I have been looking for several hours now trying to figure out how to display a transparent back-color label over other controls. I have a user-control with tons of controls in it such as text-boxes, combo-boxes, etc. I want to display a BIG RED LABEL titled "VOID" over this user-control sometimes when the control is displayed. But I want the user to still be able to read the data in the controls behind the label.
When I set the back-color property to transparent, it doesn't seem to work. I have also tried creating a custom label and over-riding the CreateParams property. Nothing seems to work.
