ASP.NET（C#） Repeater分页的实现
第一种方式：
数据库连接代码：
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;
using System.Data.Sql;
public partial class _Default : System.Web.UI.Page
{
private void con()
{
SqlConnection con = new SqlConnection("server='.';database=test;uid=sa;pwd=123456;");
SqlConnection conn = new SqlConnection();
DataSet ds = new DataSet();
SqlDataAdapter sda = new SqlDataAdapter("select * from news", con);
sda.Fill(ds, "newsTitle");
//SqlDataAdapter sda2 = new SqlDataAdapter("select * from ProspectiveBuyer", con);
// sda2.Fill(ds, "title");
PagedDataSource pds = new PagedDataSource();
pds.DataSource = ds.Tables["name"].DefaultView;
//PagedDataSource aa = new PagedDataSource();
pds.AllowPaging = true;//允许分页
pds.PageSize = 8;//单页显示项数
int CurPage;
if (Request.QueryString["Page"] != null)
CurPage = Convert.ToInt32(Request.QueryString["Page"]);
else
CurPage = 1;
pds.CurrentPageIndex = CurPage - 1;
int Count = pds.PageCount;
lblCurrentPage.Text = "当前页：" + CurPage.ToString();
labPage.Text = Count.ToString();
if (!pds.IsFirstPage)
{
this.first.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=1";
this.last.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(Count - 1); ;
up.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage - 1);
}
else
{
this.first.Visible = false ;
this.last.Visible = false ;
}
if (!pds.IsLastPage)
{
next.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage + 1);
}
else
{
this.first.Visible = false;
this.last.Visible = false;
}
Repeater1.DataSource = pds ;
Repeater1.DataBind();
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
con();
this.first.Visible = true;
this.last.Visible = true;
//this.Repeater1.DataSource = pds();
//this.Repeater1.DataBind();
}
}
}
