本文介绍了一个ASP.NET分页控件的具体配置方法及如何通过SQL查询结合该控件实现数据分页显示。文中详细展示了分页控件的属性设置、绑定数据的方法以及分页函数的实现。

比较标准的分页显示格式和属性设置：

<webdiyer:aspnetpager
id="AspNetPager1"
runat="server"
firstpagetext="首页"
lastpagetext="尾页"
nextpagetext="下一页"
numericbuttoncount="5"
onpagechanging="AspNetPager1_PageChanging"
pagingbuttonspacing="10px"
prevpagetext="上一页"
showboxthreshold="1"
submitbuttontext="GO"
AlwaysShow="True"
ShowInputBox="Always">
</webdiyer:aspnetpager>

绑定分页数据

绑定数据表互动

/// <summary>
/// 分页控件
/// </summary>
private void BoundToAspNetPager(Wuqi.Webdiyer.AspNetPager NetPager1,int states)
{
ArrayList ParamList = new ArrayList();
string SQL1 = "SELECT * FROM ActionInfo T1 right join ZhanShang T2 on T1.ACI_ZS_ID=T2.ZS_ID right join users T3 ON T1.ACI_User_ID=T3.U_ID WHERE T1.ACI_LogicDel=1 AND ACI_ZhuangTai=@ACI_ZhuangTai";
ParamList.Add(DataParameter.MakeParam("@ACI_ZhuangTai", SqlDbType.Int, 4, states));
if (Session["UserID"] != null && Session["UserID"].ToString().Length > 0) //哪个会员申报的三名
{
SQL1 += " AND ACI_User_ID=@ACI_User_ID";
ParamList.Add(DataParameter.MakeParam("@ACI_User_ID", SqlDbType.Int, 4, int.Parse(Session["UserID"].ToString())));
}

SQL1 += " order by aci_id desc";
int Count = Pages.GetRecordCount(SQL1, ParamList);
NetPager1.PageSize = 7;
NetPager1.RecordCount = Count;

}

/// <summary>
/// 绑定到数据控件
/// </summary>
private void BoundToGridView(GridView GridViews, int states, Wuqi.Webdiyer.AspNetPager NetPager1)
{
ArrayList ParamList = new ArrayList();
string SQL1 = "SELECT * FROM ActionInfo T1 right join ZhanShang T2 on T1.ACI_ZS_ID=T2.ZS_ID right join users T3 ON T1.ACI_User_ID=T3.U_ID WHERE T1.ACI_LogicDel=1 AND ACI_ZhuangTai=@ACI_ZhuangTai";
ParamList.Add(DataParameter.MakeParam("@ACI_ZhuangTai", SqlDbType.Int, 4, states));
if (Session["UserID"] != null && Session["UserID"].ToString().Length > 0) //哪个会员申报的三名
{
SQL1 += " AND ACI_User_ID=@ACI_User_ID";
ParamList.Add(DataParameter.MakeParam("@ACI_User_ID", SqlDbType.Int, 4, int.Parse(Session["UserID"].ToString())));
}

SQL1 += " order by aci_id desc";
GridViews.DataSource = Pages.GetDataTable("ActionInfo", NetPager1.PageSize * (NetPager1.CurrentPageIndex - 1), NetPager1.PageSize, SQL1, ParamList);
GridViews.DataKeyNames = new string[] { "ACI_ID" };
GridViews.DataBind();
}

分页函数：

protected void AspNetPager1_PageChanging(object src, Wuqi.Webdiyer.PageChangingEventArgs e)
{
AspNetPager1.CurrentPageIndex = e.NewPageIndex;
BoundToAspNetPager(AspNetPager1, 0);//分页
BoundToGridView(GridView1, 0, AspNetPager1); //数据

}

有一个分页的类：

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Data.SqlClient;
using baitang.DB;
