridView实现自动编号
GridView实现自定义时间货币等字符串格式
GridView实现用“...”代替超长字符串
GridView一般换行与强制换行
GridView显示隐藏某一列
GridView弹出新页面/弹出新窗口
GridView固定表头(不用javascript只用CSS，2行代**，很好用)
GridView合并表头多重表头无错完美版（以合并3列3行举例）
GridView突出显示某一单元格（例如金额低于多少，分数不及格等）
GridView加入自动求和求平均值小计
GridView数据导入Excel/Excel数据读入GridView
1.GridView无代**分页排序：
效果图：
1.AllowSorting设为True，aspx代**中是AllowSorting="True"；
2.默认1页10条，如果要修改每页条数，修改PageSize即可，在aspx代**中是PageSize="12"。
3.默认的是单向排序的，右击GridView弹出“属**”，选择AllowSorting为True即可。
2.GridView选中，编辑，取消，删除：

10.GridView实现自定义时间货币等字符串格式：
效果图：
图1-未格式化前
图2-格式化后
解决方法：
在asp.net 2.0中，如果要在绑定列中显示比如日期格式等，如果用下面的方法是显示不了的
<asp :BoundField DataField='CreationDate'
DataFormatString='{0:M-dd-yyyy}'
HeaderText='CreationDate' />
主要是由于htmlencode属性默认设置为true,已防止XSS攻击，安全起见而用的，所以，可以有以下两种方法解决
Code1
//12
<asp :GridView ID='GridView1' runat='server'>3
<columns>4
<asp :BoundField DataField='CreationDate'5
DataFormatString='{0:M-dd-yyyy}'6
HtmlEncode='false'7
HeaderText='CreationDate' />8
</columns>9
</asp>10
11
//将htmlencode设置为false即可12
13
//另外的解决方法为，使用模版列14
15
<asp :GridView ID='GridView3' runat='server' >16
<columns>17
<asp :TemplateField HeaderText='CreationDate' >18
<edititemtemplate>19

附录-常用格式化公式：
{0:C} 货币；
{0:D4}由0填充的4个字符宽的字段中显示整数；
{0:000.0}四舍五入小数点保留第几位有效数字；
{0:N2}小数点保留2位有效数字；{0:N2}% 小数点保留2位有效数字加百分号；
{0:D}长日期；{0:d}短日期；{0:yy-MM-dd} 例如07-3-25；；{0:yyyy-MM-dd} 例如2007-3-25
11.GridView实现用“...”代替超长字符串：
效果图：
解决方法：数据绑定后过滤每一行即可
