我们先看下效果
我点击了按钮后他会显示进度页面，进度完成后，进度条消失，其实也是比较简单的了。
我们需要一个进度条代码文件ProgressBar.htm（注意：是没有head这些标签的）
<script language="javascript">
function SetPorgressBar(pos)
//设置进度条居中
var screenWidth = document.body.offsetWidth;
ProgressBarSide.style.width = Math.round(screenWidth / 2) + "px";
ProgressBarSide.style.left = Math.round(screenWidth / 4) + "px";
ProgressBarSide.style.top = "50px";
ProgressBarSide.style.height = "21px";
ProgressBarSide.style.display = "block";
//设置进度条百分比
ProgressBar.style.width = pos + "%";
ProgressText.innerHTML = pos + "%";
function SetMaxValue(maxValue)
ProgressBarSide.style.width = maxValue + "px";
//完成后隐藏进度条
function SetCompleted()
ProgressBarSide.style.display = "none";
function SetTitle(title)
ProgressTitle.innerHTML = title;
</script>
<div id="ProgressBarSide" style="position: absolute; height: 21px; width: 100px;
color: Silver; border-width: 1px; border-style: Solid; display: block">
<div id="ProgressBar" style="position: absolute; height: 21px; width: 0%; padding: 0px; color: rgb(0, 0, 255); line-height: 1.5 !important;">>
</div>
<div id="ProgressText" style="position: absolute; height: 21px; width: 100%; text-align: center">
</div>
<div id="ProgressTitle" style="position: absolute; height: 21px; top: 21px; width: 100%;
text-align: center">
</div>
</div>
然后需要一个进度条类ProgressBar.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;
namespace ZhuoYueE.Dop.Web.UI
/// <summary>
///显示进度条
/// </summary>
public class ProgressBar : System.Web.UI.Page
/// <summary>
/// 最大值
/// </summary>
private int MaxValue
get
if (ViewState["MaxValue"] == null)
return 0;
else
return Convert.ToInt32(ViewState["MaxValue"]);
set
ViewState["MaxValue"] = value;
/// <summary>
/// 当前值
/// </summary>
private int ThisValue
get
if (ViewState["ThisValue"] == null)
return 0;
else
return Convert.ToInt32(ViewState["ThisValue"]);
set
ViewState["ThisValue"] = value;
/// <summary>
/// 当前页面
/// </summary>
System.Web.UI.Page m_page;
/// <summary>
/// 功能描述:构造函数
/// 作 者:huangzh
/// 创建日期:2016-05-06 11:54:34
/// 任务编号:
/// </summary>
/// <param name="page">当前页面</param>
public ProgressBar(System.Web.UI.Page page)
m_page = page;
public void SetMaxValue(int intMaxValue)
MaxValue = intMaxValue;
/// <summary>
/// 功能描述:初始化进度条
/// 作 者:huangzh
/// 创建日期:2016-05-06 11:55:26
/// 任务编号:
/// </summary>
public void InitProgress()
//根据ProgressBar.htm显示进度条界面
string templateFileName = AppDomain.CurrentDomain.BaseDirectory + "ProgressBar.htm";
StreamReader reader = new StreamReader(@templateFileName, System.Text.Encoding.GetEncoding("GB2312"));
string strhtml = reader.ReadToEnd();
reader.Close();
m_page.Response.Write(strhtml);
m_page.Response.Flush();
/// <summary>
/// 功能描述:设置标题
/// 作 者:huangzh
/// 创建日期:2016-05-06 11:55:36
/// 任务编号:
/// </summary>
/// <param name="strTitle">strTitle</param>
public void SetTitle(string strTitle)
string strjsBlock = "<script>SetTitle(\'" + strTitle + "\'); </script>";
m_page.Response.Write(strjsBlock);
m_page.Response.Flush();
/// <summary>
/// 功能描述:设置进度
/// 作 者:huangzh
/// 创建日期:2016-05-06 11:55:45
/// 任务编号:
/// </summary>
/// <param name="percent">percent</param>
public void AddProgress(int intpercent)
ThisValue = ThisValue + intpercent;
double dblstep = ((double)ThisValue / (double)MaxValue) * 100;
string strjsBlock = "<script>SetPorgressBar(\'" + dblstep.ToString("0.00") + "\'); </script>";
m_page.Response.Write(strjsBlock);
m_page.Response.Flush();
public void DisponseProgress()
string strjsBlock = "<script>SetCompleted();</script>";
m_page.Response.Write(strjsBlock);
m_page.Response.Flush();
然后就是调用方法了，调用很简单，在页面的按钮事件或者其他什么地方加入代码，如在按钮事件里这么用
protected void btnImport_Click(object sender, EventArgs e)
ProgressBar pb = new ProgressBar(this);
pb.SetMaxValue(110);
pb.InitProgress();
pb.SetTitle("这是一个测试数据");
for (int i = 1; i <= 110; i++)
pb.AddProgress(1);
//此处用线程休眠代替实际的操作，如加载数据等
System.Threading.Thread.Sleep(50);
pb.DisponseProgress();
怎么样，是不是很简单呢。
