.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" %>

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

cs代码中：

 1 DataTable dt = new DataTable();
 2 PagedDataSource pds = new PagedDataSource();
 3 
 4 protected void Page_Load(object sender, EventArgs e)
 5     {
 6             dt = .......;
 7             pds.DataSource = dt.DefaultView;
 8             pds.AllowPaging = true;
 9             pds.PageSize = 10;
10             AspNetPager1.RecordCount = pds.Count;
11             AspNetPager1.PageSize = pds.PageSize;
12             if (!IsPostBack)
13             {
14                 Repeater1.DataSource = pds;
15                 Repeater1.DataBind();
16             }
17         }
18     }
19 
20     protected void AspNetPager1_PageChanged(object sender, EventArgs e)
21     {
22         pds.CurrentPageIndex = AspNetPager1.CurrentPageIndex - 1;//索引同步
23         Repeater1.DataSource = pds;//数据绑定
24         Repeater1.DataBind();
25     }

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();
    }
