ASP.NET（C#） Repeater分页的实现

using system.web.security;

using system.web.ui;

using system.web.ui.webcontrols;

aspx文件代码：

<table>

    <tr ><td class="style1" align ="left" >hehe</td></tr>

    <tr ><td class="style1">  

       <asp:repeater id="repeater1" runat="server" >

        <headertemplate ><table><tr><td>头模板</td></tr></headertemplate>

        <itemtemplate ><tr><td ><font color="red" > <%#("timekey")%></font></td></tr></itemtemplate>

        <alternatingitemtemplate ><tr><td > <a href ='default.aspx?id=<%#"databaselogid" %>'><%#("salesamountquota")%></a></td></tr></alternatingitemtemplate>

        <footertemplate ><tr><td>尾模板</td></tr></table></footertemplate>

        </asp:repeater>

        </td> </tr>

<tr> <td class="style1">

     <asp:hyperlink id="first" runat="server">首页</asp:hyperlink>

     <asp:hyperlink id="next" runat="server">下一页</asp:hyperlink>

     <asp:hyperlink id="up" runat="server">上一页</asp:hyperlink>

     <asp:hyperlink id="last" runat="server">末页</asp:hyperlink>

     </td></tr>

           <tr> <td class="style1">当前页为：<asp:label id="lblcurrentpage" runat="server"

                    text="label"></asp:label> 

                共<asp:label id="labpage" runat="server" text="label"></asp:label>

                页</td><td class="style1" style="height: 21px">

       <asp:hyperlink id="next" runat="server">下一页</asp:hyperlink>

第二种方式：

using system.collections;

using system.linq;

using system.xml.linq;

public partial class databind : system.web.ui.page

            num.text = "1";

            repdatabind();

    public void repdatabind()

        sqlconnection con = new sqlconnection("server='.';database=test;uid=sa;pwd=123456;");

        sqldataadapter sda = new sqldataadapter("select * from dimproduct", con);

        sda.fill(ds, "name");

        int curpage = convert.toint32(num.text);

        this.btndown.enabled = true;

        this.btnup.enabled = true;

        if (curpage == 1)

            this.btnup.enabled = false;

        if (curpage == pds.pagecount)

            this.btndown.enabled = false;

        this.repeater1.datasource = pds;

        this.repeater1.databind();

    protected void btnup_click(object sender, eventargs e)

        this.num.text =convert.tostring ( convert.toint32(num.text)- 1) ;

        repdatabind();

    protected void btndown_click(object sender, eventargs e)

        this.num.text = convert.tostring(convert.toint32(num.text)+ 1) ;
