Answer 1

It's BackColor property did not work by default: Accorthing this (ToolStripSplitButton BackColor does not work), follow these two steps:

1) Set BackgroundImage to a valid image. It does not matter what. I use a 1 pixel x 1 pixel BMP as local resource.

2) Set BackgroundImageLayout to None. This is why it does not matter what image you use above.
