用aspnetpager实现datalist分页（简单使用方法）

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

<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

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();
}
