I wanted to put a large toggle button on my custom ribbon similar to the Print Layout button that appears in the Document Views group of the Word View tab.

When I added a ToggleButton to my custom tab in the VSTO ribbon designer, I get something like the following:

In the picture above, the two buttons surrounded by the dotted line are two ToggleButton controls side-by-side with an image set.

Looking at the ToggleButton properties, there is no ControlSize property which is the property I believe would style the button like the Print Layout button.

I’ve also tried setting via code to no affect.

I’m researching the issue and will hopefully post a solution soon.

SOLVED: If you put the ToggleButton controls in a ButtonGroup, the ControlSize property doesn’t apply.
