GridView選中，編輯，取消，刪除
GridView正反雙向排序
GridView和下拉菜單DropDownList結(jié)合
GridView和CheckBox結(jié)合
鼠標(biāo)移到GridView某一行時改變該行的背景色方法一
鼠標(biāo)移到GridView某一行時改變該行的背景色方法二
GridView實(shí)現(xiàn)刪除時彈出確認(rèn)對話框
GridView實(shí)現(xiàn)自動編號
GridView實(shí)現(xiàn)自定義時間貨幣等字符串格式
GridView實(shí)現(xiàn)用“...”代替超長字符串
GridView一般換行與強(qiáng)制換行
GridView顯示隱藏某一列
GridView彈出新頁面/彈出新窗口
GridView固定表頭(不用Javascript只用CSS，2行代碼，很好用)
GridView合并表頭多重表頭無錯完美版（以合并3列3行舉例）
GridView突出顯示某一單元格（例如金額低于多少，分?jǐn)?shù)不及格等）
GridView加入自動求和求平均值小計
GridView數(shù)據(jù)導(dǎo)入Excel/Excel數(shù)據(jù)讀入GridView
1.GridView無代碼分頁排序：
效果圖：
1.AllowSorting設(shè)為True，ASPx代碼中是AllowSorting="True"；
2.默認(rèn)1頁10條，如果要修改每頁條數(shù)，修改PageSize即可，在ASPx代碼中是PageSize="12"。
3.默認(rèn)的是單向排序的，右擊GridView彈出“屬性”，選擇AllowSorting為True即可。

你可以使用sqlhelper,本文沒用。代碼如下：

using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
public partial class _Default : System.Web.UI.Page
{
//清清月兒http://blog.csdn.NET/21ASPNET
SqlConnection sqlcon;
SqlCommand sqlcom;
string strCon = "Data Source=(local);Database=數(shù)據(jù)庫名;Uid=帳號;Pwd=密碼";
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bind();
}
}

{
GridView1.EditIndex = e.NewEditIndex;
bind();
}
//刪除
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{

sqlcon = new SqlConnection(strCon);

sqlcon.Open();
sqlcom.ExecuteNonQuery();
sqlcon.Close();
bind();
}
//更新

{
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='"
+ ((TextBox)(GridView1.Rows[e.RowIndex].Cells[2].Controls[0])).Text.ToString().Trim() + "',字段3='"

}
//取消
protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)

GridView1.DataSource = myds;
GridView1.DataKeyNames = new string[] { "id" };//主鍵
GridView1.DataBind();

效果圖：點(diǎn)姓名各2次的排序，點(diǎn)其他也一樣可以。
