.NET用户自定义分页控件

页面设计器内代码：

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="Pager.ascx.cs" Inherits="UserControl_Pager" %>
<table width="98%" border="0" cellpadding="0" cellspacing="0" bgcolor="#FFFFFF">
    <tr>
        <td align="right" style="padding-right: 20px; padding-top: 5px">
            <asp:HyperLink ID="hpl_First" runat="server">首页</asp:HyperLink>&nbsp;<asp:HyperLink
                ID="hpl_Prev" runat="server">上页</asp:HyperLink>&nbsp;
            <asp:HyperLink ID="hpl_Next" runat="server">下页</asp:HyperLink>&nbsp;<asp:HyperLink
                ID="hpl_Last" runat="server">末页</asp:HyperLink>
            <asp:Label ID="lb_CurrentPage" runat="server"></asp:Label>/<asp:Label ID="lbl_PageCount"
                runat="server"></asp:Label>页 共<asp:Label ID="lbl_ItemCount" runat="server"></asp:Label>条记录
            转到
            <asp:TextBox ID="txb_Page" runat="server" Width="30px" onkeyup="if(this.value.length==1){this.value=this.value.replace(/[^1-9]/g,'')}else{this.value=this.value.replace(/\D/g,'')}"
                onafterpaste="if(this.value.length==1){this.value=this.value.replace(/[^1-9]/g,'')}else{this.value=this.value.replace(/\D/g,'')}"></asp:TextBox>页&nbsp;<asp:LinkButton
                    ID="lbtn_goto" runat="server" OnClick="lbtn_goto_Click" Style="ime-mode: disabled;">转到</asp:LinkButton>
        </td>
    </tr>
</table>

后台.cs代码：

    public string url;//页面地址
    public string Params;//页面传值参数
    public int CurPage;//当前页码

    private void Page_Load(object sender, System.EventArgs e)
    {
        if (!IsPostBack)
        {
            ViewState["pageUrl"] = url;
            ViewState["pageParams"] = Params;
        }
    }


    #region 数据绑定
    /// <summary>
    /// 数据绑定
    /// </summary>
    /// <param name="dt"></param>
    /// <returns></returns>
    public PagedDataSource PagerDataBind(DataView dv)
    {
        PagedDataSource pds = new PagedDataSource();
        pds.AllowPaging = true;  //允许分页 
        pds.DataSource = dv;

        CurPage = 1;  //设置当前页的索引 
        try
        {
            if (Request.QueryString["Page"] != null)
            {
                CurPage = Convert.ToInt32(Request.QueryString["Page"].ToString());
            }
            if (CurPage < 1 || CurPage > pds.PageCount)
            {
                Response.Redirect(url + "?Page=1" + Params);
            }
        }
        catch
        {

        }
        pds.CurrentPageIndex = CurPage - 1;
        //显示状态信息 
        lbl_ItemCount.Text = pds.DataSourceCount.ToString();
        //当前页
        lb_CurrentPage.Text = CurPage.ToString();
        this.txb_Page.Text = CurPage.ToString();
        //总页数
        lbl_PageCount.Text = pds.PageCount.ToString();

        //如果当前页面不是首页 
        if (!pds.IsFirstPage)
        {

            hpl_Last.NavigateUrl = url + "?Page=" + pds.PageCount.ToString() + Params;
        }
        return pds;

}

页面调用：

<%@ Register Src="../UserControl/Pager.ascx" TagName="Pager" TagPrefix="uc" %>

html代码：

<uc:Pager ID="Pager" runat="server"></uc:Pager>

最后页面后台给分页控件赋值，调用PagerDataBind（）方法。
