Repeater控件实现分页代码

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_r(Container.DataItem,  " sNewsTitle " ) %> </ div ></ td >
 6   < td  width ="15%"  bgcolor ="#FFFAFF"  align ="left" > <% #DataBinder.eval_r(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
