1、GridView 经典例子19个GridView 经典例子19个快速预览：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GridV

2、iew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GridView1.GridView无代码分页排序：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

3、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：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.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using Sys

5、ed void GridView1_RowEditing(object sender, GridViewEditEventArgs e) GridView1.EditIndex = e.NewEditIndex; bind(); /删除 protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e) string sqlstr = delete from表 where id= + GridView1.DataKeyse.RowIndex.Value.ToString() + ; sqlcon = ne

6、w 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)(GridV

8、com=new SqlCommand(sqlstr,sqlcon); sqlcon.Open(); sqlcom.ExecuteNonQuery(); sqlcon.Close(); GridView1.EditIndex = -1; bind(); /取消 protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e) GridView1.EditIndex = -1; bind(); /绑定 public void bind() string sqlstr = select *

9、from 表; sqlcon = new SqlConnection(strCon); SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon); DataSet myds = new DataSet(); sqlcon.Open(); myda.Fill(myds, 表); GridView1.DataSource = myds; GridView1.DataKeyNames = new string id ;/主键 GridView1.DataBind(); sqlcon.Close(); 前台主要代码： . . 3.GridView

10、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.HtmlControls;using System.

12、 void GridView1_Sorting(object sender, GridViewSortEventArgs e) string sPage = e.SortExpression; if (ViewStateSortOrder.ToString() = sPage) if (ViewStateOrderDire.ToString() = Desc) ViewStateOrderDire = ASC; else ViewStateOrderDire = Desc; else ViewStateSortOrder = e.SortExpression; bind(); public v

13、oid bind() string sqlstr = select top 5 * from 飞狐工作室; sqlcon = new SqlConnection(strCon); SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon); DataSet myds = new DataSet(); sqlcon.Open(); myda.Fill(myds, 飞狐工作室); DataView view = myds.Tables飞狐工作室.DefaultView; string sort = (string)ViewStateSortOr

14、der + + (string)ViewStateOrderDire; view.Sort = sort; GridView1.DataSource = view; GridView1.DataBind(); sqlcon.Close(); 前台主要代码： 4.GridView和下拉菜单DropDownList结合：后台代码：using System;using System.Data;using System.Configuration;using System.Collections;using System.Web;using System.Web.Security;using Syst
