分页详解,ASP.NET书本 “数据空间应用”
(1)使用GridView控件分页显示 步奏:1.添加GridView控件 2.将GrideView控件的AllowPaging属性设置为True,表示允许分页 3.将PageSize属性设置一个数字,用来控制每页中显示的记录数 4.最后在GridView控件的PageIndexChanging事件中设置GridView控件的PageIndex属性为当前页的索引值,并重新绑定GridView控件
(2)DataList控件中的数据
using System; using System.Configuration; using System.Data; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq; using System.Data.SqlClient; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { Bind();//数据绑定 } } //进行数据绑定的方法 public void Bind() { int CurrentPage = Convert.ToInt32(labNowPage.Text); ///labNowPage标签 记录当前页码 PagedDataSource ps = new PagedDataSource();//生成PagedDataSource的实例 //实例化SqlConnection对象 SqlConnection sqlCon = new SqlConnection(); //实例化SqlConnection对象连接数据库的字符串 sqlCon.ConnectionString = "server=.;uid=sa;pwd=;database=db_09"; //定义SQL语句 string SqlStr = "select * from tb_Student"; //实例化SqlDataAdapter对象 SqlDataAdapter da = new SqlDataAdapter(SqlStr, sqlCon); //实例化数据集DataSet DataSet ds = new DataSet(); da.Fill(ds, "tb_Student"); ps.DataSource = ds.Tables["tb_Student"].DefaultView; ps.AllowPaging = true; //是否可以分页 ps.PageSize = 2; //显示的数量 ps.CurrentPageIndex = CurrentPage - 1; //取得当前页的页码 lnkbtnFront.Enabled = true; lnkbtnFirst.Enabled = true; lnkbtnNext.Enabled = true; lnkbtnLast.Enabled = true; if (CurrentPage == 1) { lnkbtnFirst.Enabled = false;//不显示第一页按钮 lnkbtnFront.Enabled = false;//不显示上一页按钮 } if (CurrentPage == ps.PageCount) { lnkbtnNext.Enabled = false;//不显示下一页 lnkbtnLast.Enabled = false;//不显示最后一页 } this.labCount.Text = Convert.ToString(ps.PageCount);//记录总页数 this.DataList1.DataSource = ps; this.DataList1.DataKeyField = "ID"; this.DataList1.DataBind(); } //首页 protected void lnkbtnFirst_Click(object sender, EventArgs e) { this.labNowPage.Text = "1"; this.Bind(); } //上一页 protected void lnkbtnFront_Click(object sender, EventArgs e) { this.labNowPage.Text = Convert.ToString(Convert.ToInt32(this.labNowPage.Text) - 1); this.Bind(); } //下一页 protected void lnkbtnNext_Click(object sender, EventArgs e) { this.labNowPage.Text = Convert.ToString(Convert.ToInt32(this.labNowPage.Text) + 1); this.Bind(); } //尾页 protected void lnkbtnLast_Click(object sender, EventArgs e) { this.labNowPage.Text = this.labCount.Text; this.Bind(); } }
