ASP.NET中GridView分页

方法一:
新建一个页面然后在页面拖一个GridView控件在属性框中设置GridView控件的AllowPaing属性为True 然后再设置GridView的PageSize属性,源文件如下:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames ="classId" CellPadding="5" OnRowDeleting="GridView1_RowDeleting" AllowPaging="True" OnPageIndexChanging="GridView1_PageIndexChanging" PageSize ="15">
            <Columns>
                <asp:BoundField DataField ="className" HeaderText ="名称" />
                <asp:BoundField DataField="classDes" HeaderText="描述" SortExpression="classDes" />
         </Columns>
          <PagerTemplate>
               <table style="font-size :12px;">
               <tr>
           
                 <td> 总共<asp:Label ID="Label1" runat="server" Text="<%#((GridView)Container.NamingContainer).PageCount %>"></asp:Label>页 &nbsp; </td>
               
                    <td> 第<asp:Label ID="Label2" runat="server" Text="<%#((GridView)Container.NamingContainer).PageIndex+1 %>"></asp:Label>页 &nbsp;</td>
