Create a new JScsrip.js file
The code is as follows :

Copy code The code is as follows:

 
function setPgb(pgbID, pgbValue,pvalues) 
{ 
if ( pgbValue <= pvalues ​​) 
{ 
if (lblObj = document.getElementById(pgbID '_label')) 
{ 
lblObj.innerHTML =Math.ceil(( pgbValue/pvalues)*100) '%'; // change the label value 
} 
if ( pgbObj = document.getElementById(pgbID) ) 
{ 
var divChild = pgbObj.children[0 ]; 
pgbObj.children[0].style.width = Math.ceil((pgbValue/pvalues)*240);//pgbValue; 
} 
window.status = "Data reading number" pgbValue "Bar, please wait"; 
} 
if ( pgbValue == pvalues ​​) 
{ 
window.status = "Data reading has been completed"; 
proBar.style.display ="none"; 
Table1.style.display="none"; 
} 
} 

Create a common.css
The code is as follows:

Copy code The code is as follows:

 
.bi-loading-status 
{ 
/** //*position: absolute;*/

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); 
} 

Create a progressbar.htm
The code is as follows:

Copy code The code is as follows:

< /table>

Create a Default.aspx file
The frontend code is as follows:

Copy code The code is as follows:

< ;asp:GridView ID="GridView1" runat="server">

The background code is as follows:

Copy code The code is as follows:

public partial class _Default : System.Web.UI.Page 
{ 
DataSet ds; 
text ts = new text(); 
int count = 0; 
#region Page_Load 
private void Page_Load(object sender, System.EventArgs e) 
{ 
if (!Page.IsPostBack) 
{ 
ds = Getgridview(); 
count = ds.Tables[0].Rows.Count; 
Response.Write("count="   count); 
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(ds); 
// Getgridview(); 
//load数据 
thread.Join(); 
} 
} 
#endregion fixedHeader 
#region Getgridview 
protected DataSet Getgridview() 
{ 
ds = ts.QueryProcS("2009/07", "XXXX");//这个是逻辑层中的一个方法 
return ds; 
} 
#endregion 
#region ThreadProc 
private void ThreadProc() 
{ 
string strScript = "<script>setPgb('pgbMain','{0}','"   count   "');</script>"; 
for (int i = 0; i <= count; i  ) 
{ 
System.Threading.Thread.Sleep(80); 
Response.Write(string.Format(strScript, i)); 
Response.Flush(); 
} 
} 
#endregion LoadData 
#region LoadData 
private void LoadData(DataSet dds) 
{ 
for (int m = 0; m < count; m  ) 
{ 
for (int i = 0; i < dds.Tables[0].Columns.Count; i  ) 
{ 
} 
} 
this.GridView1.DataSource = dds.Tables[0].DefaultView; 
this.GridView1.DataBind(); 
} 
#endregion Web Form Designer generated code 
#region Web Form Designer generated code 
override protected void OnInit(EventArgs e) 
{ 
// 
// CODEGEN: This call is required by the ASP.NET Web Form Designer. 
// 
InitializeComponent(); 
base.OnInit(e); 
} 
/**/ 
///  
/// Required method for Designer support - do not modify 
/// the contents of this method with the code editor. 
/// 
private void InitializeComponent() 
{ 
//this.Load  = new System.EventHandler(this.Page_Load); 
} 
#endregion 
}
