介绍asp.net的几种分页方式

通常分页有3种方法，分别是asp.net自带的数据显示空间如GridView等自带的分页，第三方分页控件如aspnetpager，存储过程分页等。这里分别做总结。
第一种：使用GridView自带分页，这种是最简单的分页方法。
前台的方法

<asp:GridView ID="GridView1" AllowPaging="true" runat="server" onpageindexchanging="GridView1_PageIndexChanging" PageSize="3"> </asp:GridView>

后台方法：

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using JXSoft.TicketManage.Model; using JXSoft.TicketManage.BLL; using System.Text.RegularExpressions; using System.Data; namespace JXSoft.TicketManage.Web { public partial class Test : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if(!IsPostBack) { BindData(); } } protected void BindData() { DataTable dt=new DataTable(); dt.Columns.Add("ID"); dt.Columns.Add("Name"); for (int i = 0; i < 10;i++ ) { dt.Rows.Add(i.ToString(), i.ToString()); } this.GridView1.DataSource = dt; this.GridView1.DataBind(); } protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) { this.GridView1.PageIndex = e.NewPageIndex; BindData(); } } }

第二种：使用个性化显示的AspNetPager.dll进行分页
此处需要添加aspnetpager.dll的引用
前台：

<form id="form1" runat="server"> <div> <asp:GridView ID="GridView1" runat="server" > </asp:GridView> <webdiyer:AspNetPager ID="AspNetPager1" runat="server" CustomInfoHTML="第%CurrentPageIndex%页，共%PageCount%页，每页%PageSize%条" FirstPageText="首页" LastPageText="尾页" LayoutType="Table" NextPageText="下一页" onpagechanging="AspNetPager1_PageChanging" PageIndexBoxType="DropDownList" PagingButtonLayoutType="Span" PrevPageText="上一页" ShowCustomInfoSection="Left" ShowPageIndexBox="Always" SubmitButtonText="Go" PageSize="4" TextAfterPageIndexBox="页" TextBeforePageIndexBox="转到"> </webdiyer:AspNetPager> </div> </form>

后台：

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using JXSoft.TicketManage.Model; using JXSoft.TicketManage.BLL; using System.Text.RegularExpressions; using System.Data; namespace JXSoft.TicketManage.Web { public partial class Test : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if(!IsPostBack) { BindData(); } } protected void BindData() { DataTable dt=new DataTable(); dt.Columns.Add("ID"); dt.Columns.Add("Name"); for (int i = 0; i < 10;i++ ) { dt.Rows.Add(i.ToString(), i.ToString()); } DataSet ds = new DataSet(); ds.Tables.Add(dt); Pager(this.GridView1, this.AspNetPager1, ds); } protected void Pager(GridView dl, Wuqi.Webdiyer.AspNetPager anp, System.Data.DataSet dst) { PagedDataSource pds = new PagedDataSource(); pds.DataSource = dst.Tables[0].DefaultView; pds.AllowPaging = true; anp.RecordCount = dst.Tables[0].DefaultView.Count; pds.CurrentPageIndex = anp.CurrentPageIndex - 1; pds.PageSize = anp.PageSize; dl.DataSource = pds; dl.DataBind(); } protected void AspNetPager1_PageChanging(object src, Wuqi.Webdiyer.PageChangingEventArgs e) { AspNetPager1.CurrentPageIndex = e.NewPageIndex; BindData(); } } }

第三种：使用AspNetPager结合存储过程进行分页
这种方法分页稍微复杂一些，但是可以应付比较大的数据量。
前台:

<asp:GridView ID="GridView1" runat="server" CssClass="GridTable" AutoGenerateColumns="false" onrowdatabound="GridView1_RowDataBound" > </asp:GridView> <webdiyer:AspNetPager ID="AspNetPager1" runat="server" CustomInfoHTML="第%CurrentPageIndex%页，共%PageCount%页，每页%PageSize%条" FirstPageT<em>本文来源[email protected]搞@^&代*@码2网</em>ext="首页" LastPageText="尾页" LayoutType="Table" NextPageText="下一页" onpagechanged="AspNetPager1_PageChanged" PageIndexBoxType="DropDownList" PagingButtonLayoutType="Span" PrevPageText="上一页" ShowCustomInfoSection="Left" ShowPageIndexBox="Always" SubmitButtonText="Go" PageSize="4" TextAfterPageIndexBox="页" TextBeforePageIndexBox="转到"> </webdiyer:AspNetPager>

后台：

//绑定方法中需要传递aspnetpager的两个属性 protected void DataBind(){ DataSet ds = reportQueryBLL.GetTcikDetailReport(this.txtStartDate.Text,this.txtEndDate.Text,int.Parse( this.DropDownListPartment1.SelectedValue), this.txtPayPerson1.Text,this.txtTicketNum.Text,this.txtTicketNo.Text, AspNetPager1.StartRecordIndex,AspNetPager1.EndRecordIndex);//注意最后两个参数是aspnetpager的属性。 this.GridView1.DataSource = ds; this.GridView1.DataBind(); } //分页控件的页索引变化事件 protected void AspNetPager1_PageChanged(object src, EventArgs e) { BindDetailReportToGv(); } //page_base中需要加载首次的数据条数 DataSet ds = reportQueryBLL.GetDetail(this.txtStartDate.Text, this.txtEndDate.Text, int.Parse(this.DropDownListPartment1.SelectedValue), this.txtPayPerson1.Text, this.txtTicketNum.Text, this.txtTicketNo.Text); this.AspNetPager1.RecordCount = ds.Tables[0].Rows.Count; BindDetailReportToGv();

这里用的存储过程比较复杂，因为SQL语句没有能够放到视图中，也无法直接从表中查出结果，这个存储过程有点变态，如果有朋友看到了，希望能指点一下。
其实存储过程的核心在于：

Create PROCEDURE [dbo].[P_GetPagedOrders2005] (@startIndex INT, @endindex INT ) AS select * from (SELECT ROW_NUMBER() OVER(ORDER BY IPid DESC) AS rownum, [IPid],[IPFrom],[IPTo],[IPLocation],[IPCity],[IPToNumber],[IPFromNumber] from IPInfo) as U WHERE rownum between @startIndex and @endIndex GO
