上一篇寫了一個簡單的自定義分頁控件,當時寫的不夠完善,不能自定義控件的樣式.
現在完善了,望同大家共同探討.
現在已經在網上發布的分頁控件特別多,而且大多都功能特別強,但是之所以選擇自己寫,主要是因為自己寫可
以根據自己的要求來設計,不用的功能就功能免了.
本控件可以自定義樣式,而且傳入的參數和其它常用的分頁控件差不多,記錄總數和一頁的數量,是否自定義樣式,
當頁面數量特別多的時候,可以在分頁信息欄中顯示前幾頁和后幾頁.
具體代碼如下:

控件中有默認的樣式,在分頁欄信息中,省略號前后的分頁數量都是默認值5
調用方法
前臺頁面
Code
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default5.aspx.cs" EnableViewState ="false" Inherits="Default5" %>
<%@ Register Assembly="pagerControls" Namespace="pagerControls" TagPrefix="cc1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<div>
<cc1:WebCustomControlPager iNextCount ="5" iPrevCount ="5" ID="WebCustomControlPager1" runat="server" />
</div>
</form>
</body>
</html>
后臺代碼：
Code
protected void Page_Load(object sender, EventArgs e)
{
this.WebCustomControlPager1.pageUrl = this.Request.Url.ToString();
int iPage = 1;
iPage = this.getiMatchId("page");
if (iPage < 1)
{ iPage = 1; }
this.WebCustomControlPager1.currentPageIndex = iPage;
this.WebCustomControlPager1.iNextCount = 5;
this.WebCustomControlPager1.iPrevCount = 5;
this.WebCustomControlPager1.iRowsCount = 10;
this.WebCustomControlPager1.iRecordCount = 120;
this.WebCustomControlPager1.IsCustomStyle = 1;
}
你只要在解決方案中，添加一個web控件庫，命名為pagerControls
然后把默認創建的類更名為：WebCustomControlPager
將文章的所有代碼復制過去，就可能編譯成一個控件dll
這個dll就可能加入到你的網站中了。
