Can you please use Syntax highlighter code? Its a foramt to display code. I cannot read the code you have put in such format.

My progress bar doesn't update until the loop has finished.

Raghav Jhavar · Answer

Please tell us what you are looping through? I will assume its a list in this example: List ToLoop = new List (); //Lets say it has 50 elements int Looped = 0; foreach ( string SingleString in ToLoop) { //Do some work here with SingleString Looped++; //Assume the progressBar is from 0-100 progressBar.Value = (Looped / ToLoop.Count) * 100; }

Hii Raghav Thanks For Your Reply. I will share complete code aspx code:- --%> var y = new Array(); debugger; function getImage(path, length) { debugger; var bar; bar.wait({ interval: length, duration: 1000, text: path, scope: bar, //fn: function () { // this.updateText('Done!'); //} }); } [Code Behind] using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Data.OleDb; using System.Linq; using System.Text; using System.Threading; using System.Windows; //using System.Windows.Data; using System.Windows.Forms; using System.Windows.Input; //using System.Windows.Media; using Ext.Net; public partial class BackgroundWorkerAndProgressBar : System.Web.UI.Page { private BackgroundWorker BackWorker = null; protected void Page_Load(object sender, EventArgs e) { //worker = new BackgroundWorker(); //worker.WorkerReportsProgress = true; //worker.WorkerSupportsCancellation = true; //worker.DoWork += new DoWorkEventHandler(worker_DoWork); //worker.ProgressChanged += new ProgressChangedEventHandler(worker_ProgressChanged); //worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(worker_RunWorkerCompleted); BackWorker = new BackgroundWorker(); BackWorker.DoWork += new DoWorkEventHandler(backgroundWorker1_DoWork); BackWorker.ProgressChanged += new ProgressChangedEventHandler (backgroundWorker1_ProgressChanged); BackWorker.RunWorkerCompleted += new RunWorkerCompletedEventHandler (backgroundWorker1_RunWorkerCompleted); BackWorker.WorkerReportsProgress = true; BackWorker.WorkerSupportsCancellation = true; } private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e) { //object progress = this.Session["LongActionProgress"]; //this.progressBar1.UpdateProgress(((int)e.ProgressPercentage) / 10f, string.Format("Step {0} of {1}...", e.ProgressPercentage.ToString(), 10)); // Thread.Sleep(1000); this.progressBar1.UpdateProgress(((float)e.ProgressPercentage) / 10f, string.Format("Step {0} of {1}...", e.ProgressPercentage.ToString(), 10)); //label1.Show(); label1.Text = "Processing......"+ e.ProgressPercentage.ToString() + "%"; label1.Show(); //Response.Write("pp"); // progressBar1.Text = "reading " + e.ProgressPercentage + " out of 100"; //progressBar1.UpdateProgress(e.ProgressPercentage); // X.Msg.Alert("", "Processing......" + progressBar1.Value.ToString() + "%").Show(); // progressBar1.AddScript("getImage('Processing......','" + (int)e.ProgressPercentage + "');"); //'" + imgName + "', } private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { if (e.Cancelled) { label1.Text = "Task Cancelled."; } else if (e.Error != null) { label1.Text = "Error while performing background operation."; } else { label1.Text = "Task Completed..."; } button1.Enabled = true; button2.Enabled = false; } private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e) { for (int i = 0; i { //this.Session["LongActionProgress"] = i + 1; Thread.Sleep(100); BackWorker.ReportProgress(i); // progressBar1.Text = "reading " + i + " out of 100"; if (BackWorker.CancellationPending) { e.Cancel = true; BackWorker.ReportProgress(0); return; } else { Thread.Sleep(100); } } // this.Session.Remove("LongActionProgress"); BackWorker.ReportProgress(10); } protected void button1_Click(object sender, DirectEventArgs e) { button1.Enabled = false; button2.Enabled = true; //this.Session["LongActionProgress"] = 0; BackWorker.RunWorkerAsync(); } protected void button2_Click(object sender, DirectEventArgs e) { if (BackWorker.IsBusy) { BackWorker.CancelAsync(); } } //void worker_ProgressChanged(object sender, ProgressChangedEventArgs e) //{ // pBar.Value = e.ProgressPercentage; // lblStatus.Text = "Processing......" + pBar.Value.ToString() + "%"; //} //private void worker_DoWork(object sender, DoWorkEventArgs e) //{ // // do your task here // for (int i = 0; i // { // Thread.Sleep(500); // if (worker == null) // break; // worker.ReportProgress(i); // } //} //private void worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) //{ // lblStatus.Text = "Task finished"; //} //private void Button_Click(object sender, EventArgs e) //{ // if (worker == null) // { // worker = new BackgroundWorker(); // worker.DoWork += worker_DoWork; // worker.RunWorkerCompleted += worker_RunWorkerCompleted; // worker.ProgressChanged += worker_ProgressChanged; // worker.WorkerReportsProgress = true; // worker.WorkerSupportsCancellation = true; // } // if (worker.IsBusy != true) // { // // Start the asynchronous operation. // worker.RunWorkerAsync(); // } //} //private void Window_Loaded(object sender, EventArgs e) //{ // pBar.Maximum = 100; //} //private void btnCancel_Click(object sender, EventArgs e) //{ // worker.CancelAsync(); // worker = null; //} }
