用aspnetpager实现datalist分页

aspnetpager对datalist分页的使用，网上关于datalist分页的办法很多，但是我觉得都不是很简单实用，有的是url提交，有的是存储过程分页，不方便。下面就是aspnetpager的分页，代码。

1.首先下载aspnetpager控件，http://www.webdiyer.com/download/default.aspx。

2.在工具箱里面添加aspnetpager控件。

3.前台引用

[html] view plaincopy

<asp:DataList runat="server" ID="dlPicList" Width="100%" Border="0" CellSpacing="0" CellPadding="0" RepeatColumns="4" RepeatDirection="Horizontal">

<ItemTemplate>

<a href='<%# "PicView.aspx?PicID="+Eval("PicID")%>'><asp:Image ID="imPic" runat="server" ImageUrl='<%# Bind("PicUrl")%>' width="104" height="76" BorderWidth="1" /><br />

<asp:Label runat="server" ID="lblTitle" Text='<%# Bind("DisTitle")%>'></asp:Label></a>

</ItemTemplate>

<ItemStyle CssClass="word_green" HorizontalAlign="Center" />

</asp:DataList>

<webdiyer:AspNetPager ID="AspNetPager1" runat="server" PageSize="5" ShowBoxThreshold="1" AlwaysShow="True" FirstPageText="首页" LastPageText="末页"

NextPageText="下一页" PrevPageText="上一页" onpagechanging="AspNetPager1_PageChanging">

</webdiyer:AspNetPager>

4.后台代码

[csharp] view plaincopy

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

BindData();

}

}

private void BindData()

{

conn = ConfigurationManager.ConnectionStrings["STRING_SqlConn"].ToString();

object[] para = { 0, picid };

DataTable dt = DataOperator.TableUseTrans(conn, "SP_Pic_GetView", para);

DataView dv = dt.DefaultView;

//对用于分页的类的引用

PagedDataSource pds = new PagedDataSource();

pds.DataSource = dv;//设置数据源(DataTable类型)

pds.AllowPaging = true;

//每页显示的行数

//pds.PageSize = 12;

AspNetPager1.RecordCount = dv.Count;

pds.CurrentPageIndex = AspNetPager1.CurrentPageIndex - 1;

pds.PageSize = AspNetPager1.PageSize;

dlPicList.DataSource= pds;

dlPicList.DataBind();

}

protected void AspNetPager1_PageChanging(object src, Wuqi.Webdiyer.PageChangingEventArgs e)

{

AspNetPager1.CurrentPageIndex = e.NewPageIndex;

BindData();

}
