ASP.NET自訂分頁程式碼

一、自訂分頁類 PagerHelper

代碼如下

複製代碼

public class PagerHelper     { private int _pageSize = 10; /// <summary> /// 每頁預設10條數 /// </summary> public int pageSize {     get     { if (_pageSize < 1)     _pageSize = 1; return _pageSize;     }     set { _pageSize = value; } } private int _extendPage = 5; /// <summary> /// 每頁顯示分頁數 /// </summary> public int extendPage {     get     { if (_extendPage < 3)     _extendPage = 3; return _extendPage;     }     set     { _extendPage = value;     } } private int _currentPage = 1; /// <summary> /// 當前頁碼 /// </summary> public int currentPage {     get     { if (_currentPage < 1)     _currentPage = 1; if (_currentPage > totalPages)     _currentPage = totalPages;

} else {     _startPage = endPage - extendPage + 1; }     }     else     { _startPage = 1;     } } else {     _startPage = 1; } return _startPage;     } } /// <summary> /// 擷取最後一個顯示的頁面 /// </summary> private int endPage {     get     { int _endPage = 0;

}     }     else     { _endPage = extendPage;     } } else {     _endPage = totalPages; } return _endPage;     } } private string _HtmlDisablePrevPage = ""; /// <summary> /// 第一頁時上一頁的樣式 /// </summary> public string HtmlDisablePrevPage {     get { return _HtmlDisablePrevPage;

} else {     if (pageUrl.IndexOf("?") > 0) strReturnHtml += "<script>function GoToPage(pg){if(isNaN(pg)||pg>" + totalPages + "||pg<1){window.alert('請正確輸入頁碼,只能為正整數!且不能大於" + totalPages + "');return false;}else{window.location.href='" + pageUrl + "&pn='+pg+'';return true;}}</script>";     else strReturnHtml += "<script>function GoToPage(pg){if(isNaN(pg)||pg>" + totalPages + "||pg<1){window.alert('請正確輸入頁碼,只能為正整數!且不能大於" + totalPages + "');return false;}else{window.location.href='" + pageUrl + "?pn='+pg+'';return true;}}</script>"; } return strReturnHtml;     }     set     { _HTMLMoveToPage = value;     } } private string _HtmlPrevPage = @""; /// <summary> /// 上一頁代碼 /// </summary> public string HtmlPrevPage {     get     { if (isRewrite) {     if (currentPage < 2 )     {  return _HtmlDisablePrevPage;     }     else     { return string.Format(_HtmlPrevPage, string.Format(pageUrl, 1), string.Format(pageUrl, prevPage));     } } else {     if (currentPage < 2)     { return _HtmlDisablePrevPage;     }     else     { if (pageUrl.IndexOf("?") > 0)     return string.Format(_HtmlPrevPage, pageUrl + "&pn=1", pageUrl + string.Format("&pn={0}", prevPage)); else     return string.Format(_HtmlPrevPage, pageUrl + "?pn=1", pageUrl + string.Format("?pn={0}", prevPage));     } }     }     set     { _HtmlPrevPage = value;     } } private string _HtmlNextPage = @""; /// <summary> /// 下一頁html代碼 /// </summary> public string HtmlNextPage {     get     { if (isRewrite) {     if (currentPage < totalPages)     { return string.Format(_HtmlNextPage, string.Format(pageUrl, nextPage), string.Format(pageUrl, totalPages));     }     else     { return _HtmlDisableNextPage;     } } else {     if (currentPage < totalPages)     { if (pageUrl.IndexOf("?") > 0)     return string.Format(_HtmlNextPage, pageUrl + string.Format("&pn={0}", nextPage), pageUrl + string.Format("&pn={0}", totalPages)); else     return string.Format(_HtmlNextPage, pageUrl + string.Format("?pn={0}", nextPage), pageUrl + string.Format("?pn={0}", totalPages));     }     else     { return _HtmlDisableNextPage;     } }     }     set     { _HtmlNextPage = value;     } } private string _HtmlCurrentPage = @"<span style=""color:Red"">{0}</span>&nbsp;"; /// <summary> /// 當前頁html代碼 /// </summary> public string HtmlCurrentPage {     get { return _HtmlCurrentPage; }     set { _HtmlCurrentPage = value; } } private string _HtmlPageNum = ""; /// <summary> /// 頁碼數的html /// </summary> public string HtmlPageNum {     get { return _HtmlPageNum; }     set { _HtmlPageNum = value; } } private string _HtmlPageTag = @"<div class=""page""><ul>{0}</ul></div>"; /// <summary> /// 用於設定分頁html外面的div, span等標 /// </summary> public string HtmlPageTag {     get { return _HtmlPageTag; }     set { _HtmlPageTag = value; } } /// <summary> /// 擷取最終html /// </summary> /// <returns></returns> public string GetHtmlPage() {    return GetHtmlPage(false); } /// <summary> /// 擷取最終html /// </summary> /// <returns></returns> public string GetHtmlPage(bool bGoToPage) {     if (totalPages <= 0) return "";     StringBuilder s = new StringBuilder("");     s.Append(HtmlPrevPage);     for (int i = startPage; i <= endPage; i++)     { if (i == currentPage) {     s.Append(string.Format(HtmlCurrentPage, i)); } else {     if (isRewrite)     { s.Append(string.Format(HtmlPageNum, string.Format(pageUrl, i), i));     }     else     { if (pageUrl.IndexOf("?") > 0)     s.Append(string.Format(HtmlPageNum, string.Format(pageUrl + @"&pn={0}", i), i)); else     s.Append(string.Format(HtmlPageNum, string.Format(pageUrl + @"?pn={0}", i), i));     } }     }     s.Append(HtmlNextPage);     if (bGoToPage)     { s.Append(HTMLMoveToPage);     }     return string.Format(HtmlPageTag, s.ToString()); } /// <summary> /// 擷取最終html /// </summary> /// <returns></returns> public string GetHtmlNoNumsPage() {     if (totalPages < 0) return "";     StringBuilder s = new StringBuilder("");     if (bHtmlCurOfTotalPage)     { if (string.IsNullOrEmpty(HtmlCurOfTotalPage))     s.Append(string.Format(" 第 {0}/{1} 頁 ", currentPage, totalPages)); else     s.Append(string.Format(HtmlCurOfTotalPage, currentPage, totalPages));     }     s.Append(HtmlPrevPage);     s.Append(HtmlNextPage);     return string.Format(HtmlPageTag, s.ToString()); }     }

二、使用執行個體
 

代碼如下

複製代碼

public string GetHtmlPager() {     PagerHelper pHelper = new PagerHelper();     pHelper.HtmlPageTag = @"<div class=""fenye""><ul>{0}</ul></div>";     pHelper.pageUrl = url;     pHelper.totalRows = TotalCount;     pHelper.pageSize = pageSize;     pHelper.extendPage = 8;     pHelper.HtmlPrevPage = @"<li><a href=""{1}"">上一頁</a></li>";     pHelper.HtmlNextPage = @"<li><a href=""{0}"">下一頁</a></li>";     pHelper.HtmlDisablePrevPage = @"<li><span class=""nohref"">上一頁</span></li>";     pHelper.HtmlDisableNextPage = @"<li><span class=""nohref"">下一頁</span></li>";     pHelper.HtmlCurrentPage = @"<li class=""current"">{0}</li> ";     pHelper.currentPage = pageIndex;     pHelper.HtmlPageNum = @"<li><a href=""{0}"">{1}</a></li> ";     return pHelper.GetHtmlPage(); }

自訂分頁控制項

使用：

代碼如下	複製代碼
<%@ Register assembly="YSM.AspNetPager" namespace="YSM.AspNetPager" tagprefix="cc1" %>

頁面註冊控制項，也可以在web.config中配置
1.ajax之UpdatePanel分頁則把控制項放到UpdatePanel裡面即可（不能啟用url重寫和url參數分頁，即跳轉頁面）

代碼如下	複製代碼
<cc1:YsmPager ID="YsmPager1" runat="server" PageSize="10" onpagechanged="YsmPager1_PageChanged" CssClass="yahoo" CurrentPageButtonClass="current" DisabledButtonClass="disabled"></cc1:YsmPager>

CssClass：設定控制項div的樣式；CurrentPageButtonClass：設定當前索引頁的樣式；DisabledButtonClass：設定啟用上一頁下一頁按鈕時的禁用樣式。
2.url重寫分頁需要設定UrlRewriting屬性為true，Url重寫規則UrlRewritePattern屬性。

代碼如下	複製代碼
<cc1:YsmPager ID="YsmPager2" runat="server" PageSize="10" UrlRewriting="true" UrlRewritePattern="index-{0}-[cid].html"></cc1:YsmPager>

index-{0}-[cid].html多個參數時候的使用頁面使用{0}自動格式化,其他參數使用[你的參數名]進行配置。
屬性介紹：
PageSize：擷取或設定每頁顯示記錄數
CurrentPageIndex：擷取或設定當前頁索引
RecordCount：擷取或設定記錄總數（必須設定值才能產生分頁連結）
PageCount：擷取頁總數，此屬性只有get
UrlPaging：是否啟用Url傳參方式分頁（預設false）
UrlPageIndexName："擷取或設定當啟用Url分頁方式時，在url中表示要傳遞的頁索引的參數的名稱（預設page）。
UrlRewriting：是否啟用Url重寫，當為true時UrlPaging自定為true（預設false）
UrlRewritePattern：Url重寫格式（預設null）
CurrentPageButtonClass:當前頁按鈕樣式（預設null）
DisabledButtonClass:設定禁用上一頁下一頁按鈕樣式（預設null）
FirstPageText：設定第一頁按鈕的文本（預設1）
LastPageText:設定最後一夜按鈕的文本（預設PageCount的值）
ShowJumpBox:設定是否顯示跳轉框（預設顯示）
