Button Cell type

Hello,

I am using spread version 8.0.20. I am using button cell type to set image and text in same cell.
I am not able to set the button color. I tried sample example which used functions like "SetTypeButtonColor", "SetTypeButtonDarkColor", "SetTypeButtonLightColor" and "SetTypeButtonBorderColor" but nothing happens.

See attached image(CellImage.bmp) of what i want to do.

Programming language used is VC++.

Can anybody provide code snippet?

Thank you
