I've heard you can set parts of your UserControl to transparent. All you have to do is to draw a "bitmap" (or JPG) This BMP should be in Black&White. The background of your BMP (what will be the transparent areas) should be white, and the portions of your UserControl that you want to be visible, should be painted in black. Then, you have to load this image in your UserControl.MaskPicture, set the UserControl.MaskColor to White and set the UserControl.BackStyle to Transparent.
