This time I would like to indicate some columns are inactive in the stack of usercontrols. My thought was to simply use DrawLine to draw an X over the column. However, everything I have tried draws the X under the usercontrols instead of on top.
The only way I got it to draw on top was to use ControlPaint.DrawReversibleLine, but I need thicker lines and that is not changable.
I also tried adding pictureboxes and locating them over the columns, but they also appear under the usercontrols.
How can I place an indicator on top of the usercontrols?
