Question

iam尝试使用以下代码为我的datalist使用分页...我能够做到服务器端但我怎么能做到客户端...我的意思是我已经在页面加载时绑定了我的datalist ..alli需要是允许在客户端进行分页

ASPX

<asp:LinkButton ID="LinkButton3" runat="server" CommandName="Previous" Text="<< Previous"
                            OnClick="Pager_Click"></asp:LinkButton>
                        &nbsp;&nbsp;&nbsp;&nbsp;
                        <input id="Button6" type="button" value="close" onclick="Hidee2()" />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
                        <asp:LinkButton ID="LinkButton4" runat="server" CommandName="Next" Text="Next >>"
                            OnClick="Pager_Click"></asp:LinkButton>

您可以使用.netslackers DataControls（http://dotnetslackers.com/projects/AjaxDataControls/）

这些是纯客户端控件

使用javascript在datalist中进行分页
