It should not make difference in different Windows versions.

It' doesn't work. Maybe in Windows 7 but not in Windows XP

Hello Luis,

You can try the following:

Color transparentColor = Color.Transparent;

nRichTextLabel1.FillInfo.FillStyle = FillStyle.Solid;
nRichTextLabel1.FillInfo.Color = transparentColor;
nRichTextLabel1.PaletteInheritance = PaletteInheritance.None;
nRichTextLabel1.Palette.ControlBorder = transparentColor;

Is it possible to create a NRichTextLabel transparent in Windows XP ?
