Repeater控件的分页效果

<webdiyer:AspNetPager
ID="AspNetPager1"
runat="server"
HorizontalAlign="Center"
OnPageChanged="AspNetPager1_PageChanged"
Width="100%"
FirstPageText="首页"
NextPageText="下一页"
PrevPageText="上一页"
LastPageText="尾页"
AlwaysShow="True"
></webdiyer:AspNetPager>

后台绑定代码：

void Bind()
{
            int pageSize =  ;
            XieKe.BLL.Content con = new XieKe.BLL.Content();
            PageBase pb = new PageBase();
            pb.OrderType = ;//0 升序;1 降序
            pb.PageIndex = this.AspNetPager1.CurrentPageIndex;
            pb.PageSize = pageSize;
            pb.ProcedureName = "pagination";
            pb.StrWhere = " ";
            pb.StrGetFields = "*";
            pb.FldName = "id";
            pb.TblName = "tb_ReceiveRecord";

            int count = ;//总条数
            pb.DoCount = ; //表示只获取总数
            con.GetList(pb, ref count);
            pb.DoCount = ; //表示获取数据
            DataTable dt = con.GetList(pb, ref count).Tables[];
            this.Repeater1.DataSource = dt;
            this.Repeater1.DataBind();
            //数据分页
            AspNetPager1.PageSize = pageSize;
            AspNetPager1.RecordCount = count;
            if (count <= pb.PageSize)
                AspNetPager1.Visible = false;
            else
                AspNetPager1.Visible = true;
