[网络收集]控件使用之——Repeater C# 分页用法

二、Web.config配置

1 <appSettings>

2 <add key="haikelasiConnectionString" value="Data Source=.;Initial Catalog=haikelasi;Persist Security Info=True;User ID=sa;Password=123456" />

3 </appSettings>

三、前台控件呈现部分

1<asp:repeater id="LeaveMessage" runat="server" >

2<ItemTemplate>

3<table width="100%" border="0" align="center" cellpadding="1" cellspacing="1" bgcolor="#D4D0C8">

4<tr>

5<td width="85%" bgcolor="#FFFAFF"><div align="left"><%#DataBinder.Eval(Container.DataItem, "sNewsTitle")%></div></td>

6<td width="15%" bgcolor="#FFFAFF" align="left"><%#DataBinder.Eval(Container.DataItem, "dAddTime")%></td>

7</tr>

8</table>

9<hr size="3px" width="90%"/>

10</ItemTemplate>

11</asp:repeater>

12共有<asp:Literal ID="RecordCount" runat="server"></asp:Literal>条记录

13共有<asp:Literal ID="PageCount" runat="server"></asp:Literal>页

14当前第<asp:Literal ID="Pageindex" runat="server"></asp:Literal>页

15<asp:HyperLink ID="FirstPage" runat="server" Text="首页"></asp:HyperLink>

16<asp:HyperLink ID="PrevPage" runat="server" Text="上一页"></asp:HyperLink>

17<asp:HyperLink ID="NextPage" runat="server" Text="下一页"></asp:HyperLink>

18<asp:HyperLink ID="LastPaeg" runat="server" Text="尾页"></asp:HyperLink>

19跳转到<asp:Literal ID="Literal1" runat="server"></asp:Literal>页
