Repeater、GirdView、DataList通用的分页代码_.NET_编程开发_程序员俱乐部

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>

         &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="btnLast" runat="server" Text="尾 页" OnClick="btnLast_Click" />&nbsp;&nbsp;
           转到第<input type="text" id="textfield" size="3" onkeyup="javascript:checkIsInt();"

            页
