Transparent control over PictureBox

Question

In my C# Form I have a Label that displays a download percentage in the download event:

  this.lblprg.Text = overallpercent.ToString(\"#0\") + \"%\";
         


        

Answer 1

You can draw text using TextRenderer which will draw it without background:

private void pictureBox1_Paint(object sender, PaintEventArgs e)
{
    TextRenderer.DrawText(e.Graphics, 
                          overallpercent.ToString("#0") + "%", 
                          this.Font, 
                          new Point(10, 10), 
                          Color.Red);
}

When overallpercent value changes, refresh pictureBox:

pictureBox1.Refresh();

You can also use Graphics.DrawString but TextRenderer.DrawText (using GDI) is faster than DrawString (GDI+)
