利用ASP.NET AJAX的Timer讓GridView每隔一段時間做到自動換頁的功能

 

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:
