为了写本文，又搭工又搭料，累的2天2宿没睡觉，这篇文章实在是耗费我太多的心血，版权永远属于CSDN社区的清清月儿，请不要试图修改本文，破坏全文的完整性，希望您尊重我的劳动成果！
快速预览：
GridView无代码分页排序
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行代码，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无代码分页排序：
效果图：

1.AllowSorting设为True，aspx代码中是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代码中是PageSize="12"。
3.默认的是单向排序的，右击GridView弹出“属性”，选择AllowSorting为True即可。
2.GridView选中，编辑，取消，删除：
效果图：

后台代码：
你可以使用sqlhelper,本文没用。代码如下：

}
//删除

sqlcon = new SqlConnection(strCon);
sqlcom = new SqlCommand(sqlstr,sqlcon);
sqlcon.Open();
sqlcom.ExecuteNonQuery();
sqlcon.Close();
bind();
}
//更新
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
sqlcon = new SqlConnection(strCon);
string sqlstr = "update 表 set 字段1='"
+ ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "',字段2='"

public void bind()
{

myda.Fill(myds, "表");
GridView1.DataSource = myds;
GridView1.DataKeyNames = new string[] { "id" };//主键
GridView1.DataBind();
sqlcon.Close();
}
}
前台主要代码：

//下面这行是自动换行 GridView1.Attributes.Add("style", "word-break:break-all;word-wrap:break-word"); if (!IsPostBack) { bind();//调用数据绑定即可 } } 总之：善用CSS的word-break:break-all;word-wrap:break-word属性即可，这个属性是通用的对于顽固的南换行问题都可以解决，不局限于GridView。 12.GridView显示隐藏某一列： 本方案为月儿独创，不同于网上其他方式，我觉得用一个CheckBox更人性化，这样可以隐藏不必要的列，让用户自己选择需要出现的列，在处理多列时这是一个很好的解决方案！ 效果图： 图1-开始 <img src="http://p.blog.csdn.net/images/p_blog_csdn_net/21aspnet/286353/o_gv22.gif" alt=""> 图2-点击显示的CheckBox后 <img src="http://p.blog.csdn.net/images/p_blog_csdn_net/21aspnet/286353/o_gv21.gif" alt=""> 解决方案： public void bind() { string sqlstr = "select top 5 * from 飞狐工作室";
