这里有新鲜出炉的精品教程,程序狗速度看过来!

ASP.NET

ASP.NET 是.NET FrameWork的一部分,是一项微软公司的技术,是一种使嵌入网页中的脚本可由因特网服务器执行的服务器端脚本技术,它可以在通过HTTP请求文档时再在Web服务器上动态创建它们。 指 Active Server Pages(动态服务器页面) ,运行于 IIS(Internet Information Server 服务,是Windows开发的Web服务器)之中的程序 。


这篇文章主要介绍了asp.net自定义分页控件示例,大家参考使用吧

一、.ascx页面


<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Pagination.ascx.cs" Inherits="IOCS.WEB.UserControl.Pagination" %>
<link href="../Content/Css/Pager.css" rel="stylesheet" type="text/css" />
<div id="tbPage" class="pager" runat="server" >
    記錄總數:<asp:Label ID="LRecords" runat="server"></asp:Label>
    總頁數:<asp:Label ID="LPages" runat="server"></asp:Label>
    當前頁:<asp:Label ID="LPage" runat="server"></asp:Label>

        <asp:LinkButton ID="LinkFirst" runat="server" CommandArgument="first" nClick="PagerButtonClick"
            Text="首頁"></asp:LinkButton>

        <asp:LinkButton ID="LinkPrevious" runat="server" CommandArgument="prev" nClick="PagerButtonClick"
            Text="上一頁"></asp:LinkButton>

        <asp:LinkButton ID="LinkNext" runat="server" CommandArgument="next" nClick="PagerButtonClick"
            Text="下一頁"></asp:LinkButton>

        <asp:LinkButton ID="LinkLast" runat="server" CommandArgument="last" nClick="PagerButtonClick"
            Text="末頁"></asp:LinkButton>
    轉到第<asp:TextBox ID="txtpage"  CssClass="piut" runat="server"  MaxLength="5" AutoPostBack="True" nTextChanged="txtpage_TextChanged"></asp:TextBox>頁

二、.ascx.cs文件


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace IOCS.WEB.UserControl
{
    public partial class Pagination : System.Web.UI.UserControl
    {
        public event EventHandler PageButtonClick;
        public bool FirstPost = false;
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
              

            }
            // 只輸入數字
            txtpage.Attributes.Add("onclick",
                @"if(!((event.keyCode>=48&&event.keyCode<=57)
                    ||(event.keyCode>=96&&event.keyCode<=105)
                    ||(event.keyCode==8)))event.returnValue=false;"
              );

        }
        GridView _gv;

        /// <summary>
        /// 需要分頁的GridView
        /// </summary>
        public GridView TargetControlID
        {

            get
            {
                return _gv;
            }
        }

        protected void PagerButtonClick(object sender, EventArgs e)
        {
            //獲得linkebutton的參數值
            string arg = ((LinkButton)sender).CommandArgument;
            switch (arg)
            {
                case ("next"):
                    {
                        if (_gv.PageIndex < _gv.PageCount - 1)
                        {
                            _gv.PageIndex=_gv.PageIndex+1;
                        }
                        break;
                    }
                case ("prev"):
                    {
                        if (_gv.PageIndex > 0)
                        {

                    }

                default:
