Override OnPaint and draw the text at the label position manually.

-Chris

You could draw the text yourself instead of using labels.  I'm not sure
how to do this in mobile but on the desktop I have set the color to a
unused color (like purple) and then filter out that color to make it
transparent.

you can create your custom control that will draw its parent background color
onto itself and then draw the text over.  If the parent happens to have an
image background, get that image and draw the portion of the image that the
custom label control is on.

Here is the sample code:

public class CustomLabel : Control {
 protected override void OnPaint(PaintEventArgs e)
 {       
       e.Graphics.DrawImage(parentBackgroundImage, new Rectangle(0, 0,
this.Width, this.Height), new Rectangle(this.Left, this.Top, this.Width,
this.Height), GraphicsUnit.Pixel);
       e.Graphics.DrawString(text, font, brush, new RectangleF(0, 0,
this.Width, this.Height)
 }
}
