.net分页控件webdiyer:AspNetPager

首先下载：AspNetPager.dll AspNetPager.xml 放到bin目录下
页面添加<%@ Register Assembly="AspNetPager" Namespace="Wuqi.Webdiyer" TagPrefix="webdiyer" %>

<webdiyer:AspNetPager ID="AspNetPager1" runat="server" OnPageChanged="AspNetPager1_PageChanged"
FirstPageText="首页" LastPageText="尾页" NextPageText="下一页" PrevPageText="上一页" ShowPageIndexBox="Never"
AlwaysShow="true" UrlPaging="True" ReverseUrlPageIndex="True">
</webdiyer:AspNetPager>

cs代码中：

DataTable dt = new DataTable();
PagedDataSource pds = new PagedDataSource();

protected void Page_Load(object sender, EventArgs e)
{
dt = .......;
pds.DataSource = dt.DefaultView;
pds.AllowPaging = true;
pds.PageSize = 10;
AspNetPager1.RecordCount = pds.Count;
AspNetPager1.PageSize = pds.PageSize;
if (!IsPostBack)
{
Repeater1.DataSource = pds;
Repeater1.DataBind();
}
}
}

protected void AspNetPager1_PageChanged(object sender, EventArgs e)
{
pds.CurrentPageIndex = AspNetPager1.CurrentPageIndex - 1;//索引同步
Repeater1.DataSource = pds;//数据绑定
Repeater1.DataBind();
}

这样分页显示没问题了，但要是页面中有检索条件，需要重新给datatable赋值的话，点翻页就会出问题了。比如检索出的数据有5页，而page_load中加载的datatable有10页。

点击检索按钮检索出需要的数据后，再翻页又变成全部数据了。下边解决。

DataTable dt = new DataTable();
PagedDataSource pds = new PagedDataSource();
static DataView view = new DataView();
protected void Page_Load(object sender, EventArgs e)
{
dt = .....;
if (Request.QueryString["page"] == null)
{
view = dt.DefaultView;
}
if (!IsPostBack)
{
pds.DataSource = view;
AspNetPager1.RecordCount = view.Count;
pds.AllowPaging = true;
pds.PageSize = 5;
AspNetPager1.PageSize = pds.PageSize;
Repeater1.DataSource = pds;
Repeater1.DataBind();
}
}
protected void AspNetPager1_PageChanged(object sender, EventArgs e)
{
pds.CurrentPageIndex = AspNetPager1.CurrentPageIndex - 1;//索引同步
Repeater1.DataSource = pds;//数据绑定
Repeater1.DataBind();
}
//按条件检索
protected void Button1_Click(object sender, EventArgs e)
{
//button1  根据订单编号和订单时间搜索
string ddh = TextBox1.Text.Replace(" ", "");
string startDt = TxtStartTime.Value;
string endDt = TxtEndTime.Value;
dt = 新table;
view = dt.DefaultView;
pds.DataSource = view;
AspNetPager1.RecordCount = view.Count;
pds.AllowPaging = true;
pds.PageSize = 5;
AspNetPager1.PageSize = pds.PageSize;
Repeater1.DataSource = pds;
Repeater1.DataBind();
}
