.NET基于分页控件实现真分页功能
数据绑定用Reapter控件
●把两个控件拖拽至Web窗体中(如:test.aspx)。
●AspNetPager控件的属性中可以设置每页显示记录数(如图)。
●存储过程中的代码代码如下
- set ANSI_NULLS ON
- set QUOTED_IDENTIFIER ON
- GO
- -- =============================================
- -- Author: myroom
- -- Create date: 2009-12-6
- -- Description: 新闻表的分页
- -- =============================================
- ALTER PROCEDURE [dbo].[prceNewsPagerSelectAll]
- @startIndex int,
- @endIndex int
- AS
- BEGIN
- with temptbl as(
- select ROW_NUMBER() OVER (ORDER BY id desc)AS Row,* from news
- )
- SELECT Row,title FROM temptbl where Row between @startIndex and @endIndex
- END
●执行该存储过程
- exec prceNewsPagerSelectAll 1,5
●数据访问层中
- //选出新闻表中总记录个数
- public int NewsRecordCount()
- {
- string cmdText="select * from news";
- int rc = (sqlhelper.ExecuteQuery(cmdText, CommandType.Text)).Rows .Count ;
- return rc;
- }
- //新闻表分页功能
- public DataTable SelectNewsPager(int startIndex, int endIndex)
- {
- DataTable dt = new DataTable();
- string cmdText = "prceNewsPagerSelectAll";
- SqlParameter[] paras = new SqlParameter[] {
- new SqlParameter ("@startIndex",startIndex ),
- new SqlParameter ("@endIndex",endIndex )
- };
- dt = sqlhelper.ExecuteQuery(cmdText, paras, CommandType.StoredProcedure);
- return dt;
- }
●后台代码中(test.aspx.cs)
- protected void Page_Load(object sender, EventArgs e)
- {
- if (!Page .IsPostBack )
- {
- int totalRecord = new NewsDAO().NewsRecordCount();//获取总记录数
- AspNetPager1.RecordCount = totalRecord;//对AspNetPager属性进行设置
- databind();
- }
- }
- //AspNetPager1控件的PageChanged事件
- protected void AspNetPager1_PageChanged(object sender, EventArgs e)
- {
- databind();
- }
- //数据绑定方法
- private void databind()
- {
- int startIndex = AspNetPager1.StartRecordIndex;//StartRecordIndex是AspNetPager固有属性
- int endIndex = AspNetPager1.EndRecordIndex;//EndRecordIndex是AspNetPager固有属性
- //数据绑定
- Repeater1.DataSource = new NewsDAO().SelectNewsPager(startIndex, endIndex);
- Repeater1.DataBind();
- }
●效果图如下:
●对该控件的属性进行设置还有更多效果:
