[ASP.NET2.0]Repeater C# 分页用法

 转自：http://www.cnblogs.com/xiediy/archive/2008/09/09/1287567.html

 

一、预览效果

 

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
