1、GridView 72般绝技快速预览：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Grid
2、View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GridView2.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：using System;using System.Data;using System.Configuration;using System.Web;using System
3、.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 /清清月儿http:/ SqlConnection sqlcon; SqlCommand sqlcom; string strCon = Data Source=
4、(local);Database=数据库名;Uid=帐号;Pwd=密码; protected void Page_Load(object sender, EventArgs e) if (!IsPostBack) bind(); protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e) GridView1.EditIndex = e.NewEditIndex; bind(); /删除 protected void GridView1_RowDeleting(object sender, GridVie
5、wDeleteEventArgs e) string sqlstr = delete from表 where id= + GridView1.DataKeyse.RowIndex.Value.ToString() + ; sqlcon = new SqlConnection(strCon); sqlcom = new SqlCommand(sqlstr,sqlcon); sqlcon.Open(); sqlcom.ExecuteNonQuery(); sqlcon.Close(); bind(); /更新 protected void GridView1_RowUpdating(object
6、sender, GridViewUpdateEventArgs e) sqlcon = new SqlConnection(strCon); string sqlstr = update 表 set 字段1= + (TextBox)(GridView1.Rowse.RowIndex.Cells1.Controls0).Text.ToString().Trim() + ,字段2= + (TextBox)(GridView1.Rowse.RowIndex.Cells2.Controls0).Text.ToString().Trim() + ,字段3= + (TextBox)(GridView1.R
7、owse.RowIndex.Cells3.Controls0).Text.ToString().Trim() + where id= + GridView1.DataKeyse.RowIndex.Value.ToString() + ; sqlcom=new SqlCommand(sqlstr,sqlcon); sqlcon.Open(); sqlcom.ExecuteNonQuery(); sqlcon.Close(); GridView1.EditIndex = -1; bind(); /取消 protected void GridView1_RowCancelingEdit(object
8、 sender, GridViewCancelEditEventArgs e) GridView1.EditIndex = -1; bind(); /绑定 public void bind() string sqlstr = select * from 表; sqlcon = new SqlConnection(strCon); SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon); DataSet myds = new DataSet(); sqlcon.Open(); myda.Fill(myds, 表); GridView1.D
9、ataSource = myds; GridView1.DataKeyNames = new string id ;/主键 GridView1.DataBind(); sqlcon.Close(); 前台主要代码： . . 3.GridView正反双向排序：效果图：点姓名各2次的排序，点其他也一样可以。后台代码：using System;using System.Data;using System.Configuration;using System.Collections;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.Htm
