Can't see results in ListBox

I have thise segment of C# code:

private void btn_getPixels_Click_Click(object sender, EventArgs e)
{
    listBox1.Items.Clear();
    listBox1.Items.Add("Pixel             Color");
    try
    {
        Bitmap img = new Bitmap(pictureBox1.Image);
        Color c;

        for (int i = 0; i < img.Width; i++)
        {
            for (int j = 0; j < img.Height; j++)
            {
                c = img.GetPixel(i, j);
                listBox1.Items.Add(i + "," + j + "   " + c.Name);
            }
        }

        MessageBox.Show("SUCESSFULLY DONE");
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

The problem is that after external loop is done,I dont see any result in listBox1.

Any idea how to fix this problema?

I dont have any problems with your code: enter image description here

Of course, mb you have to change width and height for testing.

You code works successfully (I checked). It seems because of img.Width or img.Height are large values and your program are still working (so that you can not see an result). try this loop and see result:

    for (int i = 0; i < 50; i++)
    {
        for (int j = 0; j < 50; j++)
        {
            ...
