<asp:Panel + PagedDataSource 实现 分页 （小数据量）

<asp:Panel runat="server" ID="pagepanel" Width="501px">
<asp:Label runat="server" ID="countlabel"></asp:Label>
<asp:Label runat="server" ID="currentlabel"></asp:Label>
<asp:HyperLink runat="server" ID="firstlinkbutton" Text="首页"></asp:HyperLink>
<asp:HyperLink runat="server" ID="prevlinkbutton" Text="上一页"></asp:HyperLink>
<asp:HyperLink runat="server" ID="newlinkbutton" Text="下一页"></asp:HyperLink>
<asp:HyperLink runat="server" ID="lastlinkbutton" Text="尾页"></asp:HyperLink>
转到<asp:TextBox ID="TextBox1" runat="server" Width="19px"></asp:TextBox>页
<asp:Button ID="Button1" runat="server" Text="Go" OnClick="Button1_Click" />
</asp:Panel>
<asp:HiddenField ID="HiddenField1" runat="server" />
