本文介绍如何在ASP.NET中使用GridView控件实现数据的分页、排序、编辑、删除等功能，并提供了详细的代码示例。

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.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http://blog.youkuaiyun.com/21aspnet
SqlConnection sqlcon;
SqlCommand sqlcom;
string strCon = "Data Source=(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, GridViewDeleteEventArgs e)
{
string sqlstr = "delete from 表 where id='" + GridView1.DataKeys[e.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 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='" + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[2].Controls[0])).Text.ToString().Trim() + "',字段3='" + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[3].Controls[0])).Text.ToString().Trim() + "' where id='" + GridView1.DataKeys[e.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 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.DataSource = myds;
GridView1.DataKeyNames = new string[] { "id" };//主键
GridView1.DataBind();
sqlcon.Close();
}
}
前台主要代码：
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4" ForeColor="#333333" GridLines="None" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit">
<FooterStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
<Columns>
<asp:BoundField DataField="身份证号码" HeaderText="用户ID" ReadOnly="True" />
<asp:BoundField DataField="姓名" HeaderText="用户姓名" />
<asp:BoundField DataField="员工性别" HeaderText="性别" />
<asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />
<asp:CommandField HeaderText="选择" ShowSelectButton="True" />
<asp:CommandField HeaderText="编辑" ShowEditButton="True" />
<asp:CommandField HeaderText="删除" ShowDeleteButton="True" />
</Columns>
<RowStyle ForeColor="#000066" />
<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" />
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
</asp:GridView>
