GridView如何分页代码

以下是分页的各个按钮的代码，比如说页面是Order.aspx，那么以下就是Order.aspx.cs代码 using System;

using System.Data;

using System.Configuration; using System.Collections; using System.Web;

using System.Web.Securi

以下是分页的各个按钮的代码，比如说页面是Order.aspx，那么以下就是Order.aspx.cs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.OleDb;

public partial class admin_MainOrder {

protected static int iPageCount =0;//所有记录一共分成几页，这个是系统自动算出来的 protected static int curPage = 1;//当前显示第几页

protected static bool IsFirst = false;//当前页是否是首页 protected static bool IsLast = false;//当前页是否是尾页 protected static int iPageSize = 10;//每页显示几条 protected void Page_Load(object sender, EventArgs e) {

if (!Page.IsPostBack) BindControls(); }

void BindControls() {

if (Request.QueryString[\"Page\"] != null)

curPage = Convert.ToInt32(Request.QueryString[\"Page\"]); else

curPage = 1;

string SQL = \"SELECT Q1.*,(SELECT Name FROM Hard WHERE ID=Q1.Q_Hard) AS Q_Hard1,\"+

\"(SELECT TypeName FROM QuestionType WHERE ID=Q1.Q_Type) AS Q_Type1,\"+

\"(SELECT TypeName FROM SortType WHERE ID=Q1.Q_Sort) AS Q_Sort1 FROM Questions Q1\";

DataView odv=new DataView();

odv = DBFun.CreateAccessView(SQL);

//分页 PagedDataSource这个对象是系统自定义的，直接调用就可以实现分页了 PagedDataSource opds = new PagedDataSource();

opds.DataSource = odv; //获取数据源

opds.AllowPaging = true; //是否在数据绑定中启用分页 opds.PageSize = iPageSize; //每页显示几条

opds.CurrentPageIndex = curPage - 1;//获取当前页索引，这句必须加上

lblCurrentPage.Text = \"第\" + curPage.ToString() + \"页/共\"+opds.PageCount+\"页 \"; iPageCount = opds.PageCount;//共几页系统自动算出来 IsFirst = opds.IsFirstPage; IsLast = opds.IsLastPage;

gridQuestion.DataSource = opds;//gridQuestion是GridView名 gridQuestion.DataBind();//绑定 }

//跳转

protected void lnkGoTo_Click(object sender, EventArgs e) {

if (txtPage.Text.Trim() == \"\") return;

string sAoto = txtPage.Text.Trim().ToString(); if (!Fun.IsInteger(sAoto)) return;

if (Convert.ToInt32(sAoto) > 0 && Convert.ToInt32(sAoto) <= iPageCount) {

string slnkGoto = Request.CurrentExecutionFilePath + \"?Page=\" + sAoto; Response.Redirect(slnkGoto); } }

//更新

protected void lnkUpdate_Click(object sender, EventArgs e) {

if (txtShow.Text.Trim() == \"\") return;

string sAoto = txtShow.Text.Trim().ToString(); if (!Fun.IsInteger(sAoto)) return;

if (Convert.ToInt32(sAoto)>0 && Convert.ToInt32(sAoto) < 51) {

iPageSize = Convert.ToInt32(sAoto);

Response.Redirect(Request.CurrentExecutionFilePath); } }

//首页

protected void lnkFirst_Click(object sender, EventArgs e) {

if (iPageCount != 0) {

string slnk = Request.CurrentExecutionFilePath; Response.Redirect(slnk); } }

//上一页

protected void lnkPrev_Click(object sender, EventArgs e) {

if (iPageCount != 0 && !IsFirst) {

string slnk = Request.CurrentExecutionFilePath Convert.ToString(curPage-1);

Response.Redirect(slnk); } }

//下一页

protected void lnkNext_Click(object sender, EventArgs e) {

if (iPageCount != 0 && !IsLast) {

string slnk = Request.CurrentExecutionFilePath Convert.ToString(curPage +1);

Response.Redirect(slnk); } }

//末页

protected void lnkLast_Click(object sender, EventArgs e) {

if (iPageCount != 0) {

string slnk = Request.CurrentExecutionFilePath Convert.ToString(iPageCount);

Response.Redirect(slnk); } }

+ \"?Page=\" + \"?Page=\" + \"?Page=\" +

+

+

}

前面的序号没有填上，我这里补充下

为gridQuestion 控件DataBound 添加AddOrderId事件 protected void AddOrderId(object sender, EventArgs e) {

for (int i = 0; i < gridQuestion.Rows.Count; i++) {

//int OrderID = gridQuestion.Rows.RowIndex+1; int OrderID = curPage * iPageSize - iPageSize + 1;

gridQuestion.Rows.Cells[0].Text = (OrderID + i).ToString(); } }
