Hi John, If memory serves me well, you cannot set background colors to buttons (= list box headers).
Lately I had to do a date picker with colored "special" dates (e.g. suggested dates) and after some tries with a form with buttons (a button for each date) I switched to a list box (where you can set a background color for each cell, but not for the header) because of that "missing feature".

I have tried… OBJECT SET RGB COLORS(*;"Day"+String($k)+”Header”;Foreground color;$weekEndColor) OBJECT SET COLOR OBJECT SET COLOR(*;"Day"+String($k)+"Header";-(Foreground color +(256* weekEndColor))) I can get the foreground color to work, but not the background. Or is it just not possible to set header background colors programmatically? Can’t find anything in the Docs.
