ASP.NET中的DataList和DataRepeater提供了简单快速的方法來显示,其间，我们可以使用<ItemTemplate>更是使我们能随心所欲的控制数据的排放样式！.可惜的是它们不像Datagrid那样，有内置的分页功能。
如何解决呢？
其实我们可以【PagedDataSource】 类来解决分页的问题。
PagedDataSource类的属性：
DataSource -数据源
AllowPaging - true 是否允许分页.
PageSize - 每页项目数量
PageCount - 总页数
CurrentPageIndex - 当前所在的页索引
代码如下：
<%@ Page Language="VB" %>
<%@ import Namespace="System.Data" %>
<script runat="server">
Sub Page_Load(ByVal Sender As Object, ByVal e As EventArgs)
Dim Pgds As PagedDataSource = New PagedDataSource
Pgds.DataSource = CreateDataSource().DefaultView
Pgds.AllowPaging = True
Pgds.PageSize = 6
lblTotalPage.Text = Pgds.PageCount.ToString()
Dim CurrentPage As Integer
If Not Request.QueryString("Page") Is Nothing Then
CurrentPage = Convert.ToInt32(Request.QueryString("Page"))
Else
CurrentPage = 1
End If
Pgds.CurrentPageIndex = CurrentPage - 1
lblCurrentPage.Text = CurrentPage.ToString()
If Not Pgds.IsFirstPage Then
lnkPrev.NavigateUrl = Request.CurrentExecutionFilePath "?Page=" Convert.ToString(CurrentPage - 1)
End If
If Not Pgds.IsLastPage Then
lnkNext.NavigateUrl = Request.CurrentExecutionFilePath "?Page=" Convert.ToString(CurrentPage 1)
End If
Repeater1.DataSource = Pgds
Repeater1.DataBind()
End Sub
Function CreateDataSource() As Datatable
Dim dt As DataTable
Dim dr As DataRow
Dim i As Integer
dt = New DataTable
dt.Columns.Add(New DataColumn("IntegerValue", GetType(Integer)))
dt.Columns.Add(New DataColumn("StringValue", GetType(String)))
dt.Columns.Add(New DataColumn("DateTimeValue", GetType(DateTime)))
dt.Columns.Add(New DataColumn("BoolValue", GetType(Boolean)))
For i = 0 To 50
dr = dt.NewRow()
dr(0) = i
dr(1) = "Item " i.ToString()
dr(2) = DateTime.Now.ToShortTimeString
If (i Mod 2 <> 0) Then
dr(3) = True
Else
dr(3) = False
End If
dt.Rows.Add(dr)
Next
Return dt
End Function
</script>
