Code For Progress Bar In Windows Application Using C#.NET

This article will teach you how you can show the progress bar in Windows applications, using C#.NET. So, for this application, first we will create a new Windows application and add a progress bar control.

 

 

 

Now, we will assign the maximum value to the progress bar control. This will help to show the progress.

 

 

 

After this control setting, we will add a backgroundWorker control.

 

 

 

Now, generate the  DoWork and ProgressChanged event for the control backgroundWorker.

 

 

After this, we will add the code on DoWork event.

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
    {
        for (int i = 1; i <= 100; i++)
        {
        // Wait 50 milliseconds.
        Thread.Sleep(50);
        // Report progress.
        backgroundWorker1.ReportProgress(i);
        }
    }

 Now, we will add the code for ProgressChanged.

private void backgroundWorker1_ProgressChanged(object sender,
        ProgressChangedEventArgs e)
    {
        // Change the value of the ProgressBar
        progressBar1.Value = e.ProgressPercentage;
        // Set the text.
        this.Text = e.ProgressPercentage.ToString();
    }

Now, we will add the code to invoke the backgroundWorker.

private void Form2_Load(object sender, System.EventArgs e)
{
        backgroundWorker1.WorkerReportsProgress = true;
        backgroundWorker1.RunWorkerAsync();
}

So, here is the complete code of what we have done. 

using System.ComponentModel;
using System.Threading;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form2 : Form
    {
    public Form2()
    {
        InitializeComponent();
    }

    private void Form2_Load(object sender, System.EventArgs e)
    {
            backgroundWorker1.WorkerReportsProgress = true;
            backgroundWorker1.RunWorkerAsync();
    }

    private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
    {
        for (int i = 1; i <= 100; i++)
        {
        // Wait 50 milliseconds.
        Thread.Sleep(50);
        // Report progress.
        backgroundWorker1.ReportProgress(i);
        }
    }

    private void backgroundWorker1_ProgressChanged(object sender,
        ProgressChangedEventArgs e)
    {
        // Change the value of the ProgressBar
        progressBar1.Value = e.ProgressPercentage;
        // Set the text.
        this.Text =  "Progress: " + e.ProgressPercentage.ToString() + "%";
    }
    }
}

 Now, we are done. Run the application to check the output.
