建立Htm文件(文件名:progressbar.htm)

function setPgb(pgbID, pgbValue)

{

if ( pgbValue <= 100 )

{

//debugger;

if (lblObj = document.getElementById(pgbID+'_label'))

{

lblObj.innerHTML = pgbValue + '%'; // change the label value

}

if ( pgbObj = document.getElementById(pgbID) )

var divChild = pgbObj.children[0];

pgbObj.children[0].style.width = pgbValue + "%";

}

window.status = "数据读取" + pgbValue + "%，请稍候

}

if ( pgbValue == 100 )

window.status = "数据读取已经完成";

proBar.style.display="none";

Table1.style.display="none";

}

</script>

<html>

<head>

</head>

<tr>

</DIV>

</td>

</tr>

</table>

</body>

</html>

用到的Css文件如下(common.css)：

.bi-loading-status {

}{

/**//*position: absolute;*/

width: 150px;

padding: 1px;

overflow: hidden;

}

.bi-loading-status .text {

}{

white-space: nowrap;

overflow: hidden;

width: 100%;

text-overflow: ellipsis;

padding: 1px;

}

.bi-loading-status .progress-bar {

}{

border: 1px solid ThreeDShadow;

background: window;

height: 10px;

width: 100%;

padding: 1px;

overflow: hidden;

}

.bi-loading-status .progress-bar div {

}{

background: Highlight;

overflow: hidden;

height: 100%;

filter: Alpha(Opacity=0, FinishOpacity=100, Style=1, StartX=0, StartY=0, FinishX=100, FinishY=0);

}

HTML (WebForm1.aspx)代码：

@ Page language="c#" Codebehind="WebForm1.aspx.cs" AutoEventWireup="false" Inherits="WebApplication3.WebForm1" %>

<HTML>

<HEAD>

<title>progressbar</title>

</HEAD>

<%=fixedHeader()%>

</form>

</body>

</HTML>

.Net 代码(WebForm1.aspx.cs)：
引用如下：

using System;

using System.Collections;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Web;

using System.Web.SessionState;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.HtmlControls;

using System.Threading;

using System.IO;

using System.Text;
Page_Load事件里面代码：

Page_Load#region Page_Load

private void Page_Load(object sender, System.EventArgs e)

{

if(!Page.IsPostBack)

{

string strFileName =Server.MapPath("progressbar.htm" );

StreamReader sr = new StreamReader( strFileName, System.Text.Encoding.Default );

string strHtml = sr.ReadToEnd();

Response.Write( strHtml );

sr.Close();

Response.Flush();

Thread thread = new Thread(new ThreadStart(ThreadProc));

thread.Start();

LoadData();//load数据

thread.Join();

}

#endregion
其中

Thread thread = new Thread(new ThreadStart(ThreadProc));

thread.Start();
是开始线裎
调用以下方法fixedProc()：

ThreadProc#region ThreadProc

private void ThreadProc()

{

string strScript = "<script>setPgb('pgbMain','{0}');</script>";

for ( int i = 0; i <= 100; i++ )

{

System.Threading.Thread.Sleep(10);

Response.Write( string.Format( strScript, i));

Response.Flush();

}

#endregion

WebForm1.aspx里面调用的HTML代码：

fixedHeader#region fixedHeader

protected string fixedHeader()

{

StringBuilder s=new StringBuilder();

s.Append(@"<table width='100%' border='1' cellspacing='0' style='MARGIN-TOP:-2px'>");

s.Append(@"<TR class='fixedHeaderTr' style='BACKGROUND:navy;COLOR:white'>");

s.Append(@"<TD nowrap>Header A</TD>");

s.Append(@"<TD nowrap>Header B</TD>");

s.Append(@"<TD nowrap>Header C</TD>");

s.Append(@"</TR>");

for(int m=0;m<100;m++)

{

s.Append(@"<TR>");

s.Append(@"<TD>A").Append(m).Append("</TD>");

s.Append(@"<TD>B").Append(m).Append("</TD>");

s.Append(@"<TD>C").Append(m).Append("</TD>");

s.Append(@"</TR>");

}

s.Append(@"</table>");

return s.ToString();

}

#endregion

方法LoadData()：

LoadData#region LoadData

private void LoadData()

{

for(int m=0;m<90000;m++)

{

for(int i=0;i<90000;i++)

{

}

#endregion
