如何使用PagedDataSource做DataRepeater的分的效果_.NET教程

ASP.NET中的DataList和DataRepeater提供了快速的方法展料,
其<ItemTemplate>更是我能心所欲的定料的排放方式.可惜的是他
不像Datagrid那,有建的分功能.

如何解不能分的呢?在篇文章中介如何使用 PagedDataSource Class 解分的.

的介常用到的 PagedDataSource Class Public Properties

DataSource - 料源
AllowPaging - true 允分;false 不允.
PageSize - 定重多少次
PageCount - 共有
CurrentPageIndex - 目前所在的
IsFirstPage - 是第一,回True or False
IsLastPage - 是最後一,回True or False

下面就是例(剪就可以直接跑了)

--------------------------------------------------------------------------------

<%@ Page Language="VB" %>
<%@ import Namespace="System.Data" %>
<script runat="server">
Sub Page_Load(Sender As Object, E As EventArgs)

Dim Pgds As PagedDataSource = New PagedDataSource()
Pgds.DataSource = CreateDataSource().DefaultView
Pgds.AllowPaging = True
Pgds.PageSize = 6 '定重多少次
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 = "Page: " + 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

'This part is an example from Asp.net QuickStart
'You can change this part with your own Dataset

Dim dt As DataTable
Dim dr As DataRow
Dim i As Integer

'create a DataTable
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)))

'Make some rows and put some sample data in
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
'add the row to the datatable
dt.Rows.Add(dr)
Next

Return dt

End Function
