DataList和DataRepeater分页

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 DataTableDim dr As DataRowDim 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 50dr = dt.NewRow()dr(0) = idr(1) = "Item " + i.ToString()dr(2) = DateTime.Now.ToShortTimeStringIf (i Mod 2 <> 0) Thendr(3) = TrueElsedr(3) = FalseEnd If

dt.Rows.Add(dr)Next

Return dt

End Function
