GridView无代码分页排序

1、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：using System;using System.Data;using System.Configuration;using System

2、.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.Data.SqlClient;public partial class _Default : System.Web.UI.Page /清清月儿/21aspnet SqlConnection sqlcon; SqlComma

7、d void GridView1_RowCancelingEdit(object 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

8、.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;usi

9、ng 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 Default3 : System.Web.UI.Page/清清月儿的博客/21aspnet SqlConnection sqlcon; string strCon

11、SortOrder.ToString() = sPage) if (ViewStateOrderDire.ToString() = Desc) ViewStateOrderDire = ASC; else ViewStateOrderDire = Desc; else ViewStateSortOrder = e.SortExpression; bind(); public void bind() string sqlstr = select top 5 * from 飞狐工作室; sqlcon = new SqlConnection(strCon); SqlDataAdapter myda

12、= 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)ViewStateSortOrder + + (string)ViewStateOrderDire; view.Sort = sort; GridView1.DataSource = view; GridView1.DataBind(); sqlco

13、n.Close(); 前台主要代码： 4.GridView和下拉菜单DropDownList结合：效果图：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

17、ose(); public SqlDataReader ddlbind() string sqlstr = select distinct 员工性别 from 飞狐工作室; sqlcon = new SqlConnection(strCon); SqlCommand sqlcom = new SqlCommand(sqlstr, sqlcon); sqlcon.Open(); return sqlcom.ExecuteReader(); 前台主要代码： asp:DropDownList ID=DropDownList1 runat=server DataSource= DataValueFie

18、ld=员工性别 DataTextField=员工性别 5.GridView和CheckBox结合：效果图：后台代码：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 System.Web.UI.HtmlControls;using System.Da

22、con.Open(); sqlcom.ExecuteNonQuery(); sqlcon.Close(); bind(); protected void Button1_Click(object sender, EventArgs e) CheckBox2.Checked = false; for (int i = 0; i = GridView1.Rows.Count - 1; i+) CheckBox cbox = (CheckBox)GridView1.Rowsi.FindControl(CheckBox1); cbox.Checked = false; public void bind

23、() 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, tb_Member); GridView1.DataSource = myds; GridView1.DataKeyNames = new string 身份证号码 ; GridView1.Data

24、Bind(); sqlcon.Close(); 前台主要代码： 6.鼠标移到GridView某一行时改变该行的背景色方法一：效果图：做法：双击GridView的OnRowDataBound事件；在后台的GridView1_RowDataBound()方法添加代码，最后代码如下所示：protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) int i; /执行循环，保证每条数据都可以更新 for (i = 0; i GridView1.Rows.Count; i+) /首先判断是否是数据行 if (e

27、可以更新 /for (i = 0; i GridView1.Rows.Count; i+) / / /首先判断是否是数据行 / if (e.Row.RowType = DataControlRowType.DataRow) / / /当鼠标停留时更改背景色 / e.Row.Attributes.Add(onmouseover, c=this.style.backgroundColor;this.style.backgroundColor=#00A9FF); / /当鼠标移开时还原背景色 / e.Row.Attributes.Add(onmouseout, this.style.backgroundColor=c); / / /如果是绑定数据行 if (e.Row.RowType = DataControlRowType.DataRow) /鼠标经过时，行背景色变 e.Row.Attributes.Add(onmouseover, this.style.backgroundColor=#E6F5FA); /鼠标移出时，行背景色变 e.Row.Attributes.Ad
