ASP如何制作用户自定义控件

1.打开VS2008-新建一个工程-选译ASP。

NET服务器控件2.自动生成一个文件，打代码拷进去,调试好程序3.点击“生成菜单-生成XX”4.到工程目录\bin\Debug 找到dll文件把它拷到一个固定目录里如:DotNet_DLL里============附带一个我重写Repeater的代码=================== using System;using System.Collections.Generic;using ponentModel;using System.Linq;using System.Text;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using System.Data;using System.Data.SqlClient;using System.Data.OleDb;namespace lwf_MVC.lwf_Controls{[DefaultProperty("pageIndex")][ToolboxData("<!--Repeater Begin --><{0}:Repeater ID=\"Rep_list\" runat=\"server\" EnableViewState=\"false\"DisplayPageing=\"Always\"><ItemTemplate></ItemTemplate></{0}:Repeater> <!--Repeater End -->")]public class Repeater : System.Web.UI.WebControls.Repeater{private int _recordcount = 0;private int _pageSize = 0;private int _pageIndex = 1;private string _PID = "";private string _CssClass = "CssPage"; //输出数据流时设一个样式给它样式名为CssPageprivate object _DataSourceList;private PagedDataSource _pds = new PagedDataSource();//public bool _DisplayPageing;public MyEnum _DisplayPageing;private MyEnumLanguage _Language;//构造函数public Repeater(){}#region ____________控件属性:RecordCount、pageSize、pageIndex、PID、CssClass、DataSource1____________[Bindable(true)][Category("data")][DefaultValue("1")][Localizable(true)][Description("记录总数")]public int RecordCount{get{return _recordcount;}set{_recordcount = value;}}[Bindable(true)][Category("data")][DefaultValue("15")][Localizable(true)][Description("单页记录数")]public int pageSize{get{return _pageSize;}set{_pageSize = value;}}[Bindable(true)][Category("data")][DefaultValue("1")][Localizable(true)][Description("当前页码")]public int pageIndex{get{return _pageIndex;}set{_pageIndex = value;}}[Bindable(true)][Category("data")][DefaultValue("")][Localizable(true)][Description("其它参数传递")]public string PID{get{return _PID;}set{_PID = value;}}[Bindable(true)][Category("data")][DefaultValue("CssPage")][Localizable(true)][Description("连接样式")]public string CssClass{get{return _CssClass;}set{_CssClass = value;}}[Bindable(true)][Category("data")][DefaultValue("")][Localizable(true)][Description("数据源,DataTable")]public object DataSource1{get{return _pds;}set{switch (value.GetType().ToString()){case "System.Data.DataTable":_recordcount = ((DataTable)value).Rows.Count;_pds.DataSource = ((DataTable)value).DefaultView;break;case"System.Collections.Generic.List`1[System.Object]":_recordcount = ((List<object>)value).Count;_pds.DataSource = (List<object>)value;break;case"System.Data.SqlClient.SqlDataReader":DataTable i_dt = Normal.ConvertDataReaderToDataTable((SqlDataReader)value);_recordcount =i_dt.Rows.Count;_pds.DataSource =i_dt.DefaultView;break;case"System.Data.SqlClient.OleDbDataReader":DataTable i_dtOle = Normal.ConvertDataReaderToDataTable((OleDbDataReader)value);_recordcount =i_dtOle.Rows.Count;_pds.DataSource =i_dtOle.DefaultView;break;default:_recordcount = ((DataTable)value).Rows.Count;_pds.DataSource = ((DataTable)value).DefaultView;break;}_pds.AllowPaging = true;_pds.PageSize = _pageSize;_pds.CurrentPageIndex = this._pageIndex - 1;base.DataSource = _pds;}}public MyEnum DisplayPageing{get { return _DisplayPageing; }set { _DisplayPageing = value; }}public enum MyEnum{Always = 1,Auto = 2,Never = 3}public MyEnumLanguage Language{get { return _Language; }set { _Language = value; }}public enum MyEnumLanguage{Chinese = 1,English = 2}#endregion//外部使用public string ThePage(){string retStr = "";retStr = this.ThePage(_recordcount, _pageSize,_pageIndex, _PID, _CssClass);return retStr;}//分页函数，为输出显示流提供HTML代码/// <summary>/// 分页函数/// </summary>/// <param name="i_RecordCount">总记录数</param>/// <param name="i_pageSize">每页记录数</param>/// <param name="i_pageIndex">当前页数</param>/// <param name="i_PID">其它参数</param>/// <param name="i_CssClass">连接样式</param>/// <returns>HTML代码</returns>public string ThePage(int i_RecordCount, int i_pagesize, int i_pageIndex, string i_PID, string i_CssClass){int i_Pcount = 0;int i_StartPageNum;int i_EndPageNum;string i_pagerString = "";string i_pagerString_ENG = "";i_pagerString = i_pagerString + "<styletype=\"text/css\">\n.CssPage {font-family: Arial, Helvetica, sans-serif;font-size: 12px;line-height: 25px;color: #333;text-decoration:none;}\na.CssPage:hover{font-family: Arial, Helvetica, sans-serif;font-size:12px;line-height: 25px;color: #ff0000;text-decoration: underline;}\n</style>\n";i_pagerString_ENG = i_pagerString_ENG + "<style type=\"text/css\">\n.CssPage {font-family: Arial, Helvetica, sans-serif;font-size: 12px;line-height: 25px;color: #333;text-decoration:none;}\na.CssPage:hover{font-family: Arial, Helvetica, sans-serif;font-size:12px;line-height: 25px;color: #ff0000;text-decoration: underline;}\n</style>\n";if (i_pagesize != 0){i_Pcount = (i_RecordCount / i_pagesize);i_Pcount = ((i_RecordCount %i_pagesize) != 0 ?
