GridView的选中,编辑,删除功能实现用例 gridview取消默认选中

(摘自:http://hi.baidu.com/xihzh/blog/item/9651af11a73c017aca80c4b3.html)

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.csdn.net/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" />
