styling toolbar Customize Thumb

Dec 23, 2008 at 11:40 AM
I am trying to style the toolbar control. I can easily set the background property as I wish. however at the end of the toolbar there is a so small thumb which is used to show "Add Or Remove Buttons" which appears to be a standard feature of toolbar controls.

I am unable to style this. The background style doesn't take effect on this portion of the toolbar.

Does anyone how to style this?

Or as an alternative disable this so it doesnt show up.

Thank you
