Repeater、GirdView、DataList通用的分页代码

前台代码：

<div class="tggl_2">
        每页显示&nbsp;
        <asp:DropDownList ID="ddlPageSize" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ddlPageSize_SelectedIndexChanged">
              <asp:ListItem Value="10">10</asp:ListItem>
              <asp:ListItem Value="20">20</asp:ListItem>
              <asp:ListItem Value="30">30</asp:ListItem>
              <asp:ListItem Value="40">40</asp:ListItem>
              <asp:ListItem Value="50">50</asp:ListItem>
       </asp:DropDownList>
         &nbsp;条&nbsp;&nbsp; 共&nbsp;<asp:Label ID="lblRecordCount" runat="server" Text=""></asp:Label>&nbsp;条信息&nbsp;&nbsp;
         第&nbsp;<asp:Label ID="lblPageIndex" runat="server" Text=""></asp:Label>&nbsp;页 /
         共&nbsp;<asp:Label ID="lblPageCount" runat="server" Text=""></asp:Label>&nbsp;页&nbsp;&nbsp;
          <asp:Button ID="btnFirst" runat="server" Text="首 页" OnClick="btnFirst_Click" />&nbsp;&nbsp;
          <asp:Button ID="btnPrev" runat="server" Text="上一页" OnClick="btnPrev_Click" />&nbsp;&nbsp;
          <asp:Button ID="btnNext" runat="server" Text="下一页" OnClick="btnNext_Click" />&nbsp;&nbsp;
          <asp:Button ID="btnLast" runat="server" Text="尾 页" OnClick="btnLast_Click" />&nbsp;&nbsp;
           转到第<input type="text" id="textfield" size="3" onkeyup="javascript:checkIsInt();"
            runat="server" />
            页
            <asp:Button ID="btnGoPageIndex" class="smallbutton" runat="server" Text="GO" Style="border: 0;
             20px; height: 15px;" OnClick="btnGoPageIndex_Click" />&nbsp;&nbsp;
            <input name="chkall" type="checkbox" id="chkall" value="select" onclick="CheckAll(this.form)" /><label
            for="chkAll">全选</label>&nbsp;&nbsp;
            <asp:Button ID="btnDel" runat="server" OnClick="btnDel_Click" Text="批量删除" OnClientClick="return delIt()" />
 </div>
