今天完成的自定义分页控件，支持AJAX.DLL的方式支持24种分页样式

分页控件，大家应该都比较熟悉了。但是一直以来分页控件都给我一个很郁闷的地方，几乎都是URL传值，让人很郁闷。

如果我的是高级查询，里面的值有很多，那写死个人。同时对系统的请求也是一个考验。于是我写了这个分页控件。同时支持24种分页样式。

代码如下：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Web.UI;using System.Web.UI.WebControls;using System.ComponentModel;using System.Web.UI.HtmlControls;namespace MyControl{    [DefaultProperty("Text")]    [ToolboxData("<{0}:DataPager runat=server></{0}:DataPager>")]    public class DataPager : WebControl, INamingContainer, IPostBackEventHandler    {        public event EventHandler PagerOnclick        {            add            {                Events.AddHandler(this, value);            }            remove            {                Events.RemoveHandler(this, value);            }        }        protected void _PagerClick(object sender, EventArgs e)        {            EventHandler hd = (EventHandler)base.Events[this];            if (hd != null)            {                hd(sender, e);            }        }        public void RaisePostBackEvent(string Index)        {            //Label lbl = (Label)this.FindControl("lbl");            //lbl.Text += "自己的事件:" + Index;        }        void btn_Click(object sender, EventArgs e)        {            try            {                int pageIndex = int.Parse(((sender) as LinkButton).Text);                this.PageIndex = pageIndex;                _PagerClick(sender, e);            }            catch (Exception) { }        }        /// <summary>        /// 当前页数        /// </summary>        public int PageIndex        {            get { return int.Parse(ViewState["PageIndex"] == null ?

你可以选择手动或者自动输入样式，当两个样式都有的时候使用手动设置的样式。

同时，点击页数的事件 直接赋值 或者点击写都可以

前台调用代码如下：

  <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">             <ContentTemplate>                <cc1:DataPager ID="DataPager2" runat="server"  SelectDisplayStyle="flickr"  OnPagerOnclick="DataPager1_PagerOnclick1" />                  <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>            </ContentTemplate>      </asp:UpdatePanel>

CS代码：

    protected void Page_Load(object sender, EventArgs e)    {        if(!IsPostBack)        {            //this.PagingBar1 = new MyControl.PagingBar();            this.DataPager1.PageIndex = 5;            this.DataPager1.PageSize = 20;            this.DataPager1.TotalPage = 30;            this.DataPager1.TotalRecord = 500;            this.DataPager2.PageIndex = 5;            this.DataPager2.PageSize = 20;            this.DataPager2.TotalPage = 30;            this.DataPager2.TotalRecord = 500;            //this.DataPager1.        }    }      protected void DataPager1_PagerOnclick1(object sender, EventArgs e)    {        //int PageIndex = this.DataPager1.PageIndex;        int strthisPage = DataPager2.PageIndex;   //Convert.ToInt32(((sender) as LinkButton).Text);       // this.DataPager1.PageIndex = strthisPage;        Label1.Text = strthisPage.ToString();    }

对了，24种样式的命名我改了下。有几个样式带横线，我把横线去掉了。
