Supply the ColorDialog Property with a fake one?

Unfortunately that gives an "Invalid property value" error

Ok, this do this instead.

in the OnClick Event use "Abort", that will skip it.

What are you trying to achieve? Without the ColorDialog you cannot change the color - the TColorButton is useless then. Or do you just want to display a color? Use a TShape or a TPanel instead.

In certain situations I don't want the color dialog displayed, disabling the button would probably be the user friendly route but I have a lot of TColorbuttons, over 50 of of them !! so I'm just working on the best way to 'disable' the TColorButton.

That control has animated button action and if you still want to use the OnClick for some processing, you can. Simply use "Abort" before it exits and the internal Dialog wont popup.

 I find a few controls in the system that are like that via the OnClick where you can have the default action get ignored. I am not an advocate of using try ... Except/Finally all over the place but it works out there.
