I have a PictureBox Control on user control. The image the picturebox
contains is transparent. At design time I can set the BackColor property to
anything I want and it behaves exactly as expected and looks great . When I
try to change the backColor property at runtime it does not change it
remains at whatever I set it to at design time.

Assistance appreciated.

TIA

It works just fine for me.

Bitmap
img=(Bitmap)Image.FromStream(this.GetType().Assemb ly.GetManifestResourceStream("pbbackcolor.Bitmap1. bmp"));

this.pictureBox1.Image = img;
