最近在討論區看到這個問題,小弟利用asp.net ajax的timer來實作這個功能

利用timer每隔一段時間,讓gridview自動跳頁並且更新gridview的內容

asp.net(c#)

GridviewAutoPage.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="GridviewAutoPage.aspx.cs"
    Inherits="GridviewAutoPage" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>GridviewAutoPage</title>
    <meta http-equiv="Page-Enter" content="blendTrans(duration=1)" />
    <meta http-equiv="Page-Exit" content="blendTrans(duration=1)" />
</head>
<body>
    <form id="form1" runat="server">
        <div>
            <asp:ScriptManager ID="ScriptManager1" runat="server">
            </asp:ScriptManager>
            <asp:UpdatePanel ID="UpdatePanel1" runat="server">
                <ContentTemplate>
                    <asp:GridView ID="GridView1" runat="server" AllowPaging="True" PageSize="1">
                    </asp:GridView>
                </ContentTemplate>
                <Triggers>
                    <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
                </Triggers>
            </asp:UpdatePanel>
        </div>
        <asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="Timer1_Tick">
        </asp:Timer>
    </form>
</body>
</html>

GridviewAutoPage.aspx.cs

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;


public partial class GridviewAutoPage : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            LoadData();
        }

    }


    protected void LoadData()
    {
        this.GridView1.DataSource = new string[] { "Dotblogs", "F6 Team", "puma" };
        this.GridView1.DataBind();
    }


    protected void Timer1_Tick(object sender, EventArgs e)
    {
        if (this.GridView1.PageCount > 1)
        {
            if (this.GridView1.PageIndex == this.GridView1.PageCount - 1)
            {
                this.GridView1.PageIndex = 0;
                LoadData();
            }

            else
            {
                this.GridView1.PageIndex = this.GridView1.PageIndex + 1;
                LoadData();
            }

        }

    }

}

執行結果:
