Reasons for why a WinForms label does not want to be transparent?

Question

Why can't I set the BackColor of a Label to Transparent? I have done it before, but now it just don't want to...

I created a new UserControl, added a progressbar and a label to it. When I set the BackColor of the label to transparent it is still gray =/ Why is this?

What I wanted was to have the label on top of the progressbar so that its text was "in" the progressbar...

Add a new class to your project and post the code shown below. Build. Drop the new control from the top of the toolbox onto your form.

using System; using System.Windows.Forms;  public class TransparentLabel : Label {   public TransparentLabel() {     this.SetStyle(ControlStyles.Opaque, true);     this.SetStyle(ControlStyles.OptimizedDoubleBuffer, false);   }   protected override CreateParams CreateParams {     get {       CreateParams parms = base.CreateParams;       parms.ExStyle |= 0x20;  // Turn on WS_EX_TRANSPARENT       return parms;     }   } }
