GridView使用大全攻略(3)

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.Data.SqlClient;

public partial class Default5 : System.Web.UI.Page {

//清清月儿http://blog.csdn.net/21aspnet SqlConnection sqlcon;

string strCon = \北风贸易;Uid=sa;Pwd=sa\ protected void Page_Load(object sender, EventArgs e) {

if (!IsPostBack) {

bind(); } }

protected void CheckBox2_CheckedChanged(object sender, EventArgs e) {

for (int i = 0; i <= GridView1.Rows.Count - 1; i++)

{

CheckBox cbox =

(CheckBox)GridView1.Rows[i].FindControl(\ if (CheckBox2.Checked == true) {

cbox.Checked = true; } else {

cbox.Checked = false; } } }

protected void Button2_Click(object sender, EventArgs e) {

sqlcon = new SqlConnection(strCon); SqlCommand sqlcom;

for (int i = 0; i <= GridView1.Rows.Count - 1; i++) {

CheckBox cbox =

(CheckBox)GridView1.Rows[i].FindControl(\ if (cbox.Checked == true) {

string sqlstr = \飞狐工作室 where 身份证号码=''\GridView1.DataKeys[i].Value + \

sqlcom = new SqlCommand(sqlstr, sqlcon); sqlcon.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.Rows[i].FindControl(\ cbox.Checked = false; } }

public void bind() {

string sqlstr = \飞狐工作室\ sqlcon = new SqlConnection(strCon);

SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon); DataSet myds = new DataSet(); sqlcon.Open();

myda.Fill(myds, \ GridView1.DataSource = myds;

GridView1.DataKeyNames = new string[] { \身份证号码\ GridView1.DataBind(); sqlcon.Close(); } }

前台主要代码：

CellPadding=\BackColor=\BorderColor=\

OnCheckedChanged=\ Text=\全选\

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.Row.RowType == DataControlRowType.DataRow) {

//当鼠标停留时更改背景色

e.Row.Attributes.Add(\

\ //当鼠标移开时还原背景色

e.Row.Attributes.Add(\ } }

} 前台代码：
