GridView使用大全攻略(2)

ReadOnly=\

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;

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 Default3 : System.Web.UI.Page {

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

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

if (!IsPostBack) {

ViewState[\身份证号码\ ViewState[\ bind(); } }

protected void GridView1_Sorting(object sender, GridViewSortEventArgs e) {

string sPage = e.SortExpression;

if (ViewState[\ {

if (ViewState[\ ViewState[\ else

ViewState[\ } else {

ViewState[\ } bind(); }

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, \飞狐工作室\

DataView view = myds.Tables[\飞狐工作室\ string sort = (string)ViewState[\

(string)ViewState[\ view.Sort = sort;

GridView1.DataSource = view; GridView1.DataBind(); sqlcon.Close(); } }

前台主要代码：

CellPadding=\

OnSorting=\BorderStyle=\

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.HtmlControls; using System.Data.SqlClient;

public partial class Default4 : System.Web.UI.Page {

SqlConnection sqlcon;

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

DropDownList ddl; if (!IsPostBack) {

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, \飞狐工作室\ GridView1.DataSource = myds; GridView1.DataBind();

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

DataRowView mydrv = myds.Tables[\飞狐工作室\ if (Convert.ToString(mydrv[\员工性别\ { ddl =

(DropDownList)GridView1.Rows[i].FindControl(\ ddl.SelectedIndex = 0; }

if (Convert.ToString(mydrv[\员工性别\ {

ddl =

(DropDownList)GridView1.Rows[i].FindControl(\ ddl.SelectedIndex = 1; } }

sqlcon.Close(); } }

public SqlDataReader ddlbind() {

string sqlstr = \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：

CellPadding=\BackColor=\BorderColor=\

'' DataValueField=\员工性别\员工性别\
