一个Repeater的分页方法

1.前台页面：

 

          <asp:Repeater ID="RptThankBrd" runat="server" 
               onitemdatabound="RptThankBrd_ItemDataBound">
           <ItemTemplate>
           <div class="thanktitle">
               <asp:PlaceHolder ID="PlaceHolder1" runat="server">
                          <span style="color:Blue">参调人：</span>
           <%# DataBinder.Eval( Container.DataItem,"name") %>
               </asp:PlaceHolder>
                              <asp:PlaceHolder ID="PlaceHolder2" runat="server">
                          <span style="color:Blue">流水号：</span>
           <%# DataBinder.Eval( Container.DataItem,"batchid") %>
               </asp:PlaceHolder>

           </div>
           <div class="thankcontent"><%# DataBinder.Eval( Container.DataItem,"answer") %></div>
           <div  class="pubdate">填写时间：<%# DataBinder.Eval( Container.DataItem,"insdate") %></div>
           </ItemTemplate>
           </asp:Repeater>

 

分页样式：

 

.vc
{
    padding:30px 10px 20px;
    width:90%!important;
    overflow:visible;text-align:center; font-size:15px;
    }
.vc a.o:link,.vc a.o:visited{margin:0 4px;padding:3px 6px;
    border:1px solid #ddd;text-decoration:none;
    background:#fff;}
.vc a.o:hover{border:1px solid #049;text-decoration:none;}
.vc a.obg:link,.vc a.obg:visited{background:#f00;color:#fff;}

 

 分页代码：

 

<div class="vc"> 

 <script type="text/javascript">
document.onkeyup=function(e){if(window.event.keyCode==37){window.location.href=$("#HLpre").attr("href");}}
</script>
<asp:HyperLink ID="HLpre" runat="server" style=" font-size:12px;font-weight:bold;  text-decoration:none;margin-right:15px;">&laquo;</asp:HyperLink>
第  &nbsp;   <%=pagehtml %>   &nbsp; 页&nbsp;<asp:HyperLink ID="HLnext" runat="server" style=" font-size:12px;font-weight:bold;  text-decoration:none;margin-left:15px;">&raquo;</asp:HyperLink>
<script type="text/javascript">
document.onkeydown=function(e){if(window.event.keyCode==39){window.location.href=$("#HLnext").attr("href");}}
</script>
</div>

 

后台代码：

 

 protected void Page_Load(object sender, EventArgs e)
    {
       //获取当前页码
        if (!this.IsPostBack)
        {
            if (Request.Params["page"] == null)

            else
            {
                string temp = Request.Params["page"].ToString();
                curpage = ckString.intCheck(temp, 1);
            }

        }
            
             //当前页面链接
             cururl = "viewQuestionPaper.aspx";
            //绑定数据

    }

//设置分页参数
