Repeater控件分页例子

Repeater和DataList控件提供了一个快速、灵活的表现数据的方式，但是，它们没有内建的分页功能；DataGrid控件提供了内建的分页功能，但它的结构比较复杂。下面就用PagedDataSource类实现Repeater和DataList的分页。 PagedDataSource封装了DataGrid的分页属性，我们可以象DataGrid那样进行分页。代码如下：

<%@ Page Language="C#" %><%@ import namespace="System.Data" %><%@ import namespace="System.Data.OleDb" %><script language="C#" runat="server">public void Page_Load(Object src,EventArgs e) { OleDbConnection objConn=new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + Server.MapPath("../<a href="/dev/web/asp/" target="_blank">ASP</a>x<a href="/dev/web/" target="_blank">Web</a>.mdb")); OleDbDataAdapter objCommand=new OleDbDataAdapter("select * from Document",objConn); DataSet ds=new DataSet(); objCommand.Fill(ds); PagedDataSource objPds = new PagedDataSource(); objPds.DataSource = ds.Tables[0].DefaultView; objPds.AllowPaging = true; objPds.PageSize = 5; int CurPage; if (Request.QueryString["Page"] != null) CurPage=Convert.ToInt32(Request.QueryString["Page"]); else CurPage=1; objPds.CurrentPageIndex = CurPage-1; lblCurrentPage.Text = "当前页：" + CurPage.ToString(); if (!objPds.IsFirstPage) lnkPrev.NavigateUrl=Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage-1); if (!objPds.IsLastPage) lnkNext.NavigateUrl=Request.CurrentExecutionFilePath+ "?Page=" + Convert.ToString(CurPage+1); Repeater1.DataSource=objPds; Repeater1.DataBind();}</script><html><head><title>Repeater控件分页的例子</title><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><style> P,TD,DIV,SPAN {font-size:9pt}</style></head><body><form name="form1" method="POST" runat="server"><div style="padding:5px;background-color:#dedede"><asp:label ID="lblCurrentPage" runat="server"></asp:label></td> <td> <asp:HyperLink id="lnkPrev" runat="server">上一页</asp:HyperLink> <asp:HyperLink id="lnkNext" runat="server">下一页</asp:HyperLink> </div><hr size="1" color="#000099"/><asp:Repeater ID="Repeater1" runat="server"><Itemtemplate><div style="padding:5px;background-color:#dedede"><%# DataBinder.Eval(Container.DataItem, "Title") %></div></Itemtemplate></asp:Repeater></form></body></html>

VB.NET版本

<%@ Page Language="VB" %><%@ import namespace="System.Data" %><%@ import namespace="System.Data.OleDb" %><script language="VB" runat="server">Public Sub Page_Load(ByVal src As Object, ByVal e As EventArgs) Dim objConn As OleDbConnection = New OleDbConnection ("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + Server.MapPath("../aspxWeb.mdb")) Dim objCommand As OleDbDataAdapter = New OleDbDataAdapter ("select * from Document", objConn) Dim ds As DataSet = New DataSet () objCommand.Fill(ds) Dim objPds As PagedDataSource = New PagedDataSource () objPds.DataSource = ds.Tables(0).DefaultView objPds.AllowPaging = True objPds.PageSize = 5 Dim CurPage As Integer If Not (Request.QueryString("Page") Is Nothing) Then CurPage = Convert.ToInt32(Request.QueryString("Page")) Else CurPage = 1 End If objPds.CurrentPageIndex = CurPage - 1 lblCurrentPage.Text = "当前页：" + CurPage.ToString() If Not objPds.IsFirstPage Then lnkPrev.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage - 1) End If If Not objPds.IsLastPage Then lnkNext.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage + 1) End If Repeater1.DataSource = objPds Repeater1.DataBind() End Sub</script><html><head><title>Repeater控件分页的例子</title><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><style> P,TD,DIV,SPAN {font-size:9pt}</style></head><body><form name="form1" method="POST" runat="server"><div style="padding:5px;background-color:#dedede"><asp:label ID="lblCurrentPage" runat="server"></asp:label></td> <td> <asp:HyperLink id="lnkPrev" runat="server">上一页</asp:HyperLink> <asp:HyperLink id="lnkNext" runat="server">下一页</asp:HyperLink> </div><hr size="1" color="#000099"/><asp:Repeater ID="Repeater1" runat="server"><Itemtemplate><div style="padding:5px;background-color:#dedede"><%# DataBinder.Eval(Container.DataItem, "Title") %></div></Itemtemplate></asp:Repeater></form></body></html>
